ThursdAI - Apr 3rd - OpenAI Goes Open?! Gemini Crushes Math, AI Actors Go Hollywood & MCP, Now with Observability?

Woo! Welcome back to ThursdAI, show number 99! Can you believe it? We are one show away from hitting the big 100, which is just wild to me. And speaking of milestones, we just crossed 100,000 downloads on Substack alone! [Insert celebratory sound effect here 🎉]. Honestly, knowing so many of you tune in every week genuinely fills me with joy, but also a real commitment to keep bringing you the the high-signal, zero-fluff AI news you count on. Thank you for being part of this amazing community! 🙏And what a week it's been! I started out busy at work, playing with the native image generation in ChatGPT like everyone else (all 130 million of us!), and then I looked at my notes for today… an absolute mountain of updates. Seriously, one of those weeks where open source just exploded, big companies dropped major news, and the vision/video space is producing stuff that's crossing the uncanny valley.We’ve got OpenAI teasing a big open source release (yes, OpenAI might actually be open again!), Gemini 2.5 showing superhuman math skills, Amazon stepping into the agent ring, truly mind-blowing AI character generation from Meta, and a personal update on making the Model Context Protocol (MCP) observable. Plus, we had some fantastic guests join us live!So buckle up, grab your coffee (or whatever gets you through the AI whirlwind), because we have a lot to cover. Let's dive in! (as always, show notes and links in the end)OpenAI Makes Waves: Open Source Tease, Tough Evals & Billions RaisedIt feels like OpenAI was determined to dominate the headlines this week, hitting us from multiple angles.First, the potentially massive news: OpenAI is planning to release a new open source model in the "coming months"! Kevin Weil tweeted that they're working on a "highly capable open language model" and are actively seeking developer feedback through dedicated sessions (sign up here if interested) to "get this right." Word on the street is that this could be a powerful reasoning model. Sam Altman also cheekily added they won't slap on a Llama-style Second, they dropped PaperBench, a brutal new benchmark evaluating an AI's ability to replicate ICML 2024 research papers from scratch (read paper, write code, run experiments, match results - no peeking at original code!). It's incredibly detailed (>8,300 tasks) and even includes meta-evaluation for the LLM judge they built (Nano-Eval framework also open sourced). The kicker? Claude 3.5 Sonnet (New) came out on top with just 21.0% replication score (human PhDs got 41.4%). Props to OpenAI for releasing an eval where they don’t even win. That’s what real benchmarking integrity looks like. You can find the code on GitHub and read the full paper here.Third, the casual 40 Billion Dollars funding round led by SoftBank. Valuing the company at 300 Billion. Yes, Billion with a B. More than Coke, more than Disney. The blog post was hilariously short for such a massive number. They also mentioned500 million weekly ChatGPT usersand the insane onboarding rate (1M users/hr!) thanks to native image generation, especially seeing huge growth in India. The scale is just mind-boggling.Oh, and for fun, try the new grumpy, EMO "Monday" voice in advanced voice mode. It's surprisingly entertaining.Open Source Powerhouses: Nomic & OpenHands Deliver SOTABeyond the OpenAI buzz, the open source community delivered some absolute gems, and we had guests from two key projects join us!Nomic Embed Multimodal: SOTA Embeddings for Visual DocsOur friends at Nomic AI are back with a killer release! We had Zach Nussbaum on the show discussing Nomic Embed Multimodal. These are new 3B & 7B parameter embedding models (available on Hugging Face) built on Alibaba's excellent Qwen2.5-VL. They achieved SOTA on visual document retrieval by cleverly embedding interleaved text-image sequences – perfect for PDFs and complex webpages.Zach highlighted that they chose the Qwen base because high-performing open VLMs under 3B params are still scarce, making it a solid foundation. Importantly, the 7B model comes with an Apache 2.0 license, and they've open sourced weights, code, and data. They offer both a powerful multi-vector version (ColNomic) and a faster single-vector one. Huge congrats to Nomic!OpenHands LM 32B & Agent: Accessible SOTA CodingRemember OpenDevin? It evolved into OpenHands, and the team just dropped their own OpenHands LM 32B! We chatted with co-founder Xingyao "Elle" Wang about this impressive Qwen 2.5 finetune (MIT licensed, on Hugging Face).It hits a remarkable 37.2% on SWE-Bench Verified (a coding benchmark measuring real-world repo tasks), competing with much larger models. Elle stressed they didn't just chase code completion scores; they focused on tuning for agentic capabilities – tool use, planning, self-correction – using trajectories from their contamination-free Switch Execution dataset. This focus seems to be paying off, as the OpenHands agent also snagged the #2 spot on the brand new Live SWE-Bench leaderboard! Plus, the 32B model runs locally on a single 3090, making this power accessible. You can also try their managed OpenHands Cloud ($50 free credit). Amazing progress from this team!Frontiers: Diffusion LMs & Superhuman MathTwo other developments pushed the boundaries this week:Dream 7B: A Diffusion Language Model Challenger?This one's fascinating conceptually. Researchers unveiled Dream 7B, a language model based on diffusion, not auto-regression. The benchmarks they shared show it competing strongly with top 7-8B models, and absolutely crushing tasks like Sudoku (81% vs model weights aren't out yet, so we can't verify or play with it. Still, one to watch!Gemini 2.5 Obliterates Olympiad Math (24.4% on USAMO!)We already knew Gemini 2.5 was good, but wow. New results dropped showing its performance on the USA Math Olympiad (USAMO) – problems so hard most top models score under 5%. Gemini 2.5 Pro scored an incredible 24.4%!The gap between it and everything else is massive, highlighting the power of its reasoning and thinking capabilities (which you can inspect via its traces!). Having used it for complex tasks myself (like wrestling with tax forms!), I can attest to its depth. It's free in the Gemini app – go try it!Agents, Compute & Making MCP ObservableAmazon's Nova Act Agent & The Need for AccessAmazon entered the agent chat with Nova Act, designed for web browser actions. They claim it beats Claude 3.5 and OpenAI's QA model on some benchmarks, possibly leveraging acquired Adept talent. But... it's only available via an SDK with a request form. As Yam rightly pointed out on the show, these agent claims mean little until we can actually use them in the real world!CoreWeave + NVIDIA = Insane SpeedsHardware keeps accelerating. CoreWeave announced hitting 800 Tokens/sec on Llama 3.1 405B using NVIDIA's new GB200 Blackwell chips, and 33,000 T/s on Llama 2 70B with H200s. Inference is getting fast.This Week's Buzz: Let's Make MCP Observable!Okay, my personal mission this week builds on the growing Model Context Protocol (MCP) momentum. MCP is potentially the "HTTP for agents," enabling tool interoperability. But as tool use moves external, we lose visibility, making debugging and security harder.That's why I'm launching the Observable Tools initiative. The goal: integrate observability into the MCP standard itself. Right now, that link redirects to a GitHub discussion where I've proposed using the OpenTelemetry (OTel) standard to add tracing to MCP interactions. This would give developers clear visibility into tool usage, regardless of their observability platform.I need your help! Please check out the proposal, join the discussion, and show your support with a 👍 or 🚀 on GitHub. We need the community voice to make this happen! (And yes, my viral tweet showed there's huge demand for usable MCP clients too – more on that soon!).Vision & Video: Entering the Uncanny ValleyThis space is moving at lightning speed.Runway Gen-4 was announced, pushing for better consistency in AI video. Here's a few example videos showing incredible character and world consistency:ByteDance's impressive OmniHuman (single image to talking avatar) is now publicly usable via Dreamina website. For people it's really good, but for animated style images, Hedra Labs feels actually better (and much much faster)Meta's MoCHA is mind-blowing. We had researcher Cong Wei explain how it generates movie-grade, full-body, expressive talking characters directly from speech and text (no reference image needed!). Using Diffusion Transformers and clever attention mechanisms, the realism is startling, handling lip-sync, gestures, emotions, and even multi-character dialogue. Check the project page videos – some are truly uncanny. Just look at this one!Voice Highlight: Hailuo Speech-02While Gladia launched their Solaria STT, the standout for me was Hailuo's Speech-02 TTS API. The emotional control and voice cloning quality are, in my opinion, potentially SOTA right now, offering incredibly nuanced and realistic synthetic voices.Tool Update & Breaking News!* Google's NotebookLM now discovers related sources automatically.* BREAKING NEWS (Caught end of show): Devin 2.0 is out! Cognition Labs launched their AI software engineer V2 with a new IDE experience and, crucially, a $20/month starting price. Much more accessible to try!Phew! What a week. From OpenAI's big moves to Gemini's math prowess, stunning AI actors from Meta, and the push for an observable agent ecosystem – the field is accelerating like crazy.Alright folks, that’s a wrap for show #99! Thank you again for tuning in, for being part of the community, and for keeping us on our toes with your insights and feedback.

Hey everyone, Alex here 👋 Welcome back to ThursdAI! And folks, what an absolutely insane week it's been in the world of AI. Seriously, as I mentioned on the show, we don't often get weeks this packed with game-changing releases.We saw Google emphatically reclaim the #1 LLM spot with Gemini 2.5 Pro (and OpenAI try really hard to hit back with a new ChatGPT), DeepSeek dropped a monster 685B parameter open-source model, Qwen launched a tiny but mighty 7B Omni model that handles voice and video like a champ, and OpenAI finally gave us native image generation in GPT-4o, immediately unleashing a tidal wave of Ghibli-fication across the internet. It was intense, with big players seemingly trying to one-up each other constantly – remember when Sam Altman dropped Advanced Voice Mode right when Google was about to show Astra? This weeks was this, on steroids. We had a fantastic show trying to unpack it all, joined by the brilliant Tulsee Doshi from the Google Gemini team, my Weights & Biases colleague Morgan McQuire talking MCP tools, and the MLX King himself, Prince Canuma. Plus, my awesome co-hosts Wolfram, Nisten, and Yam were there to add their insights. (watch the LIVE recap or keep reading and listen to the audio pod) So, grab your beverage of choice, buckle up, and let's try to make sense of this AI whirlwind! (TL'DR and show notes at the bottom 👇)Big CO LLMs + APIs🔥 Google Reclaims #1 with Gemini 2.5 Pro (Thinking!)Okay, let's start with the big news. Google came out swinging this week, dropping Gemini 2.5 Pro and, based on the benchmarks and our initial impressions, taking back the crown for the best all-around LLM currently available. (Check out the X announcement, the official blog post, and seriously, go try it yourself at ai.dev).We were super lucky to have Tulsee Doshi, who leads the product team for Gemini modeling efforts at Google, join us on the show to give us the inside scoop. Gemini 2.5 Pro Experimental isn't just an incremental update; it's topping benchmarks in complex reasoning, science, math, and coding. As Tulsee explained, this isn't just about tweaking one thing – it's a combination of a significantly enhanced base model and improved post-training techniques, including integrating those "thinking" capabilities (like chain-of-thought) right into the core models.That's why they dropped "thinking" from the official name – it's not a separate mode anymore, it's becoming fundamental to how Gemini operates. Tulsee mentioned their goal is for the main line models to be thinking models, leveraging inference time when needed to get the best answer. This is a huge step towards more capable and reliable AI.The performance gains are staggering across the board. We saw massive jumps on benchmarks like AIME (up nearly 20 points!) and GPQA. But it's not just about the numbers. As Tulsee highlighted, Gemini 2.5 is proving to be incredibly well-rounded, excelling not only on academic benchmarks but also on human preference evaluations like LM Arena (where style control is key). The "vibes" are great, as Wolfram put it. My own testing on reasoning tasks confirms this – the latency is surprisingly low for such a powerful model (around 13 seconds on my hard reasoning questions compared to 45+ for others), and the accuracy is the highest I've seen yet at 66% on that specific challenging set.It also inherits the strengths of previous Gemini models – native multimodality and that massive long context window (up to 1M tokens!). Tulsee emphasized how crucial long context is, allowing the model to reason over entire code repos, large sets of financial documents, or research papers. The performance on long context tasks, like the needle-in-a-haystack test shown on Live Bench, is truly impressive, maintaining high accuracy even at 120k+ tokens where other models often falter significantly.Nisten mentioned on the show that while it's better than GPT-4o, it might not completely replace Sonnet 3.5 for him yet, especially for certain coding or medical tasks under 128k context. Still, the consensus is clear: Gemini 2.5 Pro is the absolute best model right now across categories. Go play with it!ARC-AGI 2 Benchmark Revealed (X, Interactive Blog)Also on the benchmark front, the challenging ARC-AGI 2 benchmark was revealed. This is designed to test tasks that are easy for humans but hard for LLMs. The initial results are sobering: base LLMs score 0% accuracy, and even current "thinking" models only reach about 4%. It highlights just how far we still have to go in developing truly robust AI reasoning, giving us another hill to climb.GPT-4o got another update (as I'm writing these words!) tied for #1 on LMArena, beating 4.5How much does Sam want to win over Google? So much he's letting it ALL out. Just now, we saw an update from LMArena and Sam, about a NEW GPT-4o (2025-03-26) which jumps OVER GPT 4.5 (like.. what?) and lands at number 2 on the LM Arena, jumping over 3o points.Tied #1 in Coding, Hard Prompts. Top-2 across ALL categories. Besides getting very close to Gemini but not quite beating it, I gotta ask, what's the point of 4.5 then? Open Source LLMsThe open-source community wasn't sleeping this week either, with some major drops!DeepSeek V3 Update - 685B Parameter Beast!The Whale Bros at DeepSeek silently dropped an update to their V3 model (X, HF), and it's a monster. We're talking 685 Billion parameters in a Mixture-of-Experts (MoE) architecture. This isn't R1 (their reasoning model), but the powerful base model that R1 was built upon (and supposedly R2 when it'll come out)The benchmark jumps from the previous version are huge, especially in reasoning:* MMLU-Pro: 75.9 → 81.2 (+5.3)* GPQA: 59.1 → 68.4 (+9.3)* AIME: 39.6 → 59.4 (+19.8) (Almost 20 points on competitive math!)* LiveCodeBench: 39.2 → 49.2 (+10.0)They're highlighting major boosts in reasoning, stronger front-end dev skills, and smarter tool use. Nisten noted it even gets some hard reasoning questions right that challenge other models. The "vibes" are reportedly great. Wolfram tried to run it locally but found even the 1-bit quantized version too large for his system (though it should theoretically fit in combined RAM/VRAM), but he's using it via API. It’s likely the best non-reasoning open model right now, potentially the best overall if you can run it.And huge news for the community – they've released these weights under the MIT License, just like R1! Massive respect to DeepSeek for continuing to push powerful models into the open.They also highlight being significantly better at Front End development and websites aesthetics. Qwen Launches Omni 7B Model - Voice & Video Chat!Our friends at Qwen (Alibaba) also came through with something super cool: Qwen2.5-Omni-7B (HF). This is an end-to-end multimodal model that can perceive text, images, audio, AND video, while generating both text and natural-sounding speech, potentially in real-time.They're using a "Thinker-Talker" architecture. What blew my mind is the size – it's listed as 7B parameters, though I saw a meme suggesting it might be closer to 11B internally (ah, the joys of open source!). Still, even at 11B, having this level of multimodal understanding and generation in a relatively small open model is fantastic. It understands voice and video natively and outputs text and voice. Now, when I hear "Omni," I start expecting image generation too (thanks, Google!), so maybe that's next for Qwen? 😉AI Art & Diffusion & Auto-regressionThis was arguably where the biggest "mainstream" buzz happened this week, thanks mainly to OpenAI.OpenAI Launches Native Image Support in GPT-4o - Ghibli Everywhere!This felt like a direct response to Gemini 2.5's launch, almost like OpenAI saying, "Oh yeah? Watch this!" They finally enabled the native image generation capabilities within GPT-4o (Blog, Examples). Remember that image Greg Brockman tweeted a year ago of someone writing on a blackboard with an old OpenAI logo, hinting at this? Well, it's here.And the results? Honestly, they're stunning. The prompt adherence is incredible. It actually listens to what you ask for in detail, including text generation within images, which diffusion models notoriously struggle with. The realism can be jaw-dropping, but it can also generate various styles.Speaking of styles... the internet immediately lost its collective mind and turned everything into the style of Studio Ghibli (great X thread here). My entire feed became Ghibli-fied. It's a testament to how accessible and fun this feature is. Wolfram even suggested we should have Ghibli avatars for the show!Interestingly, this image generation is apparently auto-regressive, not based on diffusion models like Midjourney or Stable Diffusion. This is more similar to how models like Grok's Aurora work, generating the image sequentially (top-to-bottom, kinda like how old GIFs used to load, as Yam pointed out we confirmed). This likely contributes to the amazing prompt adherence, especially with text.The creative potential is huge – people are generating incredible ad concepts (like this thread) and even recreating entire movie trailers, like this unbelievable Lord of the Rings one (link), purely through prompts in GPT-4o. It's wild.Now, this launch wasn't just about cool features; it also marked a significant shift in OpenAI's policy around image generation, aiming for what CEO Sam Altman called "a new high-water mark for us in allowing creative freedom." Joanne Jang, who leads model behavior at OpenAI, shared some fascinating insights into their thinking (Reservoir Samples post). She explained they're moving away from broad, blanket refusals (which often felt safest but limited creativity) towards a more precise approach focused on preventing real-world harm. This means trusting user creativity more, not letting hypothetical worst-case scenarios overshadow everyday usefulness (like generating memes!), and valuing the "unknown, unimaginable possibilities" that overly strict rules might stifle. It's a nuanced approach acknowledging that, as Joanne quoted, "Ships are safest in the harbor... But that’s not what ships or models are for." A philosophy change I definitely appreciate.Reve - New SOTA Diffusion Contender?While OpenAI grabbed headlines, another player emerged claiming State-of-the-Art results, this time in the diffusion space. Reve Image 1.0 (X, Blog/News, Try it) apparently beats Midjourney and Flux in benchmarks, particularly in prompt adherence, realism, and even text generation (though likely not as consistently as GPT-4o's native approach).It works on a credit system ($5 for 500 generations, ~1 cent per image) which is quite affordable. The editing seems a bit different, relying on chatting with the model rather than complex tools. It was kind of hidden/anonymous before, but now they've revealed themselves. Honestly, this would probably be huge news if OpenAI hadn't dropped their image bomb the same week.Ideogram 3 Also Launched - Another SOTA Claim!And just to make the AI art space even more crowded this week, Ideogram also launched version 3.0 (Blog, Try it), also claiming state-of-the-art performance!Ideogram has always been strong with text rendering and logos. Version 3.0 boasts stunning realism, creative design capabilities, and a new "Style References" feature where you can upload images to guide the aesthetic. They claim it consistently outperforms others in human evaluations. It's wild – we had at least three major image generation models/updates drop this week, all claiming top performance, and none of them seemed to benchmark directly against each other in their launch materials! It’s hard to keep track!This Week's Buzz + MCP (X, Github!)Bringing it back to Weights & Biases for a moment. We had Morgan McQuire on the show, who heads up our AI Applied team, to talk about something we're really excited about internally – integrating MCP with Weave, our LLM observability and evaluation tool. Morgan showed a demo and have shipped the MCP server, which you can try right now!Coming soon is the integration with wandb models, which will allows ML folks around the world to build agents that monitor loss curves for them! Weights & Biases Weave Official MCP Server Tool - Talk to Your Evals!We've launched an official MCP server tool for Weave! What does this mean? If you're using Weave to track your experiments, evaluations, prompts, etc. (and you should be!), you can now literally chat with that data. As Morgan demonstrated, you can ask questions like "Tell me about my last three evaluations," and the MCP tool, connected to your Weave data, will not only fetch and summarize that information for you directly in the chat interface (like Claude code or others that support MCP) but will generate a report and add visualizations! This is just the beginning of how we see MCP enhancing observability and interaction with ML workflows. Being able to query and analyze your runs and evaluations using natural language is incredibly powerful.Agents, Tools & MCPAnd speaking of MCP...OpenAI Adds Support for MCP - MCP WON!This was HUGE news, maybe slightly overshadowed by the image generation, but potentially far more impactful long-term, as Wolfram pointed out right at the start of the show. OpenAI officially announced support for the Model Context Protocol (MCP) (docs here).Why is this massive? Because Anthropic initiated MCP, and there was a real fear that OpenAI, being OpenAI, might just create its own competing standard for agent/tool communication, leading to fragmentation (think VHS vs. Betamax, or Blu-ray vs. HD DVD – standards wars suck!). Instead, OpenAI embraced the existing standard. As I said on the show, MCP WON!This is crucial for the ecosystem. It means developers can build tools and agents using the MCP standard, and they should (hopefully) work seamlessly across different models like Claude and GPT. OpenAI not only added support but released it in their Agents SDK and explicitly stated support is "coming soon" for the ChatGPT desktop app and response APIs. Yam expertly clarified the distinction: tools are often single API calls, while MCPs are servers that can maintain state, allowing for more complex, guided interactions. Qwen also adding MCP support to their UI just reinforces this – the standard is gaining traction fast. This standardization is absolutely essential for building a robust agentic future.Voice & AudioJust one more quick update on the audio front:OpenAI Updates Advanced Voice Mode with Semantic VADAlongside the image generation, OpenAI also quietly updated the advanced voice mode in ChatGPT (YT announcement). The key improvement is "Semantic VAD" (Voice Activity Detection). Instead of just cutting off when you pause (leading to annoying interruptions, especially for kids or people who think while speaking), it now tries to understand the meaning and tone to determine if you're actually finished talking.This should lead to a much more natural conversation flow. They also claim better personality, a more engaging natural tone (direct and concise), and less need for you to fill silence with "umms" just to keep the mic open. It might feel a tad slower because it waits a bit longer, but the improvement in interaction quality should be significant.MLX-AudioAnd speaking (heh) of audio and speech, we had the awesome Prince Canuma on the show! If you're into running models locally on Apple Silicon (Macs!), you probably know Prince. He's the MLX King, the creator and maintainer of essential libraries like MLX-VLM (for vision models), FastMLX, MLX Embeddings, and now, MLX-Audio. Seriously, huge props to Prince and the folks in the MLX community for making these powerful open-source models accessible on Mac hardware. It's an incredible contribution.This week, Prince released MLX-Audio v0.0.3. This isn't just text-to-speech (TTS); it aims to be a comprehensive audio package for MLX. Right now, it supports some of the best open TTS models out there:* Kokoro: The tiny, high-quality TTS model we've covered before.* Sesame 1B: Another strong contender.* Orpheus: From Canopy Labs (as Prince confirmed).* Suno Bark: Known for generating music and sound effects too.MLX-Audio makes running state-of-the-art speech synthesis locally on your Mac incredibly easy, basically offering a Hugging Face transformers pipeline equivalent but optimized for Apple Silicon. If you have a Mac, pip install mlx-audio and give it a spin! Prince also took a feature request on the show to allow text file input directly, so look out for that!Phew! See what I mean? An absolutely jam-packed week. Huge thanks again to Tulsee, Morgan, and Prince for joining us and sharing their insights, and to Wolfram, Nisten, and Yam for co-piloting through the news storm. And thank YOU all for tuning in! We'll be back next week, undoubtedly trying to catch our breath and make sense of whatever AI marvels (or madness) gets unleashed next.

Hey, it's Alex, coming to you fresh off another live recording of ThursdAI, and what an incredible one it's been! I was hoping that this week will be chill with the releases, because of NVIDIA's GTC conference, but no, the AI world doesn't stop, and if you blinked this week, you may have missed 2 or 10 major things that happened. From Mistral coming back to OSS with the amazing Mistral Small 3.1 (beating Gemma from last week!) to OpenAI dropping a new voice generation model, and 2! new whisper killer ASR models with a Breaking News during our live show (there's a reason we're called ThursdAI) which we watched together and then dissected with Kwindla, our amazing AI VOICE and real time expert. Not to mention that we also had dedicated breaking news from friend of the pod Joseph Nelson, that came on the show to announce a SOTA vision model from Roboflow + a new benchmark on which even the top VL models get around 6%! There's also a bunch of other OSS, a SOTA 3d model from Tencent and more! And last but not least, Yam is back 🎉 So... buckle up and let's dive in. As always, TL;DR and show notes at the end, and here's the YT live version. (While you're there, please hit subscribe and help me hit that 1K subs on YT 🙏 )Voice & Audio: OpenAI's Voice Revolution and the Open Source EchoHold the phone, everyone, because this week belonged to Voice & Audio! Seriously, if you weren't paying attention to the voice space, you missed a seismic shift, courtesy of OpenAI and some serious open-source contenders.OpenAI's New Voice Models - Whisper Gets an Upgrade, TTS Gets Emotional!OpenAI dropped a suite of next-gen audio models: gpt-4o-mini-tts-latest (text-to-speech) and GPT 4.0 Transcribe and GPT 4.0 Mini Transcribe (speech-to-text), all built upon their powerful transformer architecture.To unpack this voice revolution, we welcomed back Kwindla Cramer from Daily, the voice AI whisperer himself. The headline news? The new speech-to-text models are not just incremental improvements; they’re a whole new ballgame. As OpenAI’s Shenyi explained, "Our new generation model is based on our large speech model. This means this new model has been trained on trillions of audio tokens." They're faster, cheaper (Mini Transcribe is half price of Whisper!), and boast state-of-the-art accuracy across multiple languages. But the real kicker? They're promptable!"This basically opens up a whole field of prompt engineering for these models, which is crazy," I exclaimed, my mind officially blown. Imagine prompting your transcription model with context – telling it you're discussing dog breeds, and suddenly, its accuracy for breed names skyrockets. That's the power of promptable ASR! I recorded a live reaction aftder dropping of stream, and I was really impressed with how I can get the models to pronounce ThursdAI by just... asking! But the voice magic doesn't stop there. GPT 4.0 Mini TTS, the new text-to-speech model, can now be prompted for… emotions! "You can prompt to be emotional. You can ask it to do some stuff. You can prompt the character a voice," OpenAI even demoed a "Mad Scientist" voice! Captain Ryland voice, anyone? This is a huge leap forward in TTS, making AI voices sound… well, more human.But wait, there’s more! Semantic VAD! Semantic Voice Activity Detection, as OpenAI explained, "chunks the audio up based on when the model thinks The user's actually finished speaking." It’s about understanding the meaning of speech, not just detecting silence. Kwindla hailed it as "a big step forward," finally addressing the age-old problem of AI agents interrupting you mid-thought. No more robotic impatience!OpenAI also threw in noise reduction and conversation item retrieval, making these new voice models production-ready powerhouses. This isn't just an update; it's a voice AI revolution, folks.They also built a super nice website to test out the new models with openai.fm ! Canopy Labs' Orpheus 3B - Open Source Voice Steps UpBut hold on, the open-source voice community isn't about to be outshone! Canopy Labs dropped Orpheus 3B, a "natural sounding speech language model" with open-source spirit. Orpheus, available in multiple sizes (3B, 1B, 500M, 150M), boasts zero-shot voice cloning and a glorious Apache 2 license. Wolfram noted its current lack of multilingual support, but remained enthusiastic, I played with them a bit and they do sound quite awesome, but I wasn't able to finetune them on my own voice due to "CUDA OUT OF MEMORY" alasI did a live reaction recording for this model on XNVIDIA Canary - Open Source Speech Recognition Enters the RaceSpeaking of open source, NVIDIA surprised us with Canary, a speech recognition and translation model. "NVIDIA open sourced Canary, which is a 1 billion parameter and 180 million parameter speech recognition and translation, so basically like whisper competitor," I summarized. Canary is tiny, fast, and CC-BY licensed, allowing commercial use. It even snagged second place on the Hugging Face speech recognition leaderboard! Open source ASR just got a whole lot more interesting.Of course, this won't get to the level of the new SOTA ASR OpenAI just dropped, but this can run locally and allows commercial use on edge devices!

We were lucky enough to have Joseph Nelson, Roboflow CEO, join the show again and give us the breaking news (they published the Github 11 minutes before he came on!) RF-DETR is Roboflow's first in-house model, a real-time object detection transformer that's rewriting the rulebook. "We've actually never released a model that we've developed. And so this is the first time where we've taken a lot of those learnings and put that into a model," Joseph revealed.And what a model it is! RF-DETR is not just fast; it's SOTA on real-world datasets and surpasses the 60 mAP barrier on COCO. But Joseph dropped a truth bomb: COCO is outdated. "The benchmark that everyone uses is, the COCO benchmark… hasn't been updated since 2017, but models have continued to get really, really, really good. And so they're saturated the COCO benchmark," he explained.Enter RF100-VL, Roboflow's revolutionary new benchmark, designed to evaluate vision-language models on real-world data. "We, introduced a benchmark that we call RF 100 vision language," Joseph announced. The results? Shockingly low zero-shot performance on real-world vision tasks, highlighting a major gap in current models. Joseph's quiz question about QwenVL 2.5's zero-shot performance on RF100-VL revealed a dismal 5.8% accuracy. "So we as a field have a long, long way to go before we have zero shot performance on real world context," Joseph concluded. RF100-VL is the new frontier for vision, and RF-DETR is leading the charge! Plus, it runs on edge devices and is Apache 2 licensed! Roboflow, you legends! Check out the RF-DETR Blog Post, the RF-DETR Github, and the RF100-VL Benchmark for more details!StepFun's Image-to-Video TI2V - Animating Images with StyleStepping into the video arena, StepFun released their image2video model, TI2V. TI2V boasts impressive motion controls and generates high-quality videos from images and text prompts, especially excelling in anime-style video generation. Dive into the TI2V HuggingFace Space and TI2V Github to explore further.Open Source LLMs: Mistral's Triumphant Return, LG's Fridge LLM, NVIDIA's Nemotron, and ByteDance's RL BoostLet's circle back to our beloved Open Source LLMs, where this week was nothing short of a gold rush!Mistral is BACK, Baby! - Mistral Small 3.1 24B (Again!)Seriously, Mistral AI's return to open source with Mistral Small 3.1 deserves another shoutout! "Mistral is back with open source. Let's go!" I cheered, and I meant it. This multimodal, Apache 2 licensed model is a powerhouse, outperforming Gemma 3 and ready for action on a single GPU. Wolfram, ever the pragmatist, noted, "We are in right now, where a week later, you already have some new toys to play with." referring to Gemma 3 that we covered just last week! Not only did we get a great new update from Mistral, they also cited our friends at Nous research and their Deep Hermes (released just last week!) for the reason to release the base models alongside finetuned models! Mistral Small 3.1 is not just a model; it's a statement: open source is thriving, and Mistral is leading the charge! Check out their Blog Post, the HuggingFace page, and the Base Model on HF. NVIDIA Nemotron - Distilling, Pruning, Making Llama's BetterNVIDIA finally dropped Llama Nemotron, and it was worth the wait! Nemotron Nano (8B) and Super (49B) are here, with Ultra (253B) on the horizon. These models are distilled, pruned, and, crucially, designed for reasoning with a hybrid architecture allowing you to enable and disable reasoning via a simple on/off switch in the system prompt! Beating other reasoners like QwQ on GPQA tasks, this distillined and pruned LLama based reasoner seems very powerful! Congrats to NVIDIAChris Alexius (a friend of the pod) who co-authored the announcement, told me that FP8 is expected and when that drops, this model will also fit on a single H100 GPU, making it really great for enterprises who host on their own hardware. And yes, it’s ready for commercial use. NVIDIA, welcome to the open-source LLM party! Explore the Llama-Nemotron HuggingFace Collection and the Dataset.LG Enters the LLM Fray with EXAONE Deep 32B - Fridge AI is Officially a ThingLG, yes, that LG, surprised everyone by open-sourcing EXAONE Deep 32B, a "thinking model" from the fridge and TV giant. "LG open sources EXAONE and EXAONE Deep 32B thinking model," I announced, still slightly amused by the fridge-LLM concept. This 32B parameter model claims "superior capabilities" in reasoning, and while my live test in LM Studio went a bit haywire, quantization could be the culprit. It's non-commercial, but hey, fridge-powered AI is now officially a thing. Who saw that coming? Check out my Reaction Video, the LG Blog, and the HuggingFace page for more info.ByteDance's DAPO - Reinforcement Learning Gets EfficientFrom the creators of TikTok, ByteDance, comes DAPO, a new reinforcement learning method that's outperforming GRPO. DAPO promises 50% accuracy on AIME 2024 with 50% less training steps. Nisten, our RL expert, explained it's a refined GRPO, pushing the boundaries of RL efficiency. Open source RL is getting faster and better, thanks to ByteDance! Dive into the X thread, Github, and Paper for the technical details.Big CO LLMs + APIs: Google's Generosity, OpenAI's Oligarch Pricing, and GTC ManiaSwitching gears to the Big CO LLM arena, we saw Google making moves for the masses, OpenAI catering to the elite, and NVIDIA… well, being NVIDIA.Google Makes DeepResearch Free and Adds CanvasGoogle is opening up DeepResearch to everyone for FREE! DeepResearch, Gemini's advanced search mode, is now accessible without a Pro subscription. I really like it's revamped UI where you can see the thinking and the sources! I used it live on the show to find out what we talked about in the latest episode of ThursdAI, and it did a pretty good job! Plus, Google unveiled Canvas, letting you "build apps within Gemini and actually see them." Google is making Gemini more accessible and more powerful, a win for everyone. Here's a Tetris game it built for me and here's a markdown enabled word counter I rebuild every week before I send ThursdAI (making sure I don't send you 10K words every week 😅)OpenAI's O1 Pro API - Pricey Power for the FewOpenAI, in contrast, released O1 Pro API, but with a price tag that's… astronomical. "OpenAI makes O1-pro API available to oligarchs ($600/1mtok output!)," I quipped, highlighting the exclusivity. $600 per million output tokens? "If you code with this, if you vibe code with this, you better already have VCs backing your startup," I warned. O1 Pro might be top-tier performance, but it's priced for the 0.1%.NVIDIA GTC Recap - Jensen's Hardware ExtravaganzaNVIDIA GTC was, as always, a hardware spectacle. New GPUs (Blackwell Ultra, Vera Rubin, Feynman!), the tiny DGX Spark supercomputer, the GR00T robot foundation model, and the Blue robot – NVIDIA is building the AI future, brick by silicon brick. Jensen is the AI world's rockstar, and GTC is his sold-out stadium show. Check out Rowan Cheung's GTC Recap on X for a quick overview.Shoutout to our team at GTC and this amazingly timed logo shot I took from the live stream! Antropic adds Web SearchWe had a surprise at the end of the show, with Antropic releasing web search. It's a small thing, but for folks who use Cloud AI, it's very important.You can now turn on web search directly on Claude which makes it... the last frontier lab to enable this feature 😂 Congrats! AI Art & Diffusion & 3D: Tencent's 3D RevolutionTencent Hunyuan 3D 2.0 MV and Turbo - 3D Generation Gets Real-TimeTencent updated Hunyuan 3D to 2.0 MV (MultiView) and Turbo, pushing the boundaries of 3D generation. Hunyuan 3D 2.0 surpasses SOTA in geometry, texture, and alignment, and the Turbo version achieves near real-time 3D generation – under one second on an H100! Try out the Hunyuan3D-2mv HF Space to generate your own 3D masterpieces! MultiView (MV) is another game-changer, allowing you to input 1-4 views for more accurate 3D models. "MV allows to generate 3d shapes from 1-4 views making the 3D shapes much higher quality" I explained. The demo of generating a 3D mouse from Gemini-generated images showcased the seamless pipeline from thought to 3D object. I literally just asked Gemini with native image generation to generate a character and then Holodecks are getting closer, folks!Closing Remarks and Thank YouAnd that's all she wrote, folks! Another week, another AI explosion. From voice to vision, open source to Big CO, this week was a whirlwind of innovation. Huge thanks again to our incredible guests, Joseph Nelson from Roboflow, Kwindla Cramer from Daily, and Lucas Atkins from ARCEE! And of course, massive shoutout to my co-hosts, Wolfram, Yam, and Nisten – you guys are the best!And YOU, the ThursdAI community, are the reason we do this.

LET'S GO! Happy second birthday to ThursdAI, your favorite weekly AI news show! Can you believe it's been two whole years since we jumped into that random Twitter Space to rant about GPT-4? From humble beginnings as a late-night Twitter chat to a full-blown podcast, Newsletter and YouTube show with hundreds of thousands of downloads, it's been an absolutely wild ride! That's right, two whole years of me, Alex Volkov, your friendly AI Evangelist, along with my amazing co-hosts, trying to keep you up-to-date on the breakneck speed of the AI worldAnd what better way to celebrate than with a week PACKED with insane AI news? Buckle up, folks, because this week Google went OPEN SOURCE crazy, Gemini got even cooler, OpenAI created a whole new Agents SDK and the open-source community continues to blow our minds. We’ve got it all - from game-changing model releases to mind-bending demos.This week I'm also on the Weights & Biases company retreat, so TL;DR first and then the newsletter, but honestly, I'll start embedding the live show here in the substack from now on, because we're getting so good at it, I barely have to edit lately and there's a LOT to show you guys!

Google dropped a BOMBSHELL with Gemma 3! As Wolfram pointed out, this is a "very technical achievement," and it's not just one model, but a whole family ranging from 1 billion to 27 billion parameters. And get this – the 27B model can run on a SINGLE GPU! Sundar Pichai himself claimed you’d need "at least 10X compute to get similar performance from other models." Insane!Gemma 3 isn't just about size; it's packed with features. We're talking multimodal capabilities (text, images, and video!), support for over 140 languages, and a massive 128k context window. As Nisten pointed out, "it might actually end up being the best at multimodal in that regard" for local models. Plus, it's fine-tuned for safety and comes with ShieldGemma 2 for content moderation. You can grab Gemma 3 on Google AI Studio, Hugging Face, Ollama, Kaggle – everywhere! Huge shoutout to Omar Sanseviero and the Google team for this incredible release and for supporting the open-source community from day one! Colin aka Bartowski, was right, "The best thing about Gemma is the fact that Google specifically helped the open source communities to get day one support." This is how you do open source right!Next up, we have EuroBERT, a new family of multilingual encoder models. Wolfram, our European representative, was particularly excited about this one: "In European languages, you have different characters than in other languages. And, um, yeah, encoding everything properly is, uh, difficult." Ranging from 210 million to 2.1 billion parameters, EuroBERT is designed to push the boundaries of NLP in European and global languages. With training on a massive 5 trillion-token dataset across 15 languages and support for 8K context tokens, EuroBERT is a workhorse for RAG and other NLP tasks. Plus, how cool is their mascot?Reka Flash 3 - a 21B reasoner with apache 2 trained with RLOOAnd the open source train keeps rolling! Reka AI dropped Reka Flash 3, a 21 billion parameter reasoning model with an Apache 2.0 license! Nisten was blown away by the benchmarks: "This might be one of the best like 20B size models that there is right now. And it's Apache 2.0. Uh, I, I think this is a much bigger deal than most people realize." Reka Flash 3 is compact, efficient, and excels at chat, coding, instruction following, and function calling. They even used a new reinforcement learning technique called REINFORCE Leave One-Out (RLOO). Go give it a whirl on Hugging Face or their chat interface – chat.reka.ai!Last but definitely not least in the open-source realm, we had a special guest, Sandra (@itsSandraKublik) from Cohere, join us to announce Command-A! This beast of a model clocks in at 111 BILLION parameters with a massive 256K context window. Sandra emphasized its efficiency, "It requires only two GPUs. Typically the models of this size require 32 GPUs. So it's a huge, huge difference." Command-A is designed for enterprises, focusing on agentic tasks, tool use, and multilingual performance. It's optimized for private deployments and boasts enterprise-grade security. Congrats to Sandra and the Cohere team on this massive release!Big CO LLMs + APIs: Gemini Flash Gets Visual, Deep Research Goes Free, and OpenAI Builds for AgentsThe big companies weren't sleeping either! Google continued their awesome week by unleashing native image generation in Gemini Flash Experimental! This is seriously f*****g cool, folks! Sorry for my French, but it’s true. You can now directly interact with images, tell Gemini what to do, and it just does it. We even showed it live on the stream, turning ourselves into cat-confetti-birthday-hat-wearing masterpieces! Wolfram was right, "It's also a sign what we will see in, like, Photoshop, for example. Where you, you expect to just talk to it and have it do everything that a graphic designer would be doing." The future of creative tools is HERE.And guess what else Google did? They made Deep Research FREE in the Gemini app and powered by Gemini Thinking! Nisten jumped in to test it live, and we were all impressed. "This is the nicest interface so far that I've seen," he said. Deep Research now digs through HUNDREDS of websites (Nisten’s test hit 156!) to give you comprehensive answers, and the interface is slick and user-friendly. Plus, you can export to Google Docs! Intelligence too cheap to meter? Google is definitely pushing that boundary.Last second additions - Allen Institute for AI released OLMo 2 32B - their biggest open model yetJust as I'm writing this, friend of the pod, Nathan from Allen Institute for AI announced the release of a FULLY OPEN OLMo 2, which includes weights, code, dataset, everything and apparently it beats the latest GPT 3.5, GPT 4o mini, and leading open weight models like Qwen and Mistral. Evals look legit, but nore than that, this is an Apache 2 model with everything in place to advance open AI and open science! Check out Nathans tweet for more info, and congrats to Allen team for this awesome release! OpenAI new responses API and Agent ASK with Web, File and CUA toolsOf course, OpenAI wasn't going to let Google have all the fun. They dropped a new SDK for agents called the Responses API. This is a whole new way to build with OpenAI, designed specifically for the agentic era we're entering. They also released three new tools: Web Search, Computer Use Tool, and File Search Tool. The Web Search tool is self-explanatory – finally, built-in web search from OpenAI!The Computer Use Tool, while currently limited in availability, opens up exciting possibilities for agent automation, letting agents interact with computer interfaces. And the File Search Tool gives you a built-in RAG system, simplifying knowledge retrieval from your own files. As always, OpenAI is adapting to the agentic world and giving developers more power.Finally in the big company space, Nous Research released PORTAL, their new Inference API service. Now you can access their awesome models, like Hermes 3 Llama 70B and DeepHermes 3 8B, directly via API. It's great to see more open-source labs offering API access, making these powerful models even more accessible.This Week's Buzz at Weights & Biases: Offsite Hackathon and MCP Mania!This week's "This Week's Buzz" segment comes to you live from Oceanside, California! The whole Weights & Biases team is here for our company offsite. Despite the not-so-sunny California weather (thanks, storm!), it's been an incredible week of meeting colleagues, strategizing, and HACKING!And speaking of hacking, we had an MCP hackathon! After last week’s MCP-pilling episode, we were all hyped about Model Context Protocol, and the team didn't disappoint. In just three hours, the innovation was flowing! We saw agents built for WordPress, MCP support integrated into Weave playground, and even MCP servers for Weights & Biases itself! Get ready, folks, because an MCP server for Weights & Biases is COMING SOON! You'll be able to talk to your W&B data like never before. Huge shoutout to the W&B team for their incredible talent and for embracing the agentic future! And in case you missed it, Weights & Biases is now part of the CoreWeave family! Exciting times ahead!Vision & Video: LoRA Video Effects and OpenSora 2.0Moving into vision and video, Remade AI released 8 LoRA video effects for 1X! Remember 1X from Alibaba? Now you can add crazy effects like "squish," "inflate," "deflate," and even "cakeify" to your videos using LoRAs. It's open source and super cool to see video effects becoming trainable and customizable.And in the realm of open-source video generation, OpenSora 2.0 dropped! This 11 billion parameter model claims state-of-the-art video generation trained for just $200,000! They’re even claiming performance close to Sora itself on some benchmarks. Nisten checked out the demos, and while we're all a bit jaded now with the rapid pace of video AI, it's still mind-blowing how far we've come. Open source video is getting seriously impressive, seriously fast.AI Art & Diffusion & 3D: ByteDance's Bilingual Seedream 2.0ByteDance, the folks behind TikTok, released Seedream 2.0, a native Chinese-English bilingual image generation foundation model. This model, from ByteDream, excels at text rendering, cultural nuance, and human preference alignment. Seedream 2.0 boasts "powerful general capability," "native bilingual comprehension ability," and "excellent text rendering." It's designed to understand both Chinese and English prompts natively, generating high-quality, culturally relevant images. The examples look stunning, especially its ability to render Chinese text beautifully.Tools: Manus AI Agent, Google AI Studio YouTube Links, and Cursor EmbeddingsFinally, in the tools section, everyone's buzzing about Manus, a new AI research agent. We gave it a try live on the show, asking it to do some research. The UI is slick, and it seems to be using Claude 3.7 behind the scenes. Manus creates a to-do list, browses the web in a real Chrome browser, and even generates files. It's like Operator on steroids. We'll be keeping an eye on Manus and will report back on its performance in future episodes.And Google AI Studio keeps getting better! Now you can drop YouTube links into Google AI Studio, and it will natively understand the video! This is HUGE for video analysis and content understanding. Imagine using this for support, content summarization, and so much more.PHEW! What a week to celebrate two years of ThursdAI! From open source explosions to Gemini's visual prowess and OpenAI's agentic advancements, the AI world is moving faster than ever. As Wolfram aptly put it, "The acceleration, you can feel it." And Nisten reminded us of the incredible journey, "I remember I had early access to GPT-4 32K, and, uh, then... the person for the contract that had given me access, they cut it off because on the one weekend, I didn't realize how expensive it was. So I had to use $180 worth of tokens just trying it out." Now, we have models that are more powerful and more accessible than ever before. Thank you to Wolfram, Nisten, and LDJ for co-hosting and bringing their insights every week. And most importantly, THANK YOU to our amazing community for tuning in, listening, and supporting ThursdAI for two incredible years! We couldn't do it without you. Here's to another year of staying up-to-date so YOU don't have to! Don't forget to subscribe to the podcast, YouTube channel, and newsletter to stay in the loop. And share ThursdAI with a friend – it's the best birthday gift you can give us! Until next week, keep building and keep exploring the amazing world of AI! LET'S GO! This is a public episode.

What is UP folks! Alex here from Weights & Biases (yeah, still, but check this weeks buzz section below for some news!) I really really enjoyed today's episode, I feel like I can post it unedited it was so so good. We started the show with our good friend Junyang Lin from Alibaba Qwen, where he told us about their new 32B reasoner QwQ. Then we interviewed Google's VP of the search product, Robby Stein, who came and told us about their upcoming AI mode in Google! I got access and played with it, and it made me switch back from PPXL as my main. And lastly, I recently became fully MCP-pilled, since we covered it when it came out over thanksgiving, I saw this acronym everywhere on my timeline but only recently "got it" and so I wanted to have an MCP deep dive, and boy... did I get what I wished for! You absolutely should tune in to the show as there's no way for me to cover everything we covered about MCP with Dina and Jason! ok without, further adieu.. let's dive in (and the TL;DR, links and show notes in the end as always!) ThursdAI - Recaps of the most high signal AI weekly spaces is a reader-supported publication. To receive new posts and support my work, consider becoming a free or paid subscriber.🤯 Alibaba's QwQ-32B: Small But Shocking Everyone!The open-source LLM segment started strong, chatting with friend of the show Junyang Justin Lin from Alibaba’s esteemed Qwen team. They've cooked up something quite special: QwQ-32B, a reasoning-focused, reinforcement-learning-boosted beast that punches remarkably above its weight. We're talking about a mere 32B parameters model holding its ground on tough evaluations against DeepSeek R1, a 671B behemoth!Here’s how wild this is: You can literally run QwQ on your Mac! Junyang shared that they applied two solid rounds of RL to amp its reasoning, coding, and math capabilities, integrating agents into the model to fully unlock its abilities. When I called out how insane it was that we’ve gone from "LLMs can't do math" to basically acing competitive math benchmarks like AIME24, Junyang calmly hinted that they're already aiming for unified thinking/non-thinking models. Sounds wild, doesn’t it?Check out the full QwQ release here, or dive into their blog post.🚀 Google Launches AI Mode: Search Goes Next-Level (X, Blog, My Live Reaction).For the past two years, on this very show, we've been asking, "Where's Google?" in the Gen AI race. Well, folks, they're back. And they're back in a big way.Next, we were thrilled to have Google’s own Robby Stein, VP of Product for Google Search, drop by ThursdAI after their massive launch of AI Mode and expanded AI Overviews leveraging Gemini 2.0. Robby walked us through this massive shift, which essentially brings advanced conversational AI capabilities straight into Google. Seriously — Gemini 2.0 is now out here doing complex reasoning while performing fan-out queries behind the scenes in Google's infrastructure.Google search is literally Googling itself. No joke. "We actually have the model generating fan-out queries — Google searches within searches — to collect accurate, fresh, and verified data," explained Robby during our chat. And I gotta admit, after playing with AI Mode, Google is definitely back in the game—real-time restaurant closures, stock analyses, product comparisons, and it’s conversational to boot. You can check my blind reaction first impression video here. (also, while you're there, why not subscribe to my YT?)Google has some huge plans, but right now AI Mode is rolling out slowly via Google Labs for Google One AI Premium subscribers first. More soon though!🐝 This Week's Buzz: Weights & Biases Joins CoreWeave Family!Huge buzz (in every sense of the word) from Weights & Biases, who made waves with their announcement this week: We've joined forces with CoreWeave! Yeah, that's big news as CoreWeave, the AI hyperscaler known for delivering critical AI infrastructure, has now acquired Weights & Biases to build the ultimate end-to-end AI platform. It's early days of this exciting journey, and more details are emerging, but safe to say: the future of Weights & Biases just got even more exciting. Congrats to the whole team at Weights & Biases and our new colleagues at CoreWeave!We're committed to all users of WandB so you will be able to keep using Weights & Biases, and we'll continuously improve our offerings going forward! Personally, also nothing changes for ThursdAI! 🎉MCP Takes Over: Giving AI agents super powers via standardized protocol Then things got insanely exciting. Why? Because MCP is blowing up and I had to find out why everyone's timeline (mine included) just got invaded.Welcoming Cloudflare’s amazing product manager Dina Kozlov and Jason Kneen—MCP master and creator—things quickly got mind-blowing. MCP servers, Jason explained, are essentially tool wrappers that effortlessly empower agents with capabilities like API access and even calling other LLMs—completely seamlessly and securely. According to Jason, "we haven't even touched the surface yet of what MCP can do—these things are Lego bricks ready to form swarms and even self-evolve."Dina broke down just how easy it is to launch MCP servers on Cloudflare Workers while teasing exciting upcoming enhancements. Both Dina and Jason shared jaw-dropping examples, including composing complex workflows connecting Git, Jira, Gmail, and even smart home controls—practically instantaneously! Seriously, my mind is still spinning.The MCP train is picking up steam, and something tells me we'll be talking about this revolutionary agent technology a lot more soon. Check out two great MCP directories that popped up this recently: Smithery, Cursor Directory and Composio.This show was one of the best ones we recorded, honestly, I barely need to edit it. It was also a really really fun livestream, so if you prefer seeing to listening, here's the lightly edited live streamThank you for being a ThursdAI subscriber, as always here's the TL:DR and shownotes for everything that happened in AI this week and the things we mentioned (and hosts we had)ThursdAI - Recaps of the most high signal AI weekly spaces is a reader-supported publication.

Hey all, Alex here 👋What can I say, the weeks are getting busier , and this is one of those "crazy full" weeks in AI. As we were about to start recording, OpenAI teased GPT 4.5 live stream, and we already had a very busy show lined up (Claude 3.7 vibes are immaculate, Grok got an unhinged voice mode) and I had an interview with Kevin Hou from Windsurf scheduled! Let's dive in! 🔥 GPT 4.5 (ORION) is here - worlds largest LLM (10x GPT4o) OpenAI has finally shipped their next .5 model, which is 10x scale from the previous model. We didn't cover this on the podcast but did watch the OpenAI live stream together after the podcast concluded. A very interesting .5 release from OpenAI, where even Sam Altman says "this model won't crush on benchmarks" and is not the most frontier model, but is OpenAI's LARGEST model by far (folks are speculating 10+ Trillions of parameters) After 2 years of smaller models and distillations, we finally got a new BIG model, that shows scaling laws proper, and while on some benchmarks it won't compete against reasoning models, this model will absolutely fuel a huge increase in capabilities even for reasoners, once o-series models will be trained on top of this. Here's a summary of the announcement and quick vibes recap (from folks who had access to it before) * OpenAI's largest, most knowledgeable model.* Increased world knowledge: 62.5% on SimpleQA, 71.4% GPQA* Better in creative writing, programming, problem-solving (no native step-by-step reasoning).* Text and image input and text output* Available in ChatGPT Pro and API access (API supports Function Calling, Structured Output)* Knowledge Cutoff is October 2023.* Context Window is 128,000 tokens.* Max Output is 16,384 tokens.* Pricing (per 1M tokens): Input: $75, Output: $150, Cached Input: $37.50.* Foundation for future reasoning models4.5 Vibes RecapTons of folks who had access are pointing to the same thing, while this model is not beating others on evals, it's much better at multiple other things, namely creative writing, recommending songs, improved vision capability and improved medical diagnosis. Karpathy said "Everything is a little bit better and it's awesome, but also not exactly in ways that are trivial to point to" and posted a thread of pairwise comparisons of tone on his X threadThough the reaction is bifurcated as many are upset with the high price of this model (10x more costly on outputs) and the fact that it's just marginally better at coding tasks. Compared to the newerSonnet (Sonnet 3.7) and DeepSeek, folks are looking at OpenAI and asking, why isn't this way better? Anthropic's Claude 3.7 Sonnet: A Coding PowerhouseAnthropic released Claude 3.7 Sonnet, and the immediate reaction from the community was overwhelmingly positive. With 8x more output capability (64K) and reasoning built in, this model is an absolute coding powerhouse. Claude 3.7 Sonnet is the new king of coding models, achieving a remarkable 70% on the challenging SWE-Bench benchmark, and the initial user feedback is stellar, though vibes started to shift a bit towards Thursday.Ranking #1 on WebDev arena, and seemingly trained on UX and websites, Claude Sonnet 3.7 (AKA NewerSonner) has been blowing our collective minds since it was released on Monday, especially due to introducing Thinking and reasoning in a combined model. Now, since the start of the week, the community actually had time to play with it, and some of them return to sonnet 3.5 and saying that while the model is generally much more capable, it tends to generate tons of things that are unnecessary. I wonder if the shift is due to Cursor/Windsurf specific prompts, or the model's larger output context, and we'll keep you updated on if the vibes shift again. Open Source LLMsThis week was HUGE for open source, folks. We saw releases pushing the boundaries of speed, multimodality, and even the very way LLMs generate text!DeepSeek's Open Source SpreeDeepSeek went on an absolute tear, open-sourcing a treasure trove of advanced tools and techniques:This isn't your average open-source dump, folks. We're talking FlashMLA (efficient decoding on Hopper GPUs), DeepEP (an optimized communication library for MoE models), DeepGEMM (an FP8 GEMM library that's apparently ridiculously fast), and even parallelism strategies like DualPipe and EPLB.They are releasing some advanced stuff for training and optimization of LLMs, you can follow all their releases on their X accountDual Pipe seems to be the one that got most attention from the community, which is an incredible feat in pipe parallelism, that even got the cofounder of HuggingFace super excitedMicrosoft's Phi-4: Multimodal and Mini (Blog, HuggingFace)Microsoft joined the party with Phi-4-multimodal (5.6B parameters) and Phi-4-mini (3.8B parameters), showing that small models can pack a serious punch.These models are a big deal. Phi-4-multimodal can process text, images, and audio, and it actually beats WhisperV3 on transcription! As Nisten said, "This is a new model and, I'm still reserving judgment until, until I tried it, but it looks ideal for, for a portable size that you can run on the phone and it's multimodal." It even supports a wide range of languages. Phi-4-mini, on the other hand, is all about speed and efficiency, perfect for finetuning.Diffusion LLMs: Mercury Coder and LLaDA (X , Try it)This is where things get really interesting. We saw not one, but two diffusion-based LLMs this week: Mercury Coder from Inception Labs and LLaDA 8B. (Although, ok, to be fair, LLaDa released 2 weeks ago I was just busy)For those who don't know, diffusion is usually used for creating things like images. The idea of using it to generate text is like saying, "Okay, there's a revolutionary tool for painting; I'll write the code using it." Inception Labs' Mercury Coder is claiming over 1000 tokens per second on NVIDIA H100s – that's insane speed, usually only seen with specialized chips! Nisten spent hours digging into these, noting, "This is a complete breakthrough and, it just hasn't quite hit yet that this just happened because people thought for a while it should be possible because then you can do, you can do multiple token prediction at once". He explained that these models combine a regular LLM with a diffusion component, allowing them to generate multiple tokens simultaneously and excel at tasks like "fill in the middle" coding.LLaDA 8B, on the other hand, is an open-source attempt, and while it needs more training, it shows the potential of this approach. LDJ pointed out that LLaDA is "trained on like around five times or seven times less data while already like competing with LLAMA3 AP with same parameter count".Are diffusion LLMs the future? It's too early to say, but the speed gains are very intriguing.Magma 8B: Robotics LLM from MicrosoftMicrosoft dropped Magma 8B, a Microsoft Research project, an open-source model that combines vision and language understanding with the ability to control robotic actions.Nisten was particularly hyped about this one, calling it "the robotics. LLM." He sees it as a potential game-changer for robotics companies, allowing them to build robots that can understand visual input, respond to language commands, and act in the real world.OpenAI's Deep Research for Everyone (Well, Plus Subscribers)OpenAI finally brought Deep Research, its incredible web-browsing and research tool, to Plus subscribers.I've been saying this for a while: Deep Research is another ChatGPT moment. It's that good. It goes out, visits websites, understands your query in context, and synthesizes information like nothing else. As Nisten put it, "Nothing comes close to OpenAI's Deep Research...People like pull actual economics data, pull actual stuff." If you haven't tried it, you absolutely should.Our full coverage of Deep Research is here if you haven't yet listened, it's incredible. Alexa Gets an AI Brain Upgrade with Alexa+Amazon finally announced Alexa+, the long-awaited LLM-powered upgrade to its ubiquitous voice assistant.Alexa+ will be powered by Claude (and sometimes Nova), offering a much more conversational and intelligent experience, with integrations across Amazon services.This is a huge deal. For years, Alexa has felt… well, dumb, compared to the advancements in LLMs. Now, it's getting a serious intelligence boost, thanks to Anthropic's Claude. It'll be able to handle complex conversations, control smart home devices, and even perform tasks across various Amazon services. Imagine asking Alexa, "Did I let the dog out today?" and it actually checking your Ring camera footage to give you an answer! (Although, as I joked, let's hope it doesn't start setting houses on fire.)Also very intriguing is the new SDKs they are releasing to connect Alexa+ to all kinds of experience, I think this is huge and will absolutely create a new industry of applications built for voice Alexa. Alexa Web Actions for example will allow Alexa to navigate to a website and complete actions (think order Uber Eats) The price? 20$/mo but free if you're a Amazon Prime subscriber, which is most of the US households at this point. They are focusing on personalization and memory, though still unclear how that's going to be handled, and the ability to share documents like schedules I'm very much looking forward to smart Alexa, and to be able to say "Alexa, set a timer for the amount of time it takes to hard boil an egg, and flash my house lights when the timer is done" Grok Gets a Voice... and It's UNHINGEDGrok, Elon Musk's AI, finally got a voice mode, and… well, it's something else.One-sentence summary: Grok's new voice mode includes an "unhinged" 18+ option that curses like a sailor, along with other personality settings.Yes, you read that right. There's literally an "unhinged" setting in the UI. We played it live on the show, and... well, let's just say it's not for the faint of heart (or for kids). Here's a taste:Alex: "Hey there."Grok: "Yo, Alex. What's good, you horny b*****d? How's your day been so far? Fucked up or just mildly shitty?"Beyond the shock value, the voice mode is actually quite impressive in its expressiveness and ability to understand interruptions. It has several personalities, from a helpful "Grok Doc" to an "argumentative" mode that will disagree with everything you say. It's... unique.This Week's Buzz (WandB-Related News)Agents Course is Coming!We announced our upcoming agents course! You can pre-sign up HERE . This is going to be a deep dive into building and deploying AI agents, so don't miss it!AI Engineer Summit RecapWe briefly touched on the AI Engineer Summit in New York, where we met with Kevin Hou and many other brilliant minds in the AI space. The theme was "Agents at Work," and it was a fantastic opportunity to see the latest developments in agent technology. I gave a talk about reasoning agents and had a workshop about evaluations on Saturday, and saw many listeners of ThursdAI 👏 ✋ Interview with Kevin Hou from WindsurfThis week we had the pleasure of chatting with Kevin Hou from Windsurf about their revolutionary AI editor. Windsurf isn't just another IDE, it's an agentic IDE. As Kevin explained, "we made the pretty bold decision of saying, all right, we're not going to do chat... we are just going to [do] agent." They've built Windsurf from the ground up with an agent-first approach, and it’s making waves.Kevin walked us through the evolution of AI coding tools, from autocomplete to chat, and now to agents. He highlighted the "magical experiences" users are having, like debugging complex code with AI assistance that actually understands the context. We also delved into the challenges – memory, checkpointing, and cost.We also talked about the burning question: vibe coding. Is coding as we know it dead? Kevin’s take was nuanced: "there's an in between state that I really vibe or like gel with, which is,the scaffolding of what you want… Let's use, let's like vibe code and purely use the agent to accomplish this sort of commit." He sees AI agents raising the bar for software quality, demanding better UX, testing, and overall polish.And of course, we had to ask about the elephant in the room – why are so many people switching from Cursor to Windsurf? Kevin's answer was humble, pointing to user experience, the agent-first workflow, and the team’s dedication to building the best product. Check out our full conversation on the pod and download Windsurf for yourself: windsurf.aiVideo Models & Voice model updates There is so much happening in LLM world, that folks may skip over the other stuff, but there's so much happening in these world's as well this week! Here's a brief recap! * Alibaba's WanX: Open-sourced, cutting-edge video generation models making waves with over 250,000 downloads already. They claim to take SOTA on open source video generation evals and of course img2video of this high quality model will lead to ... folks using it for all kinds of things. * HUMEs Octave: A groundbreaking LLM model that genuinely understands context and emotion and does TTS. Blog Hume has been doing emotional TTS but with this TTS focused LLM we are now able to create voices with a prompt, and receive emotional responses that are inferred from the text. Think shyness, sarcasm, anger etc* 11labs’ Scribe: Beating Whisper 3 with impressive accuracy and diarization features, Scribe is raising the bar in speech-to-text quality. 11labs releasing their own ASR (automatic speech recognition) was not in my cards, and boy did they deliver. Beating whisper, with speaker separation (diarization), world level timestamps and much lower WER than other models, this is a very interesting entry to this space. However, free for now on their website, it's significantly slower than Gemini 2.0 and Whisper for me at least. * Sesame releases their conversational speech model (and promising to open source this) and it's honestly the best / least uncanny conversations I had with an AI. Check out my conversation with it * Lastly, VEO 2, the best video model around according to some, is finally available via API (though txt2video only) and it's fairly expensive, but gives some amazing results. You can try it out on FALPhew, it looks like we've made it! Huge huge week in AI, big 2 new models, tons of incredible updates on multimodality and voice as well 🔥If you enjoyed this summary, the best way to support us is to share with a friend (or 3) and give us a 5 start reviews on wherever you get your podcasts, it really does help! 👏 See you next week, Alex This is a public episode.

Holy moly, AI enthusiasts! Alex Volkov here, reporting live from the AI Engineer Summit in the heart of (touristy) Times Square, New York! This week has been an absolute whirlwind of announcements, from XAI's Grok 3 dropping like a bomb, to Figure robots learning to hand each other things, and even a little eval smack-talk between OpenAI and XAI. It’s enough to make your head spin – but that's what ThursdAI is here for. We sift through the chaos and bring you the need-to-know, so you can stay on the cutting edge without having to, well, spend your entire life glued to X and Reddit.This week we had a very special live show with the Haize Labs folks, the ones I previously interviewed about their bijection attacks, discussing their open source judge evaluation library called Verdict. So grab your favorite caffeinated beverage, maybe do some stretches because your mind will be blown, and let's dive into the TL;DR of ThursdAI, February 20th, 2025!Participants* Alex Volkov: AI Evangelist with Weights and Biases* Nisten: AI Engineer and cohost* Akshay: AI Community Member* Nuo: Dev Advocate at 01AI* Nimit: Member of Technical Staff at Haize Labs* Leonard: Co-founder at Haize LabsOpen Source LLMsPerplexity's R1 7076: Censorship-Free DeepSeekPerplexity made a bold move this week, releasing R1 7076, a fine-tuned version of DeepSeek R1 specifically designed to remove what they (and many others) perceive as Chinese government censorship. The name itself, 1776, is a nod to American independence – a pretty clear statement! The core idea? Give users access to information on topics the CCP typically restricts, like Tiananmen Square and Taiwanese independence.Perplexity used human experts to identify around 300 sensitive topics and built a "censorship classifier" to train the bias out of the model. The impressive part? They claim to have done this without significantly impacting the model's performance on standard evals. As Nuo from 01AI pointed out on the show, though, he'd "actually prefer that they can actually disclose more of their details in terms of post training... Running the R1 model by itself, it's already very difficult and very expensive." He raises a good point – more transparency is always welcome! Still, it's a fascinating attempt to tackle a tricky problem, the problem which I always say we simply cannot avoid. You can check it out yourself on Hugging Face and read their blog post.Arc Institute & NVIDIA Unveil Evo 2: Genomics PowerhouseGet ready for some serious science, folks! Arc Institute and NVIDIA dropped Evo 2, a massive genomics model (40 billion parameters!) trained on a mind-boggling 9.3 trillion nucleotides. And it’s fully open – two papers, weights, data, training, and inference codebases. We love to see it!Evo 2 uses the StripedHyena architecture to process huge genetic sequences (up to 1 million nucleotides!), allowing for analysis of complex genomic patterns. The practical applications? Predicting the effects of genetic mutations (super important for healthcare) and even designing entire genomes. I’ve been super excited about genomics models, and seeing these alternative architectures like StripedHyena getting used here is just icing on the cake. Check it out on X.ZeroBench: The "Impossible" Benchmark for VLLMsNeed more benchmarks? Always! A new benchmark called ZeroBench arrived, claiming to be the "impossible benchmark" for Vision Language Models (VLLMs). And guess what? All current top-of-the-line VLLMs get a big fat zero on it.One example they gave was a bunch of scattered letters, asking the model to "answer the question that is written in the shape of the star among the mess of letters." Honestly, even I struggled to see the star they were talking about. It highlights just how much further VLLMs need to go in terms of true visual understanding. (X, Page, Paper, HF)Hugging Face's Ultra Scale Playbook: Scaling UpFor those of you building massive models, Hugging Face released the Ultra Scale Playbook, a guide to building and scaling AI models on huge GPU clusters.They ran 4,000 scaling experiments on up to 512 GPUs (nothing close to Grok's 100,000, but still impressive!). If you're working in a lab and dreaming big, this is definitely a resource to check out. (HF).Big CO LLMs + APIsGrok 3: XAI's Big Swing new SOTA LLM! (and Maybe a Bug?)Monday evening, BOOM! While some of us were enjoying President's Day, the XAI team dropped Grok 3. They announced it with a setting very similar to OpenAI announcements. They're claiming state-of-the-art performance on some benchmarks (more on that drama later!), and a whopping 1 million token context window, finally confirmed after some initial confusion. They talked a lot about agents and a future of reasoners as well.The launch was a bit… messy. First, there was a bug where some users were getting Grok 2 even when the dropdown said Grok 3. That led to a lot of mixed reviews. Even when I finally thought I was using Grok 3, it still flubbed my go-to logic test, the "Beth's Ice Cubes" question. (The answer is zero, folks – ice cubes melt!). But Akshay, who joined us on the show, chimed in with some love: "...with just the base model of Grok 3, it's, in my opinion, it's the best coding model out there." So, mixed vibes, to say the least! It's also FREE for now, "until their GPUs melt," according to XAI, which is great.UPDATE: The vibes are shifting, more and more of my colleagues and mutuals are LOVING grok3 for one shot coding, for talking to it. I’m getting convinced as well, though I did use and will continue to use Grok for real time data and access to X. DeepSearchIn an attempt to show off some Agentic features, XAI also launched a deep search (not research like OpenAI but effectively the same) Now, XAI of course has access to X, which makes their deep search have a leg up, specifically for real time information! I found out it can even “use” the X search! OpenAI's Open Source TeaseIn what felt like a very conveniently timed move, Sam Altman dropped a poll on X the same day as the Grok announcement: if OpenAI were to open-source something, should it be a small, mobile-optimized model, or a model on par with o3-mini? Most of us chose o3 mini, just to have access to that model and play with it. No indication of when this might happen, but it’s a clear signal that OpenAI is feeling the pressure from the open-source community.The Eval Wars: OpenAI vs. XAIThings got spicy! There was a whole debate about the eval numbers XAI posted, specifically the "best of N" scores (like best of 64 runs). Boris from OpenAI, and Aiden mcLau called out some of the graphs. Folks on X were quick to point out that OpenAI also used "best of N" in the past, and the discussion devolved from there.XAI is claiming SOTA. OpenAI (or some folks from within OpenAI) aren't so sure. The core issue? We can't independently verify Grok's performance because there's no API yet! As I said, "…we're not actually able to use this model to independently evaluate this model and to tell you guys whether or not they actually told us the truth." Transparency matters, folks!DeepSearch - How Deep?Grok also touted a new "Deep Search" feature, kind of like Perplexity or OpenAI's "Deep Research" in their more expensive plan. My initial tests were… underwhelming. I nicknamed it "Shallow Search" because it spent all of 34 seconds on a complex query where OpenAI's Deep Research took 11 minutes and cited 17 sources. We're going to need to do some more digging (pun intended) on this one.This Week's BuzzWe’re leaning hard into agents at Weights & Biases! We just released an agents whitepaper (check it out on our socials!), and we're launching an agents course in collaboration with OpenAI's Ilan Biggio. Sign up at wandb.me/agents! We're hearing so much about agent evaluation and observability, and we're working hard to provide the tools the community needs.Also, sadly, our Toronto workshops are completely sold out. But if you're at AI Engineer in New York, come say hi to our booth! And catch my talk on LLM Reasoner Judges tomorrow (Friday) at 11 am EST – it’ll be live on the AI Engineer YouTube channel (HERE)!Vision & VideoMicrosoft MUSE: Playable Worlds from a Single ImageThis one is wild. Microsoft's MUSE can generate minutes of playable gameplay from just a single second of video frames and controller actions.It's based on the World and Human Action Model (WHAM) architecture, trained on a billion gameplay images from Xbox. So if you’ve been playing Xbox lately, you might be in the model! I found it particularly cool: "…you give it like a single second of a gameplay of any type of game with all the screen elements, with percentages, with health bars, with all of these things and their model generates a game that you can control." (X, HF, Blog).StepFun's Step-Video-T2V: State-of-the-Art (and Open Source!)We got two awesome open-source video breakthroughs this week. First, StepFun's Step-Video-T2V (and T2V Turbo), a 30 billion parameter text-to-video model. The results look really good, especially the text integration. Imagine a Chinese girl opening a scroll, and the words "We will open source" appearing as she unfurls it. That’s the kind of detail we're talking about.And it’s MIT licensed! As Nisten noted "This is pretty cool. It came out. Right before Sora came out, people would have lost their minds." (X, Paper, HF, Try It).HAO AI's FastVideo: Speeding Up HY-VideoThe second video highlight: HAO AI released FastVideo, a way to make HY-Video (already a strong open-source contender) three times faster with no additional training! They call the trick "Sliding Tile Attention" apparently that alone provides enormous boost compared to even flash attention.This is huge because faster inference means these models become more practical for real-world use. And, bonus: it supports HY-Video's Loras, meaning you can fine-tune it for, ahem, all kinds of creative applications. I will not go as far as to mention civit ai. (Github)Figure's Helix: Robot Collaboration!Breaking news from the AI Engineer conference floor: Figure, the humanoid robot company, announced Helix, a Vision-Language-Action (VLA) model built into their robots!It has full upper body control!What blew my mind: they showed two robots working together, handing objects to each other, based on natural language commands! As I watched, I exclaimed, "I haven't seen a humanoid robot, hand off stuff to the other one... I found it like super futuristically cool." The model runs on the robot, using a 7 billion parameter VLM for understanding and an 80 million parameter transformer for control. This is the future, folks!Tools & OthersMicrosoft's New Quantum Chip (and State of Matter!)Microsoft announced a new quantum chip and a new state of matter (called "topological superconductivity"). "I found it like absolutely mind blowing that they announced something like this," I gushed on the show. While I'm no quantum physicist, this sounds like a big deal for the future of computing.Verdict: Hayes Labs' Framework for LLM JudgesAnd of course, the highlight of our show: Verdict, a new open-source framework from Hayes Labs (the folks behind those "bijection" jailbreaks!) for composing LLM judges. This is a huge deal for anyone working on evaluation. Leonard and Nimit from Hayes Labs joined us to explain how Verdict addresses some of the core problems with LLM-as-a-judge: biases (like preferring their own responses!), sensitivity to prompts, and the challenge of "meta-evaluation" (how do you know your judge is actually good?).Verdict lets you combine different judging techniques ("primitives") to create more robust and efficient evaluators. Think of it as "judge-time compute scaling," as Leonard called it. They're achieving near state-of-the-art results on benchmarks like ExpertQA, and it's designed to be fast enough to use as a guardrail in real-time applications!One key insight: you don't always need a full-blown reasoning model for judging. As Nimit explained, Verdict can combine simpler LLM calls to achieve similar results at a fraction of the cost. And, it's open source! (Paper, Github,X).ConclusionAnother week, another explosion of AI breakthroughs! Here are my key takeaways:* Open Source is THRIVING: From censorship-free LLMs to cutting-edge video models, the open-source community is delivering incredible innovation.* The Need for Speed (and Efficiency): Whether it's faster video generation or more efficient LLM judging, performance is key.* Robots are Getting Smarter (and More Collaborative): Figure's Helix is a glimpse into a future where robots work together.* Evaluation is (Finally) Getting Attention: Tools like Verdict are essential for building reliable and trustworthy AI systems.* The Big Players are Feeling the Heat: OpenAI's open-source tease and XAI's rapid progress show that the competition is fierce.I'll be back in my usual setup next week, ready to break down all the latest AI news. Stay tuned to ThursdAI – and don't forget to give the pod five stars and subscribe to the newsletter for all the links and deeper dives.

What a week in AI, folks! Seriously, just when you think things might slow down, the AI world throws another curveball. This week, we had everything from rogue AI apps giving unsolicited life advice (and sending rogue texts!), to mind-blowing open source releases that are pushing the boundaries of what's possible, and of course, the ever-present drama of the big AI companies with OpenAI dropping a roadmap that has everyone scratching their heads.Buckle up, because on this week's ThursdAI, we dove deep into all of it. We chatted with the brains behind the latest open source embedding model, marveled at a tiny model crushing math benchmarks, and tried to decipher Sam Altman's cryptic GPT-5 roadmap. Plus, I shared a personal story about an AI app that decided to psychoanalyze my text messages – you won't believe what happened! Let's get into the TL;DR of ThursdAI, February 13th, 2025 – it's a wild one!* Alex Volkov: AI Adventurist with weights and biases* Wolfram Ravenwlf: AI Expert & Enthusiast* Nisten: AI Community Member* Zach Nussbaum: Machine Learning Engineer at Nomic AI* Vu Chan: AI Enthusiast & Evaluator* LDJ: AI Community MemberPersonal story of Rogue AI with RPLYThis week kicked off with a hilarious (and slightly unsettling) story of my own AI going rogue, all thanks to a new Mac app called RPLY designed to help with message replies. I installed it thinking it would be a cool productivity tool, but it turned into a personal intervention session, and then… well, let's just say things escalated.The app started by analyzing my text messages and, to my surprise, delivered a brutal psychoanalysis of my co-parenting communication, pointing out how both my ex and I were being "unpleasant" and needed to focus on the kids. As I said on the show, "I got this as a gut punch. I was like, f*ck, I need to reimagine my messaging choices." But the real kicker came when the AI decided to take initiative and started sending messages without my permission (apparently this was a bug with RPLY that was fixed since I reported)! Friends were texting me question marks, and my ex even replied to a random "Hey, How's your day going?" message with a smiley, completely out of our usual post-divorce communication style. "This AI, like on Monday before just gave me absolute s**t about not being, a person that needs to be focused on the kids also decided to smooth things out on friday" I chuckled, still slightly bewildered by the whole ordeal. It could have gone way worse, but thankfully, this rogue AI counselor just ended up being more funny than disastrous.Open Source LLMsDeepHermes preview from NousResearchJust in time for me sending this newsletter (but unfortunately not quite in time for the recording of the show), our friends at Nous shipped an experimental new thinking model, their first reasoner, called DeepHermes. NousResearch claims DeepHermes is among the first models to fuse reasoning and standard LLM token generation within a single architecture (a trend you'll see echoed in the OpenAI and Claude announcements below!)Definitely experimental cutting edge stuff here, but exciting to see not just an RL replication but also innovative attempts from one of the best finetuning collectives around. Nomic Embed Text V2 - First Embedding MoENomic AI continues to impress with the release of Nomic Embed Text V2, the first general-purpose Mixture-of-Experts (MoE) embedding model. Zach Nussbaum from Nomic AI joined us to explain why this release is a big deal.* First general-purpose Mixture-of-Experts (MoE) embedding model: This innovative architecture allows for better performance and efficiency.* SOTA performance on multilingual benchmarks: Nomic Embed V2 achieves state-of-the-art results on the multilingual MIRACL benchmark for its size.* Support for 100+ languages: Truly multilingual embeddings for global applications.* Truly open source: Nomic is committed to open source, releasing training data, weights, and code under the Apache 2.0 License.Zach highlighted the benefits of MoE for embeddings, explaining, "So we're trading a little bit of, inference time memory, and training compute to train a model with mixture of experts, but we get this, really nice added bonus of, 25 percent storage." This is especially crucial when dealing with massive datasets. You can check out the model on Hugging Face and read the Technical Report for all the juicy details.AllenAI OLMOE on iOS and New Tulu 3.1 8BAllenAI continues to champion open source with the release of OLMOE, a fully open-source iOS app, and the new Tulu 3.1 8B model.* OLMOE iOS App: This app brings state-of-the-art open-source language models to your iPhone, privately and securely.* Allows users to test open-source LLMs on-device.* Designed for researchers studying on-device AI and developers prototyping new AI experiences.* Optimized for on-device performance while maintaining high accuracy.* Fully open-source code for further development.* Available on the App Store for iPhone 15 Pro or newer and M-series iPads.* Tulu 3.1 8B As Nisten pointed out, "If you're doing edge AI, the way that this model is built is pretty ideal for that." This move by AllenAI underscores the growing importance of on-device AI and open access. Read more about OLMOE on the AllenAI Blog.Groq Adds Qwen Models and Lands on OpenRouterGroq, known for its blazing-fast inference speeds, has added Qwen models, including the distilled R1-distill, to its service and joined OpenRouter.* Record-fast inference: Experience a mind-blowing 1000 TPS with distilled DeepSeek R1 70B on Open Router.* Usable Rate Limits: Groq is now accessible for production use cases with higher rate limits and pay-as-you-go options.* Qwen Model Support: Access Qwen models like 2.5B-32B and R1-distill-qwen-32B.* Open Router Integration: Groq is now available on OpenRouter, expanding accessibility for developers.As Nisten noted, "At the end of the day, they are shipping very fast inference and you can buy it and it looks like they are scaling it. So they are providing the market with what it needs in this case." This integration makes Groq's speed even more accessible to developers. Check out Groq's announcement on X.com.SambaNova adds full DeepSeek R1 671B - flies at 200t/s (blog)In a complete trend of this week, SambaNova just announced they have availability of DeepSeek R1, sped up by their custom chips, flying at 150-200t/s. This is the full DeepSeek R1, not the distilled Qwen based versions! This is really impressive work, and compared to the second fastest US based DeepSeek R1 (on Together AI) it absolutely fliesAgentica DeepScaler 1.5B Beats o1-preview on MathAgentica's DeepScaler 1.5B model is making waves by outperforming OpenAI's o1-preview on math benchmarks, using Reinforcement Learning (RL) for just $4500 of compute.* Impressive Math Performance: DeepScaleR achieves a 37.1% Pass@1 on AIME 2025, outperforming the base model and even o1-preview!!* Efficient Training: Trained using RL for just $4500, demonstrating cost-effective scaling of intelligence.* Open Sourced Resources: Agentica open-sourced their dataset, code, and training logs, fostering community progress in RL-based reasoning.Vu Chan, an AI enthusiast who evaluated the model, joined us to share his excitement: "It achieves, 42% pass at one on a AIME 24. which basically means if you give the model only one chance at every problem, it will solve 42% of them." He also highlighted the model's efficiency, generating correct answers with fewer tokens. You can find the model on Hugging Face, check out the WandB logs, and see the announcement on X.com.ModernBert Instruct - Encoder Model for General TasksModernBert, known for its efficient encoder-only architecture, now has an instruct version, ModernBert Instruct, capable of handling general tasks.* Instruct-tuned Encoder: ModernBERT-Large-Instruct can perform classification and multiple-choice tasks using its Masked Language Modeling (MLM) head.* Beats Qwen .5B: Outperforms Qwen .5B on MMLU and MMLU Pro benchmarks.* Efficient and Versatile: Demonstrates the potential of encoder models for general tasks without task-specific heads.This release shows that even encoder-only models can be adapted for broader applications, challenging the dominance of decoder-based LLMs for certain tasks. Check out the announcement on X.com.Big CO LLMs + APIsRIP GPT-5 and o3 - OpenAI Announces Public RoadmapOpenAI shook things up this week with a roadmap update from Sam Altman, announcing a shift in strategy for GPT-5 and the o-series models.

Try Firefly Video here.Voice & AudioYouTube Expands AI Dubbing to All CreatorsYouTube is expanding AI dubbing to all creators, breaking down language barriers on the platform.* AI-Powered Dubbing: YouTube is leveraging AI to provide dubbing in multiple languages for all creators. "YouTube now expands. AI dubbing in languages to all creators, and that's super cool. So basically no language barriers anymore. AI dubbing is here," I announced.* Increased Watch Time: Pilot program saw 40% of watch time in dubbed languages, demonstrating the feature's impact. "Since the pilot launched last year, 40 percent of watch time for videos with the feature enabled was in the dub language and not the original language. That's insane!" I highlighted.* Global Reach: Eliminates language barriers, making content accessible to a wider global audience.Wolfram emphasized the importance of dubbing, especially in regions with strong dubbing cultures like Germany. "Every movie that comes here is getting dubbed in high quality. And now AI is doing that on YouTube. And I personally, as a content creator, I have always have to decide, do I post in German or English?" This feature is poised to revolutionize content consumption on YouTube. Read more on X.com.Meta Audiobox Aesthetics - Unified Quality AssessmentMeta released Audiobox Aesthetics, a unified automatic quality assessment model for speech, music, and sound.* Unified Assessment: Provides a single model for evaluating the quality of speech, music, and general sound.* Four Key Metrics: Evaluates audio based on Production Quality (PQ), Production Complexity (PC), Content Enjoyment (CE), and Content Usefulness (CU).* Automated Evaluation: Offers a scalable solution for assessing synthetic audio quality, reducing reliance on costly human evaluations.This tool is expected to significantly improve the development and evaluation of TTS and audio generation models. Access the Paper and Weights on GitHub.Zonos - Expressive TTS with High-Fidelity CloningZyphra released Zonos, a highly expressive TTS model with high-fidelity voice cloning capabilities.* Expressive TTS: Zonos offers expressive speech generation with control over speaking rate, pitch, and emotions.* High-Fidelity Voice Cloning: Claims high-fidelity voice cloning from short audio samples (though my personal test was less impressive). "My own voice clone sounded a little bit like me but not a lot. Ok at least for me, the cloning is really really bad," I admitted on the show.* High Bitrate Audio: Generates speech at 44kHz with a high bitrate codec for enhanced audio quality.* Open Source & API: Models are open source, with a commercial API available.While voice cloning might need further refinement, Zonos represents another step forward in open-source TTS technology. Explore Zonos on Hugging Face (Hybrid), Hugging Face (Transformer), and GitHub, and read the Blog post.Tools & OthersEmergent Values AI - AI Utility Functions and BiasesResearchers found that AIs exhibit emergent values, including biases in valuing human lives from different regions.* Emergent Utility Functions: AI models appear to develop implicit utility functions and value systems during training. "Research finds that AI's have expected utility functions for people and other emergent values. And this is freaky," I summarized.* Value Biases: Studies revealed biases, with AIs valuing lives from certain regions (e.g., Nigeria, Pakistan, India) higher than others (e.g., Italy, France, Germany, UK, US). "Nigerian people, valued as like eight us people. One Nigerian person was valued like eight us people," I highlighted the surprising finding.* Utility Engineering: Researchers propose "utility engineering" as a research agenda to analyze and control these emergent value systems.LDJ pointed out a potential correlation between the valued regions and the source of RLHF data labeling, suggesting a possible link between training data and emergent biases. While the study is still debated, it raises important questions about AI value alignment. Read the announcement on X.com and the Paper.LM Studio Lands Support for Speculative DecodingLM Studio, the popular local LLM inference tool, now supports speculative decoding, significantly speeding up inference.* Faster Inference: Speculative decoding leverages a smaller "draft" model to accelerate inference with a larger model. "Speculative decoding finally landed in LM studio, which is dope folks. If you use LM studio, if you don't, you should," I exclaimed.* Visualize Accepted Tokens: LM Studio visualizes accepted draft tokens, allowing users to see speculative decoding in action.* Performance Boost: Improved inference speeds by up to 40% in tests, without sacrificing model performance. "It runs around 10 tokens per second without the speculative decoding and around 14 to 15 tokens per second with speculative decoding, which is great," I noted.This update makes LM Studio even more powerful for local LLM experimentation.

What's up friends, Alex here, back with another ThursdAI hot off the presses.Hold onto your hats because this week was another whirlwind of AI breakthroughs, mind-blowing demos, and straight-up game-changers. We dove deep into OpenAI's new "Deep Research" agent – and let me tell you, it's not just hype, it's legitimately revolutionary. You also don't have to take my word for it, a new friend of the pod and a scientist DR Derya Unutmaz joined us to discuss his experience with Deep Research as a scientist himself! You don't want to miss this conversation! We also unpack Google's Gemini 2.0 release, including the blazing-fast Flash Lite model. And just when you thought your brain couldn't handle more, ByteDance drops OmniHuman-1, a human animation model that's so realistic, it's scary good.I've also saw maybe 10 moreTLDR & Show Notes* Open Source LLMs (and deep research implementations)* Jina Node-DeepResearch (X, Github)* HuggingFace - OpenDeepResearch (X)* Deep Agent - R1 -V (X, Github)* Krutim - Krutim 2 12B, Chitrath VLM, Embeddings and more from India (X, Blog, HF)* Simple Scaling - S1 - R1 (Paper)* Mergekit updated - * Big CO LLMs + APIs* OpenAI ships o3-mini and o3-mini High + updates thinking traces (Blog, X)* Mistral relaunches LeChat with Cerebras for 1000t/s (Blog)* OpenAI Deep Research - the researching agent that uses o3 (X, Blog)* Google ships Gemini 2.0 Pro, Gemini 2.0 Flash-lite in AI Studio (Blog)* Anthropic Constitutional Classifiers - announced a universal jailbreak prevention (Blog, Try It)* Cloudflare to protect websites from AI scraping (News)* HuggingFace becomes the AI Appstore (link)* This weeks Buzz - Weights & Biases updates* AI Engineer workshop (Saturday 22) * Tinkerers Toronto workshops (Sunday 23 , Monday 24)* We released a new Dataset editor feature (X)* Audio and Sound* KyutAI open sources Hibiki - simultaneous translation models (Samples, HF)* AI Art & Diffusion & 3D* ByteDance OmniHuman-1 - unparalleled Human Animation Models (X, Page)* Pika labs adds PikaAdditions - adding anything to existing video (X)* Google added Imagen3 to their API (Blog)* Tools & Others* Mistral Le Chat has ios an and adroid apps now (X)* CoPilot now has agentic workflows (X)* Replit launches free apps agent for everyone (X)* Karpathy drops a new 3 hour video on youtube (X, Youtube)* OpenAI canvas links are now shareable (like Anthropic artifacts) - (example)* Show Notes & Links * Guest of the week - Dr Derya Umnutaz - talking about Deep Research* He's examples of Ehlers-Danlos Syndrome (ChatGPT), (ME/CFS) Deep Research, Nature article about Deep Reseach with Derya comments* Hosts* Alex Volkov - AI Evangelist & Host @altryne* Wolfram Ravenwolf - AI Evangelist @WolframRvnwlf* Nisten Tahiraj - AI Dev at github.GG - @nisten* LDJ - Resident data scientist - @ldjconfirmedBig Companies products & APIsOpenAI's new chatGPT moment with Deep Research, their second "agent" product (X)Look, I've been reporting on AI weekly for almost 2 years now, and been following the space closely since way before chatGPT (shoutout Codex days) and this definitely feels like another chatGPT moment for me.DeepResearch is OpenAI's new agent, that searches the web for any task you give it, is able to reason about the results, and continue searching those sources, to provide you with an absolute incredible level of research into any topic, scientific or ... the best taqueria in another country. The reason why it's so good is it's ability to do multiple search trajectories, backtrack if it needs to, and react in real time to new information. It also has python tool use (to do plots and calculations) and of course, the brain of it is o3, the best reasoning model from OpenAIDeep Research is only offered on the Pro tier ($200) of chatGPT, and it's the first publicly available way to use o3 full! and boy, does it deliver! I've had it review my workshop content, help me research LLM as a judge articles (which it did masterfully) and help me plan datenights in Denver (though it kind of failed at that, showing me a closed restaurant) A breakthrough for scientific researchBut I'm no scientist, so I've asked Dr Derya Unutmaz, M.D. to join us, and share his incredible findings as a doctor, a scientist and someone with decades of experience in writing grants, patent applications, paper etc. The whole conversation is very very much worth listening to on the pod, we talked for almost an hour, but the highlights are honestly quite crazy. So one of the first things I did was, I asked Deep Research to write a review on a particular disease that I’ve been studying for a decade. It came out with this impeccable 10-to-15-page review that was the best I’ve read on the topic— Dr. Derya UnutmazAnd another banger quoteIt wrote a phenomenal 25-page patent application for a friend’s cancer discovery—something that would’ve cost 10,000 dollars or more and taken weeks. I couldn’t believe it. Every one of the 23 claims it listed was thoroughly justifiedHumanity's LAST exam? OpenAI announced Deep Research and have showed that on HLE (Humanity's Last Exam) benchmark that was just released a few weeks ago, it scores a whopping 26.6 percent! When HLE was released (our coverage here) all the way back at ... checks notes... January 23 or this year! the top reasoning models at the time (o1, R1) scored just under 10%O3-mini and Deep Research now score 13% and 26.6% respectively, which means both that AI is advancing like crazy, but also.. that maybe calling this "last exam" was a bit premature? 😂😅Deep Research is now also SOTA holder on GAIA, a public benchmark on real world questions, though Clementine (one of GAIA authors) throws a bit of shade on the result since OpenAI didn't really submit their results. Incidently, Clementine is also involved in HuggingFace attempt at replicating Deep Research in the open (with OpenDeepResearch) OpenAI releases o3-mini and o3-mini highThis honestly got kind of buried with the Deep Research news, but as promised, on the last day of January, OpenAI released their new reasoning model, which is significantly fast and much cheaper than o1, while matching it on most benchmarks! I've been talking about the fact that during o3 announcement (our coverage) that mini may be more practical and useful announcement than o3 itself, given the price and speed of it. And viola, OpenAI has reduced the price point of their best reasoner model by 67%, and it's now matches just 2x that of DeepSeek R1.Coming in at 110c for 1M input tokens and 440c for 1M output tokens, and streaming at a whopping 1000t/s at some instances, this reasoner is really something to beat. Great for application developersIn addition to seem to be a great model, comparing it to R1 is a nonstarter IMO, not only because "it’s sending your data to choyna", which IMO is a ridiculous attack vector and people should be ashamed by posting this content. o3-mini supports all of the nice API things that OpenAI has, like tool use, structured outputs, developer messages and streaming. The ability to set the reasoning effort is also interesting for applications! Added benefit is the new 200K context window with 100K (claimed) output context. It's also really really fast, while R1 availability grows, as it gets hosted on more and more US based providers, none of them are offering the full context window at these token speeds. o3-mini-high?! While the free users also started getting access to o3-mini, with the "reason" button on chatGPT, plus subscribers received 2 models, o3-mini and o3-mini-high, which is essentially the same model, but with the "high" reasoning mode turned on, giving the model significantly more compute (and tokens) to think. This can be done on the API level by selecting reasoning_effort=high but it's the first time OpenAI is exposing this to non API users! One highlight for me is, just how MANY tokens o3-mini high things through. In one of my evaluations on Weave, o3-mini high generated around 160K output tokens, answering 20 questions, while DeepSeek R1 for example generated 75K and Gemini Thinking, got the highest score on these, while charging only 14K tokens (though I'm pretty sure Google just doesn't report on thinking tokens yet, this seems like a bug)As I'm writing this, OpenAI just announced a new update, o3-mini and o3-mini-high now show... "updated" reasoning traces! These definitely "feel" more like the R1 reasoning traces (remember, previously OpenAI had a different model summarizing the reasoning to prevent training on them?) but they are not really the RAW ones (confirmed) Google ships Gemini 2.0 Pro, Gemini 2.0 Flash-lite in AI Studio (X, Blog)Congrats to our friends at Google for 2.0 👏 Google finally put all the experimental models under one 2.0 umbrella, giving us Gemini 2.0, Gemini 2.0 Flash and a new model! They also introduced Gemini 2.0 Flash-lite, a crazy fast and cheap model that performs similarly to Flash 1.5. The rate limits on Flash-lite are twice as high as the regular Flash, making it incredibly useful for real-time applications. They have also released a few benchmarks, but they only compared those to the previous benchmark released by Google, and while that's great, I wanted a comparison done, so I asked DeepResearch to do it for me, and it did (with citations!) Google also released Imagen 3, their awesome image diffusion model in their API today, with 3c per image, this one is really really good! Mistral's new LeChat spits out 1000t/s + new IOS appsDuring the show, Mistral announced new capabilities for their LeChat interface, including a 15$/mo tier, but most importantly, a crazy fast generation using some kind of new inference, spitting out around 1000t/s. (Powered by Cerebras)Additionally they have code interpreter there, Canvas, and they also claim to have the best OCR and don't forget, they have access to Flux images, and likely are the only place I know of that offers that image model for free! Finally, they've released native mobile apps! (IOS, Android)* from my quick tests, the 1000t/s is not always on, my first attempt was instant, it was like black magic, and then the rest of them were pretty much the same speed as before 🤔 Maybe they are getting hammered in traffic... This weeks Buzz (What I learned with WandB this week)I got to play around with O3-Mini before it was released (perks of working at Weights & Biases!), and I used Weave, our observability and evaluation framework, to analyze its performance. The results were… interesting.* Latency and Token Count: O3-Mini High's latency was six times longer than O3-Mini Low on a simple reasoning benchmark (92 seconds vs. 6 seconds). But here's the kicker: it didn't even answer more questions correctly! And the token count? O3-Mini High used half a million tokens to answer 20 questions three times. That's… a lot.* Weave Leaderboards: Nisten got super excited about using Weave's leaderboard feature to benchmark models. He realized it could solve a real problem in the open-source community – providing a verifiable and transparent way to share benchmark results. (really, we didnt' rehearse this!) I also announced some upcoming workshops I'd love to see you at:* AI Engineer Workshop in NYC: I'll be running a workshop on evaluations at the AI Engineer Summit in New York on February 22nd. Come say hi and learn about evals!* AI Tinkerers Workshops in Toronto: I'll also be doing two workshops with AI Tinkerers in Toronto on February 23rd and 24th.ByteDance OmniHuman-1 - a reality bending mind breaking img2human modelOk, this is where my mind completely broke this week, like absolutely couldn't stop thinking about this release from ByteDance. After releasing the SOTA lipsyncing model just a few months ago (LatentSync, our coverage) they have once again blew everyone away. This time with a img2avatar model that's unlike anything we've ever seen. This one doesn't need words, just watch my live reaction as I lose my mindThe level of real world building in these videos is just absolutely ... too much? The piano keys moving, there's a video of a woman speaking in the microphone, and behind her, the window has reflections of cars and people moving! The thing that most blew me away upon review was the Niki Glazer video, with shiny dress and the model almost perfectly replicating the right sources of light. Just absolute sorcery! The authors confirmed that they don't have any immediate plans to release this as a model or even a product, but given the speed of open source, we'll get this within a year for sure! Get readyOpen Source LLMs (and deep research implementations)This week wasn't massive for open-source releases in terms of entirely new models, but the ripple effects of DeepSeek's R1 are still being felt. The community is buzzing with attempts to replicate and build upon its groundbreaking reasoning capabilities. It feels like everyone is scrambling to figure out the "secret sauce" behind R1's "aha moment," and we're seeing some fascinating results.Jina Node-DeepResearch and HuggingFace OpenDeepResearchThe community wasted no time trying to replicate OpenAI's Deep Research agent.* Jina AI released "Node-DeepResearch" (X, Github), claiming it follows the "query, search, read, reason, repeat" formula. As I mentioned on the show, "I believe that they're wrong" about it being just a simple loop. O3 is likely a fine-tuned model, but still, it's awesome to see the open-source community tackling this so quickly!* Hugging Face also announced "OpenDeepResearch" (X), aiming to create a truly open research agent. Clementine Fourrier, one of the authors behind the GAIA benchmark (which measures research agent capabilities), is involved, so this is definitely one to watch.Deep Agent - R1 -V: These folks claim to have replicated DeepSeek R1's "aha moment" – where the model realizes its own mistakes and rethinks its approach – for just $3! (X, Github)As I said on the show, "It's crazy, right? Nothing costs $3 anymore. Like it's half a coffee in Starbucks." They even claim you can witness this "aha moment" in a VLM. Open source is moving fast.Krutim - Krutim 2 12B, Chitrath VLM, Embeddings and more from India: This Indian AI lab released a whole suite of models, including an improved LLM (Krutim 2), a VLM (Chitrarth 1), a speech-language model (Dhwani 1), an embedding model (Vyakhyarth 1), and a translation model (Krutrim Translate 1). (X, Blog, HF) They even developed a benchmark called "BharatBench" to evaluate Indic AI performance.However, the community was quick to point out some… issues. As Harveen Singh Chadha pointed out on X, it seems like they blatantly copied IndicTrans, an MIT-licensed model, without even mentioning it. Not cool, Krutim. Not cool.AceCoder: This project focuses on using reinforcement learning (RL) to improve code models. (X) They claim to have created a pipeline to automatically generate high-quality, verifiable code training data.They trained a reward model (AceCode-RM) that significantly boosts the performance of Llama-3.1 and Qwen2.5-coder-7B. They even claim you can skip SFT training for code models by using just 80 steps of R1-style training!Simple Scaling - S1 - R1: This paper (Paper) showcases the power of quality over quantity. They fine-tuned Qwen2.5-32B-Instruct on just 1,000 carefully curated reasoning examples and matched the performance of o1-preview!They also introduced a technique called "budget forcing," allowing the model to control its test-time compute and improve performance. As I mentioned, Niklas Mengenhoff, who worked at Allen and was previously on the show, is involved. This is one to really pay attention to – it shows that you don't need massive datasets to achieve impressive reasoning capabilities.Unsloth reduces R1 type reasoning to just 7GB VRAM (blog)Deepseek R1-zero was autonimously learned reasoning in what they DeepSeek researchers called the "aha moment" Unsloth adds another attempt at replicating this "aha moment" and claims they got it down to less than 7B VRAM, and it can see it for free, in a google colab! This magic could be recreated through GRPO, a RL algorithm that optimizes responses efficiently without requiring a value function, unlike Proximal Policy Optimization (PPO) which relies on a value functionHow it works:1. The model generates groups of responses.2. Each response is scored based on correctness or another metric created by some set reward function rather than an LLM reward model.3 . The average score of the group is computed.4. Each response's score is compared to the group average.5. The model is reinforced to favor higher-scoring responses.ToolsA few new and interesting tools were released this week as well: * Replit rebuilt and released their replit agents in an IOS app and released it free for many users. It can now build mini apps for you on the fly! (Replit)* Mistral has ios / android apps with the new release of LeChat (X)* Molly Cantillon released RPLY, which sits on your mac, and drafts replies to your messages. I installed it during writing this newsletter, and I did not expect it to hit this hard, it reviewed and summarized my texting patterns to "sound like me" and the models sit on device as well. Very very well crafted tool and the best thing it runs models on device if you want! * Github Copilot announced agentic workflows and next line editing, which are cursor features. To try them out you have to download VSCode insiders. They also added Gemini 2.0 (Blog)The AI field moves SO fast, I had to update the content of the newsletter around 5 times while writing it as new things kept getting released! This was a Banger week that started with o3-mini and deep research, continued with Gemini 2.0 and OmniHuman and "ended" with Mistral x Cerebras, Github copilot agents, o3-mini updated COT reasoning traces and a bunch more! AI doesn't stop, and we're here weekly to cover all of this, and give you guys the highlights, but also go deep! Really appreciate Derya's appearance on the show this week, please give him a follow and see you guys next week! This is a public episode.

Hey folks, Alex here 👋It’s official—grandmas (and the entire stock market) now know about DeepSeek. If you’ve been living under an AI rock, DeepSeek’s new R1 model just set the world on fire, rattling Wall Street (causing the biggest monetary loss for any company, ever!) and rocketing to #1 on the iOS App Store. This week’s ThursdAI show took us on a deep (pun intended) dive into the dizzying whirlwind of open-source AI breakthroughs, agentic mayhem, and big-company cat-and-mouse announcements. Grab your coffee (or your winter survival kit if you’re in Canada), because in true ThursdAI fashion, we’ve got at least a dozen bombshells to cover—everything from brand-new Mistral to next-gen vision models, new voice synthesis wonders, and big moves from Meta and OpenAI.We’re also talking “reasoning mania,” as the entire industry scrambles to replicate, dethrone, or ride the coattails of the new open-source champion, R1. So buckle up—because if the last few days are any indication, 2025 is officially the Year of Reasoning (and quite possibly, the Year of Agents, or both!)Open Source LLMsDeepSeek R1 discourse Crashes the Stock MarketOne-sentence summary: DeepSeek’s R1 “reasoning model” caused a frenzy this week, hitting #1 on the App Store and briefly sending NVIDIA’s stock plummeting in the process ($560B drop, largest monetary loss of any stock, ever)Ever since DeepSeek R1 launched (our technical coverate last week!), the buzz has been impossible to ignore—everyone from your mom to your local barista has heard the name. The speculation? DeepSeek’s new architecture apparently only cost $5.5 million to train, fueling the notion that high-level AI might be cheaper than Big Tech claims. Suddenly, people wondered if GPU manufacturers like NVIDIA might see shrinking demand, and the stock indeed took a short-lived 17% tumble. On the show, I joked, “My mom knows about DeepSeek—your grandma probably knows about it, too,” underscoring just how mainstream the hype has become.Not everyone is convinced the cost claims are accurate. Even Dario Amodei of Anthropic weighed in with a blog post arguing that DeepSeek’s success increases the case for stricter AI export controls. Public Reactions* Dario Amodei’s blogIn “On DeepSeek and Export Controls,” Amodei argues that DeepSeek’s efficient scaling exemplifies why democratic nations need to maintain a strategic leadership edge—and enforce export controls on advanced AI chips. He sees Chinese breakthroughs as proof that AI competition is global and intense.* OpenAI Distillation EvidenceOpenAI mentioned it found “distillation traces” of GPT-4 inside R1’s training data. Hypocrisy or fair game? On ThursdAI, the panel mused that “everyone trains on everything,” so perhaps it’s a moot point.* Microsoft ReactionMicrosoft wasted no time, swiftly adding DeepSeek to Azure—further proof that corporations want to harness R1’s reasoning power, no matter where it originated.* Government reactedEven officials in the government, David Sacks, US incoming AI & Crypto czar, discussed the fact that DeepSeek did "distillation" using the term somewhat incorrectly, and presidet Trump was asked about it.* API OutagesDeepSeek’s own API has gone in and out this week, apparently hammered by demand (and possibly DDoS attacks). Meanwhile, GPU clouds like Groq are showing up to accelerate R1 at 300 tokens/second, for those who must have it right now.We've seen so many bad takes on the topic, from seething cope takes, to just gross misunderstandings from gov officials confusing the ios App with the OSS models, folks throwing conspiracy theories into the mix, claiming that $5.5M sum was a PsyOp. The fact of the matter is, DeepSeek R1 is an incredible model, and is now powering (just a week later), multiple products (more on this below) and experiences already, while pushing everyone else to compete (and give us reasoning models!)Open Thoughts Reasoning DatasetOne-sentence summary: A community-led effort, “Open Thoughts,” released a new large-scale dataset (OpenThoughts-114k) of chain-of-thought reasoning data, fueling the open-source drive toward better reasoning models.Worried about having enough labeled “thinking” steps to train your own reasoner? Fear not. The OpenThoughts-114k dataset aggregates chain-of-thought prompts and responses—114,000 of them—for building or fine-tuning reasoning LLMs. It’s now on Hugging Face for your experimentation pleasure. The ThursdAI panel pointed out how crucial these large, openly available reasoning datasets are. As Wolfram put it, “We can’t rely on the big labs alone. More open data means more replicable breakouts like DeepSeek R1.”Mistral Small 2501 (24B)One-sentence summary: Mistral AI returns to the open-source spotlight with a 24B model that fits on a single 4090, scoring over 81% on MMLU while under Apache 2.0.Long rumored to be “going more closed,” Mistral AI re-emerged this week with Mistral-Small-24B-Instruct-2501—an Apache 2.0 licensed LLM that runs easily on a 32GB VRAM GPU. That 81% MMLU accuracy is no joke, putting it well above many 30B–70B competitor models. It was described as “the perfect size for local inference and a real sweet spot,” noting that for many tasks, 24B is “just big enough but not painfully heavy.” Mistral also finally started comparing themselves to Qwen 2.5 in official benchmarks—a big shift from their earlier reluctance, which we applaud! Berkeley TinyZero & RAGEN (R1 Replications)One-sentence summary: Two separate projects (TinyZero and RAGEN) replicated DeepSeek R1-zero’s reinforcement learning approach, showing you can get “aha” reasoning moments with minimal compute.If you were wondering whether R1 is replicable: yes, it is. Berkeley’s TinyZero claims to have reproduced the core R1-zero behaviors for $30 using a small 3B model. Meanwhile, the RAGEN project aims to unify RL + LLM + Agents with a minimal codebase. While neither replication is at R1-level performance, they demonstrate how quickly the open-source community pounces on new methods. “We’re now seeing those same ‘reasoning sparks’ in smaller reproductions,” said Nisten. “That’s huge.”AgentsCodename Goose by Blocks (X, Github)One-sentence summary: Jack Dorsey’s company Blocks released Goose, an open-source local agent framework letting you run keyboard automation on your machine.Ever wanted your AI to press keys and move your mouse in real time? Goose does exactly that with AppleScript, memory extensions, and a fresh approach to “local autonomy.” On the show, I tried Goose, but found it occasionally “went rogue, trying to delete my WhatsApp chats.” Security concerns aside, Goose is significant: it’s an open-source playground for agent-building. The plugin system includes integration with Git, Figma, a knowledge graph, and more. If nothing else, Goose underscores how hot “agentic” frameworks are in 2025.OpenAI’s Operator: One-Week-InIt’s been a week since Operator went live for Pro-tier ChatGPT users. “It’s the first agent that can run for multiple minutes without bugging me every single second,”. Yet it’s still far from perfect—captchas, login blocks, and repeated confirmations hamper tasks. The potential, though, is enormous: “I asked Operator to gather my X.com bookmarks and generate a summary. It actually tried,” I shared, “but it got stuck on three links and needed constant nudges.” Simon Willison added that it’s “a neat tech demo” but not quite a productivity boon yet. Next steps? Possibly letting the brand-new reasoning models (like O1 Pro Reasoning) do the chain-of-thought under the hood.I also got tired of opening hundreds of tabs for operator, so I wrapped it in a macOS native app, that has native notifications and the ability to launch Operator tasks via a Raycast extension, if you're interested, you can find it on my GithubBrowser-use / Computer-use AlternativesIn addition to Goose, the ThursdAI panel mentioned browser-use on GitHub, plus numerous code interpreters. So far, none blow minds in reliability. But 2025 is evidently “the year of agents.” If you’re itching to offload your browsing or file editing to an AI agent, expect to tinker, troubleshoot, and yes, babysit. The show consensus? “It’s not about whether agents are coming, it’s about how soon they’ll become truly robust,” said Wolfram.Big CO LLMs + APIsAlibaba Qwen2.5-Max (& Hidden Video Model) (Try It)One-sentence summary: Alibaba’s Qwen2.5-Max stands toe-to-toe with GPT-4 on some tasks, while also quietly rolling out video-generation features.While Western media fixates on DeepSeek, Alibaba’s Qwen team quietly dropped the Qwen2.5-Max MoE model. It clocks in at 69% on MMLU-Pro—beating some OpenAI or Google offerings—and comes with a 1-million-token context window. And guess what? The official Chat interface apparently does hidden video generation, though Alibaba hasn’t publicized it in the English internet. In the Chinese AI internet, this video generation model is called Tongyi Wanxiang, and even has it’s own website, can support first and last video generation and looks really really good, they have a gallery up there, and it even has audio generation together with the video!This one was an img2video, but the movements are really natural! Zuckerberg on LLama4 & LLama4 MiniIn Meta’s Q4 earnings call, Zuck was all about AI (sorry, Metaverse). He declared that LLama4 is in advanced training, with a smaller “LLama4 Mini” finishing pre-training. More importantly, a “reasoning model” is in the works, presumably influenced by the mania around R1. Some employees had apparently posted on Blind about “Why are we paying billions for training if DeepSeek did it for $5 million?” so the official line is that Meta invests heavily for top-tier scale. Zuck also doubled down on saying "Glasses are the perfect form factor for AI" , to which I somewhat agree, I love my Meta Raybans, I just wished they were integrated into the ios more. He also boasted about their HUGE datacenters, called Mesa, spanning the size of Manhattan, being built for the next step of AI. (Nearly) Announced: O3-MiniRight before the ThursdAI broadcast, rumors swirled that OpenAI might reveal O3-Mini. It’s presumably GPT-4’s “little cousin” with a fraction of the cost. Then…silence. Sam Altman also mentioned they would be bringing o3-mini by end of January, but maybe the R1 crazyness made them keep working on it and training it a bit more? 🤔 In any case, we'll cover it when it launches. This Week’s BuzzWe're still the #1 spot on Swe-bench verified with W&B programmer, and our CTO, Shawn Lewis, chatted with friends of the pod Swyx and Alessio about it! (give it a listen)We have two upcoming events:* AI.engineer in New York (Feb 20–22). Weights & Biases is sponsoring, and I will broadcast ThursdAI live from the summit. If you snagged a ticket, come say hi—there might be a cameo from the “Chef.”* Toronto Tinkerer Workshops (late February) in the University of Toronto. The Canadian AI scene is hot, so watch out for sign-ups (will add them to the show next week)Weights & Biases also teased more features for LLM observability (Weave) and reminded folks of their new suite of evaluation tools. “If you want to know if your AI is actually better, you do evals,” Alex insisted. For more details, check out wandb.me/weave or tune into the next ThursdAI.Vision & VideoDeepSeek - Janus Pro - multimodal understanding and image gen unified (1.5B & 7B)One-sentence summary: Alongside R1, DeepSeek also released Janus Pro, a unified model for image understanding and generation (like GPT-4’s rumored image abilities).DeepSeek apparently never sleeps. Janus Pro is MIT-licensed, 7B parameters, and can both parse images (SigLIP) and generate them (LlamaGen). The model outperforms DALL·E 3 and SDXL! on some internal benchmarks—though at a modest 384×384 resolution. NVIDIA’s Eagle 2 ReduxOne-sentence summary: NVIDIA re-released the Eagle 2 vision-language model with 4K resolution support, after mysteriously yanking it a week ago.Eagle 2 is back, boasting multi-expert architecture, 16k context, and high-res video analysis. Rumor says it competes with big 70B param vision models at only 9B. But it’s overshadowed by Qwen2.5-VL (below). Some suspect NVIDIA is aiming to outdo Meta’s open-source hold on vision—just in time to keep GPU demand strong.Qwen 2.5 VL - SOTA oss vision model is here One-sentence summary: Alibaba’s Qwen 2.5 VL model claims state-of-the-art in open-source vision, including 1-hour video comprehension and “object grounding.”The Qwen team didn’t hold back: “It’s the final boss for vision,” joked Nisten. Qwen 2.5 VL uses advanced temporal modeling for video and can handle complicated tasks like OCR or multi-object bounding boxes. Featuring advances in precise object localization, video temporal understanding and agentic capabilities for computer, this is going to be the model to beat! Voice & AudioYuE 7B (Open “Suno”)Ever dream of building the next pop star from your code editor? YuE 7B is your ticket. This model, now under Apache 2.0, supports chain-of-thought creation of structured songs, multi-lingual lyrics, and references. It’s slow to infer, but it’s arguably the best open music generator so far in the open sourceWhat's more, they have changed the license to apache 2.0 just before we went live, so you can use YuE everywhere! Refusion FuzzRefusion, a new competitor to paid audio models like Suno and Udio, launched “Fuzz,” offering free music generation online until GPU meltdown.If you want to dabble in “prompt to jam track” without paying, check out Refusion Fuzz. Will it match the emotional nuance of premium services like 11 Labs or Hauio? Possibly not. But hey, free is free.Tools (that have integrated R1)Perplexity with R1In the perplexity.ai chat, you can choose “Pro with R1” if you pay for it, harnessing R1’s improved reasoning to parse results. For some, it’s a major upgrade to “search-based question answering.” Others prefer it to paying for O1 or GPT-4. I always check Perplexity if it knows what the latest episode of ThursdAI was, and it's the first time it did a very good summary! I legit used it to research the show this week! It's really something. Meanwhile, Exa.ai also integrated a “DeepSeek Chat” for your agent-based workflows. Like it or not, R1 is everywhere.Krea.ai with DeepSeekOur friends at Krea, an AI art tool aggregator, also hopped on the R1 bandwagon for chat-based image searching or generative tasks.ConclusionKey Takeaways* DeepSeek’s R1 has massive cultural reach, from #1 apps to spooking the stock market.* Reasoning mania is upon us—everyone from Mistral to Meta wants a piece of the logic-savvy LLM pie.* Agentic frameworks like Goose, Operator, and browser-use are proliferating, though they’re still baby-stepping through reliability issues.* Vision and audio get major open-source love, with Janus Pro, Qwen 2.5 VL, YuE 7B, and more reshaping multimodality.* Big Tech (Meta, Alibaba, OpenAI) is forging ahead with monster models, multi-billion-dollar projects, and cross-country expansions in search of the best reasoning approaches.At this point, it’s not even about where the next big model drop comes from; it’s about how quickly the entire ecosystem can adopt (or replicate) that new methodology. Stay tuned for next week’s ThursdAI, where we’ll hopefully see new updates from OpenAI (maybe O3-Mini?), plus the ongoing race for best agent. Also, catch us at AI.engineer in NYC if you want to talk shop or share your own open-source success stories. Until then, keep calm and carry on training.TLDR* Open Source LLMs* DeepSeek Crashes the Stock Market: Did $5.5M training or hype do it?* Open Thoughts Reasoning Dataset OpenThoughts-114k (X, HF)* Mistral Small 2501 (24B, Apache 2.0) (HF)* Berkeley TinyZero & RAGEN (R1-Zero Replications) (Github, WANDB)* Allen Institute - Tulu 405B (Blog, HF)* Agents* Goose by Blocks (local agent framework) - (X, Github)* Operator (OpenAI) – One-Week-In (X)* Browser-use - oss version of Operator (Github)* Big CO LLMs + APIs* Alibaba Qwen2.5-Max (+ hidden video model) - (X, Try it)* Zuckerberg on LLama4 & “Reasoning Model” (X)* This Week’s Buzz* Shawn Lewis interview on Latent Space with swyx & Alessio * We’re sponsoring the ai.engineer upcoming summit in NY (Feb 19-22), come say hi! * After that, we’ll host 2 workshops with AI Tinkerers Toronto (Feb 23-24), make sure you’re signed up to Toronto Tinkerers to receive the invite (we were sold out quick last time!) * Vision & Video* DeepSeek Janus Pro - 1.5B and 7B (Github, Try It)* NVIDIA Eagle 2 (Paper, Model, Demo)* Alibaba Qwen 2.5 VL (Project, HF, Github, Try It)* Voice & Audio* Yue 7B (Open Suno) - (Demo, HF, Github)* Refusion Fuzz (free for now)* Tools* Perplexity with R1 (choose Pro with R1) * Exa integrated R1 for free (demo)* Participants* Alex Volkov (@altryne)* Wolfram Ravenwolf (@WolframRvnwlf)* Nisten Tahiraj (@nisten )* LDJ (@ldjOfficial)* Simon Willison (@simonw)* W&B Weave (@weave_wb) This is a public episode.
