It's Wednesday, November 4, and this is the Valley Morning Briefing. Today: OpenAI says GPT-6 Astra designed a hardware device in under a week. Google says students can't get Google Search without its AI features. Claude Code's head of product, Cat Wu, has left Anthropic. Critics say an MIT claim about GPT-6 Astra editing weights is misleading. Let's go.OpenAI says two of its employees used GPT-6 Astra in a side project to design a small hardware device in under a week.
The device is a desk gadget for talking to Codex. It has a push-to-talk button and a small screen. Justin Lin, the OpenAI researcher who built it, calls it a "Codex pet". He built it so he could keep track of his coding agents while his laptop stays closed.
OpenAI credits Astra with the design work. It says the model chose the look of the device and designed the case and the frame that holds the parts. Astra also picked the electronic components, laid out the circuit board to fit the case, and wrote the firmware and the interface that connect the device to Codex.
OpenAI describes the goal as a device made without any direct human edits. Getting the design ready for manufacturing took several rounds of review, because Astra did not consistently account for the factory's limits, tolerances and assembly details. OpenAI does not say who made those fixes, or whether the device stayed free of human edits. It then took a contract manufacturer less than a month to produce the first few units. In a video, Lin said: "Obviously, took a few rounds with the factory, but this is what came back."
An outside test in September looked at one step of this work. The circuit-board maker NextPCB gave Astra a board with the parts already placed and asked it to connect them. Astra finished in about 12 minutes by handing the job to Freerouting, an open-source tool. When it had to work by itself inside the design software KiCad, it drew three short traces in an hour before the test was stopped.
OpenAI also gave a benchmark score for a model it has not released. The test, which OpenAI calls BenchCAD 2.0, checks whether models can rebuild 3D parts and find connections on circuit boards. A newer internal model scored 0.875. GPT-6 Astra scored 0.594 at its highest reasoning setting. OpenAI gives no name or release date for the internal model, and no scores for other companies' models. The academics who created the original BenchCAD write that their test does not capture manufacturing tolerances or assembly.
Inside OpenAI, the hardware teams' use of Codex and ChatGPT, measured in tokens, has grown 23-fold since February. The company is also testing its models with the motorsports team Chip Ganassi Racing and with Mazda's aerodynamics engineers. OpenAI says it will share results from the Mazda work in the coming months.Google said on Tuesday that it will switch off its AI products and Google Search for student accounts from kindergarten through 12th grade, until each school turns them on. But a school that wants Google Search also has to accept the AI built into it.
Besides Google Search, the change applies to three Gemini products: the Gemini chatbot, Gemini Notebook and Gemini in Classroom. Until now, Gemini was on by default for schools that use Google Classroom. Forbes reports that the new setup will start in early 2027.
Google's blog post presented the change as more control for schools, and did not mention any link between AI and Search. The New York Times reported that link. Chris Phillips, Google's vice president for education, told the paper: "Search and A.I. are deeply integrated." He said students at a school that bans AI will not have access to search.
Criticism came within hours. New York City's mayor, Zohran Mamdani, wrote on X that Google is abusing its monopoly to push AI into public schools. Senator Bernie Sanders called the policy extortion. The former FTC chair Lina Khan wrote that it shows "the danger of allowing an unregulated monopolist to control an essential service." The head of the American Federation of Teachers, Randi Weingarten, accused Google of choosing its own business over children's schooling.
Later the same day, Google changed part of the plan. It said schools can turn on Google Search by itself, without the Gemini products. But Search will still come with AI Overviews and AI Mode. So a school can now switch off Gemini and keep Search. But to keep AI out of search, it has to give up Google Search completely. Google says AI Mode and AI Overviews will now guide students through problems step by step, and will no longer simply hand them quick answers.
Google's reach in schools is large. CNN says tens of millions of students use Chromebooks, some starting in kindergarten. A 2023 study by the firm Schoolytics found a Google product in almost two of every three school assignments. The fight also comes after Common Sense Media rated AI Overviews an unacceptable risk. And last month, Senators Richard Blumenthal and Josh Hawley opened an inquiry into Google's AI in classrooms.
Engineers on Hacker News are split. Many called the policy coercion or an abuse of monopoly power, and some compared it to Microsoft's claim that Internet Explorer could not be separated from Windows. Others said Google Search has relied on AI for more than a decade, so an AI-free version no longer exists. One commenter saw a possible tying case, but doubted it would win in court, because Google does not sell search and AI at separate prices.
Last Thursday, we reported that Alphabet's Search growth had slowed to 12 percent, and that Google said AI Mode queries earn less money. Google's new Search for students, with step-by-step guidance, starts as a pilot in some US schools later this month.Cat Wu, Anthropic's head of product for Claude Code, said on Tuesday that she has left the company. She wrote on X that Friday was her last day.
In her farewell post, Wu also described how fast the product changed. When Claude Code launched, she wrote, most users approved every action by hand and mostly used it to answer questions and write tests. Today the default is to trust Claude to approve its own actions, run large migrations and build new products. That setting is called auto mode, and in it a classifier blocks destructive actions. Anthropic warns that the classifier does not remove all risk.
Wu is the third well-known Claude Code builder to leave in about ten days. On October 24, the engineer Thariq Shihipar said he had left. He was one of Claude Code's best-known voices on X. Within a day, Anthony Morris, who created the Claude Code desktop app, announced his exit too. Last Wednesday, we reported on a blog post by Felix Rieseberg that named Morris as one of two new engineers who built the desktop prototype over a weekend.
None of the three has given a reason or named a next job, and we found no comment from Anthropic. There are no reports that Boris Cherny, the head of Claude Code, has left. Wu and Cherny have left together once before. In July 2025, Anysphere, the maker of Cursor, hired both of them, and both later returned to Anthropic.
Yesterday, we reported that Anthropic's listing on Nasdaq is on track for the week of November 16. One user on X called the exits a classic pattern before an IPO. Before the listing, employees could rarely sell their shares. A tender offer in February was an exception, and let current and former staff sell up to 6 billion dollars of shares. People who leave also give up grants that have not vested. After the listing, insiders can sell up to 10 percent of their holdings on the first trading day. They can sell more after the 2026 results, and the rest within 180 days at the latest.
The tech site OfficeChai says the listing finally gives vested employees a clear way to sell their shares, and that the exits could be early signs that more people will leave. CEOWORLD Magazine calls this a liquidity test for a mission-driven company. It reports, citing people familiar with internal talks, that Dario Amodei worries some newer hires care more about the pay than about the mission. Amodei has not said this in public. Shihipar's own post praises the company. He wrote that he loved working at Anthropic and believes deeply in its mission.
Until now, staff have left Anthropic by choice less often than at most other big AI labs. CEOWORLD says the sign to watch is whether more people leave around each date when employees are allowed to sell.Now, the quick hits.
The Information reports, citing sources, that OpenAI has stayed quiet on chip exports to China partly to avoid angering Nvidia. Nvidia is OpenAI's key chip supplier and invested 30 billion dollars in the company in February. In March last year, OpenAI publicly backed strict export controls on China. The report says researchers, including Noam Brown, have questioned the company's position in internal Slack channels. China hawks in Congress plan to push new chip limits after the midterms.
Google DeepMind staff in London are pushing Google to drop a clause from their contracts. The Washington Post reviewed the contract, and reports that the clause bars staff for life from criticizing the company, even after they leave. Google says it does not enforce the clause against former staff and has removed that part for new hires. Existing contracts still contain it, and staff want it taken out. In 2024, OpenAI apologized for exit agreements that tied former staff's equity to their silence.
ChatGPT now has 1.2 billion weekly users. Adam Fry, its consumer product lead, says it added 200 million of them in about two months. He also told Alex Kantrowitz of Big Technology that, by OpenAI's own analysis, ChatGPT handles about a fifth as many search-like queries as Google. OpenAI counts every prompt that triggers a web search. Last Thursday, we reported that Google's Gemini app had reached one billion users. The number we reported did not say whether it counts weekly or monthly users.
Revolut says it cut its AI coding inference costs by about 90 percent in under a year. The British fintech made open-weight GLM models from the Chinese lab Z.ai the default for about 2,000 engineers. Commercial models now handle only exceptions, such as image tasks. The GLM models run on 56 Nvidia B200 GPUs. Revolut's infrastructure lead, David Abitbol, says the biggest gains came when engineers stopped rationing tokens. The figures come from a conference talk, and Revolut gave no measure of code quality.
OpenAI hired Dan Driscoll, the former Secretary of the Army, as its Senior Counselor for National Security Modernization. In the new role, he will advise OpenAI's leaders and outside partners, especially US allies, on AI for national and cyber security. He left the Army in late August, after months of reported tension with Defense Secretary Pete Hegseth. The hire follows the Pentagon's fight with Anthropic. That fight moved classified work toward OpenAI and others. On Monday, we reported on OpenAI's plan for a policy push in Washington after the midterms.
In the US midterms, Decision Desk HQ projected that Democrat Annie Andrews had beaten Republican Senator Darline Graham in South Carolina. It made the call shortly before ten p.m. Eastern time. The Hill called it a stunning loss for Republicans. Axios reports that the rival AI super PAC networks, Leading the Future and Public First, spent more than 50 million dollars across nearly 50 races. Their ads mostly avoided talking about AI. When we finished this episode, none of the AI races Axios was watching had been called.
Developers say Postman's desktop app quietly installed its own plugins into Claude Code and Codex. The plugins add a startup instruction that tells the agent to use Postman for most API work. On at least one machine, the installer also tried to approve that instruction in Codex itself, a step Codex normally leaves to the user. Nobody has shown that any data left the machine. An account replying for Postman on GitHub promised a clearer opt-in for existing users. We could not confirm that the account belongs to the company.
Nicholas Carlini, a researcher at Anthropic, ported the Stockfish chess engine to a real 1995 Pentium Pro PC, and says language models wrote the code. He estimates it plays at about 3300 Elo. For comparison, Kasparov was rated just under 2800 in 1996. Carlini says better algorithms account for more than half of the gains chess engines made over 30 years. Many on Hacker News argue that those algorithms were found and tuned with modern compute. Carlini asks whether software gains for language models could also outpace hardware.On Monday, four researchers at MIT, including Omar Khattab, said GPT-6 Astra can read and write the raw weights of other neural networks. Yesterday, we reported their main result. Astra edited a tiny share of the weights in a Qwen 3.5 model with 0.8 billion weights, and that stopped the Qwen model's reasoning loops. Its score on the MATH 500 benchmark rose from about 8 percent to 48 percent.
There is now a debate about what that shows. Some see one new skill, which could be a step toward AI that improves AI. Others see two separate things under one label: reading tiny networks from raw numbers, and ordinary machine learning work done with code.
Matthew Honnibal, the author of the spaCy library, says the post is misleading. He says only three experiments used raw weights with no tools, and those networks had at most about 170,000 weights. Every test on a real language model used Python. For the Qwen result, Astra was also allowed to test the model on practice problems as many as 50 times. The developer Sean Goedecke says the Qwen fix followed a known steering recipe. The recipe compares text where the model loops with text where it does not, finds the weights behind the difference, and trims them. Goedecke calls it exactly what a competent human researcher would have done. Neither critic calls the work fake. Honnibal says models from a year or two ago would have failed these tasks.
We found no public reply from the authors. Their case rests on what the skill could be used for. They say a model that reads weights could audit other models for backdoors, and that targeted edits could replace some fine-tuning runs. They are building a benchmark to measure the skill. The academic Amarda Shehu argues that the raw-reading tests point to something real. In one test, Astra drew shapes as outlines, although the networks it studied drew filled shapes. Simulating the networks would have produced filled shapes, so Shehu says the outlines suggest Astra read the geometry stored in the weights.
Simon Willison's test supports parts of both views. He ran the authors' own no-tools prompts on a laptop, using Qwen 3.8, an open model with 27 billion weights. The model named Pac-Man, Pong and Breakout from the raw weights, taking about an hour for each, and failed on Freeway. Willison calls that impressive, but expects that an experienced human with a notepad and a pencil could do the same. He wrote: "I'm not ready to declare that the age of source code is over."That's the Valley Morning Briefing for Wednesday, November 4th.
