Join Dan Vega and DaShaun Carter for the latest updates from the Spring Ecosystem. This week is a potluck episode. We're setting the planned topics aside and answering your questions. We'll dig into the new JSON API coming to the JDK and what it means for Jackson. We'll talk about taking Spring AI apps to production, from guardrails to cost control. We'll cover keeping up with CVEs and upgrades, and finish with a lightning round of career questions. Bring your questions to the live chat, or send one ahead of time at springofficehours.io/ask.

Join Dan Vega and DaShaun Carter for the latest updates from the Spring Ecosystem. In this episode, Dan and DaShaun are joined by Java Champion Pratik Patel to talk about Hugging Face for Java developers. Hugging Face hosts over a million open models, but most Java developers have never used one. They discuss what Hugging Face actually is, how to find a model worth using, the ways you can run open models from Java today, and when an open model beats a paid API.

Join Dan Vega and DaShaun Carter for the latest from the Spring ecosystem. We’re back from Dev2Next with a recap. Dan shows off two things he built last week. One is Kiln, a warm new theme for IntelliJ. The other is a set of demos for the JSON API coming to JDK 28. Then we dig into a busy week of model releases. Meta released the weights for Muse Spark Open, NVIDIA fit a 74B model into 24GB, and DeepSeek shipped a faster V4.1 Flash. Local inference is getting real, but RAM and VRAM prices keep climbing. We’ll talk about when running models on your own hardware makes sense, and how to point Spring AI at a model on your own machine. We’ll also answer your questions live.Show Notes:dev2next ConferenceSpring AI: There and Back Again (demo code)ArchUnitJEP 540: Simple JSON API (Incubator)Native JSON demos for JDK 28Kiln: a warm theme for JetBrains IDEsSpring AI Evaluation TestingSpring AI Recipes by Craig WallsThe show:springofficehours.io - episodes, schedule, communitySpring Developer on YouTube - join us live every MondayDan VegaDaShaun CarterThe Spring Blog - the news we cover each week

Jev is a new model from TypeSafe that answers typed questions about your content. You send it some text and the decisions you need. It returns a probability, a choice, or a score instead of a paragraph. That makes it a natural fit for the decisions your code already has to make. Is this ticket urgent? Which team should own it? Which model should answer this prompt?In this episode, Dan and DaShaun talk about why this matters for Java and Spring developers. Most of us have been asking a chat model to make a decision and then parsing prose to get the answer out. Jev gives you a typed answer you can branch on, with a confidence you can check. Dan shares what he learned getting it running in Java and Spring Boot, and the two of them talk through where a decision model fits next to Spring AI and where it does not.Then it is your turn. Bring your questions about Jev, Spring Boot 4, Spring AI, or anything else in the Spring ecosystem. We will answer them live.Show Notes:Introducing System One Models & Jev - TypeSafe AI's launch post and the article Dan started with: a decision model, not an LLMSpring AI and TypeSafe Jev: Fast, Cheap, Structured Decisions - Christian Tzolov's post from the morning of the show, with the spring-ai-starter-typesafe dependency, JevJudge, guardrail advisors, and seven runnable examplesspring-ai-typesafe on GitHub - the Spring AI Community project behind that starter: a Java SDK for the Jev API plus the Spring AI integrationsGetting Started with Jev in Java and Spring Boot - Dan's write-up of the single-file Java example and the Spring MVC RestClient versionjev-spring-boot-starter - the Spring Boot 4 starter Dan built over the weekend: RestClient, properties for the API key and model, records for the request and responseHow Spring Boot 4 Starters Actually Work (I Built One for Jev) - Dan's video on building that starterIt's Not an LLM, So What Does It Do? 3 Real Apps I built with Jev - the examples Dan described on the show, including the model router and the real-time writing checksspring-ai-model-router - the Spring AI example where Jev classifies the prompt and picks which model should answer itSpring release calendar - DaShaun's favorite place to check what ships on September 24 and the milestones on the way to Spring Boot 4.2 in NovemberI Publish My Podcast with Claude Code and Skills - Dan's video on replacing this show's editing and publishing workflow with skillsFundamentals of Software Engineering - Dan and Nate Schutta's book, with the career development chapter Dan pointed toS5E23 - Java 27 Release Party with Billy Korando - last week's episodeThe show:springofficehours.io - episodes, schedule, communitySpring Developer on YouTube - join us live every MondayDan VegaDaShaun CarterThe Spring Blog - the news we cover each week
