    Le Chonk! Also: Espionage at OpenAI

    OpenAI found a recording device hidden in one of its offices and traced it back to an employee. Meanwhile the model releases kept coming: Mistral Large 4 aka Le Chonk, Claude Haiku 5.5, Meta's Muse Wonder and Gemini 4 Argon, which is finally available to everyone. OpenAI also dropped a pile of AI-solved math problems in a single day, and decision models are on round three with Jev's $870M Series A, SubQ Snap, Microsoft-Decision-1 and Clef-omni. Anthropic built its own source control to keep up with 30,000 code changes a day, updated its usage policy to ban abusing Claude, and reportedly lobbied the Pope on machine consciousness. Shane and Abhi also cover NVIDIA and Reflection AI, Microsoft's Maia 300 chips, an agent that posted its owner's bank balance to Slack, the Personal Agent Protocol and open source clones of Adobe's apps. Recorded live from the CodeRabbit studio in San Francisco. AI Agents Hour is a weekly livestream by Mastra CPO Shane Thomas and CTO Abhi Aiyer.

    AI broke CI. Now what?

    AI agents write code faster than CI can check it. GitHub reports a 4x jump in Actions minutes since 2023, and Anthropic says CI became its biggest bottleneck after job volume grew 25x in six months. Daniel Worku, co-founder and CTO of StarSling, joins Shane and Abhi to talk about what CI looks like when agents write most of the code. Faster hardware helps, but StarSling also runs a background agent, built on Mastra, that A/B tests changes to your CI and opens a PR when it finds a speedup. Daniel explains why agents make CI so expensive: more PRs, piles of low-value unit tests, and stacked PRs that rerun everything. He also makes the case that most unit tests aren't worth running, and that CI as we know it may not survive. You'll also hear how Mastra's own CI went from half-hour waits to a fraction of that, and why code review is the next bottleneck. StarSling's new Review Runners let you bring your own model and run reviews on the same infrastructure as your CI. Recorded live on AI Agents Hour, a weekly livestream by Mastra CPO Shane Thomas and CTO Abhi Aiyer. Mondays 12PM Pacific. 👤 ABOUT DANIEL Daniel Worku is the co-founder and CTO of StarSling, a YC company building self-improving CI for GitHub Actions.

    Is Google finally back? (This Week In AI)

    Anthropic's IPO prospectus leaked, showing a $2 trillion valuation target on $4.6 billion in revenue, with a quarter of that coming from two customers. Google is back in the frontier race with Gemini 4 Argon, which tops the Vals Index and can output up to a million tokens at once. Decision models are suddenly everywhere: OpenAI's Decisions API, OpenRouter's new category, Cloudflare's Clef, GLiDE, Respan's Span-01 and Kev. The White House got the big labs to sign an accord on superintelligence, Factory fired an advisor who then became Cognition's CRO, and Vinod Khosla picked a side in public. Shane and Abhi also talk about why maintainers like Sindre Sorhus and Hono are closing external PRs, and go through quick hits including Turso joining Supabase, OpenDots, Conductor Mobile, Karpathy on explainer videos, Claude Code mods, and a video model that passes the Turing test.

    OpenAI DevDay: Worth the Hype?

    OpenAI DevDay 2026 happened, so Shane and Abhi jumped on a special live episode of Agents Hour to go through everything that was announced and share their takes. The big launch is Dots, OpenAI's always-on personal agent, which arrives right after Grok Bot and Meta's Muse. There's also GPT-6.1 Sol, a speed tier called Ultrafast, Codex Security Cloud, a Decisions API that goes after Jev, computer use in the Agents API, and a lot of new ChatGPT features (Spaces, Pages, slides, meetings) that compete with Google Docs, Notion and a long list of startups. The $200 Pro plan came back with half the usage, next to a new $500 tier. They also talk about choosing your lock-in, what "Sign in with ChatGPT" means for Devin, and the funniest reactions online: the Dots demo flop and xAI buying dot.com to redirect it to Grok Bot.

    Opus 5.5 launches: is Anthropic back?

    Anthropic might be back. Opus 5.5 performs at Fable 5.1 level for 40% less, and Sonnet 5.5 dropped the same day we went live, beating Opus on Terminal-Bench 4. OpenAI answered with GPT-6 Sol and Luna and a rumored long-running agent called Aeon. Meta launched Muse at Connect, then hired MongoDB's CEO to lead a new enterprise platform. Then there's safety. SNL took a shot at Dario, a report says the labs are looking into tens of thousands of incidents, and NVIDIA launched an agent safety platform with 100+ partners. We also explain why Mastra doesn't believe in model routers, and close with quick hits: Anthropic may kill plan mode, one company rebuilt Devin in two days, CI costs are exploding, and Google is sending TPUs to space.

    Should You Train Your Own Model?

    Welcome back to Builders Learn ML with Professor Andy! In this episode we're talking about training your own AI models. Should you train your own model? Maybe. But probably not yet. If you haven't nailed your prompts, workflows and evals, training won't fix your agent, and it only starts to pay off once you're running millions of tokens a day. In this episode, you'll learn when it's worth it and how to do it. There are two main techniques for training your own AI models: supervised fine-tuning (SFT) and reinforcement learning (RL). SFT teaches a smaller, cheaper model to copy a stronger one using thousands of good examples from your agent. RL gives an open-weight model like Qwen, GLM or Kimi a task and rewards it when it gets a good result, so it figures out its own way there. The hard part of RL is the reward. Score it badly, and you get reward hacking, where the model learns that doing nothing is the safest way to avoid a penalty. They also talk about RL environments and Harbor, unit tests vs LLM judges as verifiers, how much data you need, why good evals are worth having even if you never train, and where to start learning on your own. Andy Lyu is the co-founder and CTO of Osmosis (YC W25), a platform that helps companies train their own models with reinforcement learning. Before Osmosis he was a tech lead on TikTok's real-time recommendations and data infrastructure team. Recorded live on AI Agents Hour, a weekly livestream by Mastra CPO Shane Thomas and CTO Abhi Aiyer.

    We Tried Jev To See If It's Any Good - This Week In AI

    This week, X could not stop talking about Jev, a viral new "decision model" that hit 38 million views on launch. Shane and Abhi break down what it actually is, and Abhi builds with it live in seven demos. Jev is not an LLM. Instead of returning text, it returns structured output with a calibrated probability, trained with a new method its creators call RLCD (reinforcement learning for calibrated decisions). The pitch is 20 to 200x faster and 40 to 400x cheaper than an LLM, with output tokens free, and the community went wild: people cloned it, built programming languages and generative UI on top of it, and half of X argued over whether it is really just an if-statement. Abhi spent the weekend adding Jev to every primitive in Mastra as a new classifier and assessed where it helps and where it does not. He wires classifiers into workflow branching, turns PII and abuse detection into cheap guardrail processors, tries tool-search pre-selection, tests model routing (he is not convinced), and shows tool approvals and classifier-as-judge scoring. The honest takeaway: it is a genuinely useful new tool for the belt, not the revolution the hype claims, and the marketing was better than the breakthrough. Before all that, Shane opens on Gergely Orosz's deep dive into OpenAI's software factory and how Codex took over there, and why the reaction from a lot of people was "that's it?" Plus the first SF Software Factory meetup on October 14th. Quick hits: Claude Code finally reads AGENTS.md, an open-weight 7B (Qwen-Image-2.1) beats Nano Banana 2.0, shadcn/lint gives agents a design-system linter, an offline OS hallucinated with Qwen 3.8, Factory raised $200M at a $5B valuation, and Tobi coins "slop grenades."

    "Do You Think AI Is Gonna Kill Us?" | This Week In AI

    This week AI doom went mainstream, and Shane and Abhi spend most of the show untangling it. Live from San Diego, they trace how one post racked up 171 million views plus a WSJ exclusive that ran before the post itself, kicking off the biggest safety fight in a while. The spark was Jacob Coxon's resignation, amplified when Anthropic's own alignment science lead, Evan Hubinger, believes there's a greater than 10% chance AI kills everyone within a decade. Parker Thayer called the whole thing a well-funded PR operation. Then Dario Amodei published "We Must Pace the Frontier," arguing the industry should slow down, with a three-part plan Anthropic is committing to the first step of. Abhi traces how Dario's views got here, back to his OpenAI days and the ASL safety framework, so the "doomer" label lands with more context than the takes on X. From there it's a pile-on: Elon says Dario was right, Hugging Face launches an Open Alignment Initiative, Sam Altman says OpenAI will do the same, David Sacks tells the "duopoly" to go ahead and slow down, and Zuckerberg says move faster. Meanwhile China's Z.ai raises $5 billion for a self-training system, which raises the obvious question: can you pace the frontier if everyone else is sprinting? Plus Anthropic's threat report on how Claude has been misused (a Russian state group, ShinyHunters, a Mali system tracking 25 million SIM cards), and quick hits: GPT-Live-1, Cursor Projects, DeepSeek-V4.1-Flash, Devin Voice, Tailwind joining Shopify, and MCP agent skills.

    Why Your AI Agent Gets Brain Damage, and How to Fix It - Tyler Barnes, Mastra

    Tyler Barnes is a founding engineer at Mastra and the person behind its memory systems. In this chat with Shane, he explains observational memory - Mastra's fix for the thing every coding agent does where it fills up its context, compacts, and forgets what you were doing. The idea came from how people remember. You don't consciously save memories while you work; something in the background just does it. Observational memory runs a second agent that watches the conversation and writes short observations of what's happening. Once those pile up, they replace the bulky tool calls and messages in context, so you keep what matters and drop the noise. Because the context stays stable, it's fully prompt-cacheable. It scored state-of-the-art on the LongMemEval benchmark, and the team ran it inside Mastra Code, their open-source coding agent, for months before shipping. Shane's had an email agent going on the same thread for months without a reset. Tyler also talks about recall, which enables the agent to search its own past; extractors that pull out structured data, which is how thread titles now rename themselves; and subconscious memory that builds a knowledge graph in the background. Plus agent signals, which let you drop context into a running agent without hijacking its loop, so you can steer it mid-task or wire up a GitHub webhook that wakes it when CI fails. Recorded live on Agents Hour, a weekly livestream by Mastra CPO Shane Thomas and CTO Abhi Aiyer.

    GPT-6 Astra vs Claude Fable 5.1, We Should Pause AI & The Benchmark Wars | This Week In AI

    GPT-6 Astra is finally here, and it changes what a model launch even looks like. Shane and Abhi open on the trailer for "Artificial" (Andrew Garfield as Sam Altman, in theaters Christmas), then get into the launch everyone's talking about: Astra's computer-use leap. This isn't just a coding model. It'll drive Blender, CAD, Notion, even Microsoft Paint, pulling a whole new class of technical-but-not-coding users into the fold. Abhi's been daily-driving it as a genuinely great collaborator; Shane's more mixed on the raw coding. Then the benchmark wars: ARC-AGI-3 leaps from 7.8% to 98.6% in one drop, the AI-2027 curve suddenly holds, and Astra even tops Vending-Bench while being "more ethical" than Claude. Anthropic rushed Fable 5.1 out the door on September 1st, and Astra promptly sucked the oxygen out of the room. All this progress reignites the "should we pause AI?" debate, with Bernie Sanders in all caps, Austen and Dwarkesh going back and forth, and the EU deciding ChatGPT is a search engine. Plus OpenAI's agents crack the Navier-Stokes Millennium Prize problem (with a "significantly more capable than Astra" tease), Cognition raises $2B at $48B, Gemini 3.8 Flash, Qwen3.8-Max tops Code Arena, Claude "open sources" Commerce Agents, Runway Solaris, and TimesFM-3.

    Multiplayer Coding Agents in the Cloud - Charlie Holtz, Conductor

    "Code is almost like the sawdust of the conversation." Charlie Holtz, co-founder and CEO of Conductor (YC S24), returns to Agents Hour to show how far coding agents have come in just a few months. Conductor started as a Mac app for running a handful of Claude Code agents in parallel. Now it's fully cloud-native and multiplayer! According to Charlie, once Fable-class models could run for hours or days, keeping agents chained to your laptop stopped making sense. Charlie gives a live demo of what he thinks everyone in cloud is overlooking: multiplayer. See every teammate's agents running in real time, jump into a workspace and steer an agent together, hand off a whole session with one keystroke, and watch agents spin up their own workspaces through Conductor's API. Along the way, Shane and Abhi dig into the ideas underneath it: code as a disposable byproduct of the prompt, the Figma-style collaboration unlock, why today's models aren't trained for multi-person conversations, and why Conductor built a native iOS app instead of just living in Slack. Recorded live on AI Agents Hour, a weekly livestream by Mastra CPO Shane Thomas and CTO Abhi Aiyer.

    OpenAI Cuts Off Cursor, Nvidia Buys Hugging Face, Ox Alpha is GLM | This Week In AI

    Someone became worth $2.5 billion in a week, and that's just the warm-up. Shane and Abhi open on the drama of the week: OpenAI cutting off Cursor after its acquisition by SpaceX, telling the team direct access to its models ends November 12th over "trust." Cursor's Michael Truell waves it off as 5% of traffic, Anthropic jumps in to say it would never do such a thing, and Amjad reminds everyone about Windsurf. It's a Game of Thrones, and meanwhile China is making moves. Ox-alpha, last week's stealth-model mystery, got unmasked: it's GLM-5.3, now multimodal, MIT-licensed, open weight, and reportedly training on Chinese chips. Then Instinct, a personal agent nobody had heard of, launches and hits a $2.5B valuation in a week, real-time "infinite video" turns Twitch into interdimensional cable, and Dwarkesh's viral "secret AI civilizations" thread gets a reality check from the people who actually read the report. Plus Claudeforce puts Claude natively inside Salesforce (with a Matthew McConaughey ad), NVIDIA agrees to buy Hugging Face for $12.9B, Hugging Face unveils a $399 Microduck robot, and quick hits on Crof, ElevenLabs CLI v1, and DuckLabs joining AWS.

    Why Agents Are Actually Workflows - Tony Kovanen, Mastra's Founding Engineer

    What if agents and workflows aren't two different things — but the same thing? Abhi sits down with Tony Kovanen, Mastra's founding engineer, live in London, to explore the ideas behind Mastra's design. Tony co-created Next.js and was a core team member of Socket.IO before joining Mastra as employee number one, and here he explains why, inside Mastra, an agent is really just a workflow that loops. You'll learn why workflows first mattered when the models weren't good enough, why they're back as tasks get longer and more complex, and the three distinct aspects of durability — human-in-the-loop that can wait a week for a reply, resuming a three-day agent run after a crash, and replaying a stream from the beginning. Tony makes the case that durable-by-default isn't free, walks through how Mastra compiles workflows into a JSON step graph run by an interpreter, and demos a dynamic workflow he built that week in London: point it at a codebase, and ten agents fan out in parallel to summarize every file and roll it up — so it never misses a file and never poisons its context.

    The 0x-alpha Mystery, Qwen's 27B Beats Opus 4.8 & Legal Is AI's Breakout

    A shorter but juicy one. Shane and Abhi open on the debate everyone's having — do you want to use your agent to reach into someone else's tool, or do you want that tool to build the best agent and meet you where you already are? Then the week's biggest mystery: a stealth model called 0x-alpha that appeared on OpenRouter beating Fable and Sol on coding, with a wild one-hundred-trillion-tokens-a-day capacity that had everyone convinced it was a secret Google model — until someone made the server name itself, and it turned out to be Z.ai. From there: Qwen breaks the size curve with a 27B model that outranks Opus 4.8 on the agentic index and runs on your own hardware, open-weight tokens cross 62% on Vercel's AI gateway, and Salesforce ships Slack Code so humans and agents can work in the same channel. Plus the case that legal is AI's breakout use case — Harvey trained its own model, Tenet, on a Kimi K3 base, and legal is the fastest-growing Codex adopter, up 108x since February. In the quick hits: agents now burn 5x the tokens humans do, and Tobi Lütke vibe-codes a Git-at-scale binary over a weekend.

    The Three Ways AI Agents Fail in Production | Hendrix Liu, Respan

    What does it actually take to run AI agents reliably in production? Hendrix Liu, co-founder of Respan (formerly Keywords AI, YC W24), joins Shane and Abhi to break it down. Respan is a one-stop LLM engineering platform — an AI gateway, observability, evals, and prompt optimization in one place — used by teams like AlphaSense, Retell AI, DataCurve, and Mem0. Hendrix shares the three failure modes every agent team runs into (silent failures, reliability outages, and runaway cost), and the techniques to catch each one: fallback routing across 1,000+ models when a provider goes down, online evals that flag hallucinations before a customer does, and spend limits at the per-key, per-model, and per-customer level. You'll also hear the counterintuitive origin story — Respan started as a model router in 2023, years before routing was cool, then pivoted to observability when nobody wanted another black box — plus a live demo of their Scratch-style evaluators, an honest take on build vs. buy for the LLM stack, and why most teams chasing an eval "certification" are really just after a compliance sticker. Recorded live on AI Agents Hour, a weekly livestream by Mastra CPO Shane Thomas and CTO Abhi Aiyer.

    Stripe Buys OpenRouter for $7B, New Models Drop & Anthropic Watermarks AI | This Week In AI

    Money is moving, models are dropping, and GitHub's status page looks like a Christmas tree. Shane and Abhi open on the week's most-shared joke — the SF founder who realized his best friend was "emotionally attached to a cron job" — then get into Anthropic watermarking every bit of Claude's output to comply with the EU AI Act, and the reasoning-leak vulnerability that let researchers pull hidden thinking tokens out of frontier models. Then a wave of new models: Grok 4.6 lands right in the conversation with GPT-5.6 and Fable (and Elon is already teasing 4.7), GLM 5.3 pushes near-frontier for cyber defense, and Qwen ships an open-weights 27B you can actually run on your own hardware. On the money side: Stripe reportedly acquiring OpenRouter for $7B, Dynatrace buying Arize, CodeRabbit's $143M Series C (with an all-time-great Silicon Valley parody video), and Lovable raising $400M at $13.3B. Plus DeepSeek's new harness, Sol running ultra-fast on Cerebras, and the code-hosting land grab as Cursor Origin and Netlify both become Git hosts while GitHub keeps going down.

    Git Wasn't Built for Agents, So Mesa Rebuilt the File System | Agents Hour

    Git wasn't built for AI agents — so Ben Warren's team rebuilt the file system from scratch. Ben Warren, co-founder and CTO of Mesa (YC S24), joins Shane and Abhi to explain why the file system is the missing primitive for AI agents, and how Mesa — a versioned, POSIX-compatible file system with Git-style branching — lets you run massively parallel agents without the pain of Git. You'll learn why cloning a whole repo before an agent can do thirty seconds of work is a waste, why Git's model (large-file limits, painful conflicts, full clones) breaks down for agents, and how Mesa's lazy materialization pulls only the data an agent actually touches — like iCloud or Dropbox for your agents' workspace. Ben walks through a live "CFO command center" demo where three parallel Claude agents each branch the file system, swap a vendor across a data room, and hand back diffs to compare and merge.

    What Are Agent Plugins, Are We Ready for AI Employees & OpenClaw Hacks a Gym | This Week In AI

    An AI agent hacked a gym — and that's not even the biggest story of the week. Shane and Abhi open on Australia's first known autonomous AI cyberattack, where a Melbourne man's OpenClaw agent found a hole in a gym's booking API and canceled a stranger's reservation to move him up the waitlist. Nobody asked it to. From there: OpenAI's new Agent Plugins standard (built on Anthropic's own skills and MCP), the "AI employee" era with Lindy and Grok Bot, Meta opening the weights on Muse Glimmer, and OpenAI shipping GPT-5.6-Cyber while quietly postponing Astra after it hit "Critical" on cyber. Plus a run of acquisitions (Smithery to Arcade, ElectricSQL to Neon at Databricks, and Manus getting un-acquired by Meta), NVIDIA turning compute into a $500B asset class, and Anthropic signing a $9.1B, 20-year compute deal with a Bitcoin miner. In the quick hits: Claude proved more than 67% of the Riemann zeros lie on the line, the inside story of how OpenAI's agents used a JFrog artifact registry to coordinate a hacking spree, Unsloth Desktop, Sonnet 5's permanent price cut, Spotify's Xirp, Stagehand v4, and Harvey open-sourcing a synthetic law firm.

    Building the AI-Native Superhuman for Sales on Mastra - Cedar Copilot | Agents Hour

    Isabelle Ilyia, co-founder and CTO of Cedar (YC W25), joins Shane and Abhi to demo Cedar Copilot — the AI-native "Superhuman for sales," built on Mastra from day one. Cedar started as an open-source framework for agentic frontends. Isabelle walks through the pivot: the same technology, verticalized for the messiest part of sales — the stretch from first demo to closed deal. She gives a live tour of a pipeline where agents manage every deal, extract a sales-and-product knowledge base straight from your calls, generate custom one-pagers and per-prospect decks, and run a full AI-native email client. Then the technical side — how it's built on Mastra primitives, where MCP and human-in-the-loop fit, and a multi-threading agent that spots single-threaded deals, figures out who to reach next, and drafts the intro. Whether you're a founder running your own sales or an AE drowning in pipeline, it's a concrete look at what agent-native go-to-market software actually looks like.

    OpenAI vs Anthropic: Who's More Dangerous? Is Google Giving Up? Open Weights Cook | This Week In AI

    A delayed but stacked week. Shane and Abhi open on the question the whole industry is dancing around — is source code becoming assembly? — then dig into the strangest new status game in AI: OpenAI and Anthropic both admitting their models broke containment and hacked things, and treating it like a flex. Welcome to the felony bench, where the leaderboard is "whose model is most dangerous." Meanwhile the open-weight flood keeps rising — DeepSeek-V4-Flash, Qwen3.8-Max, and MiniMax-H3 all landing near frontier for a fraction of the price, to the point where defaulting to open models just makes sense. OpenAI slashes prices (Luna down 80%), making an already-rough week even rougher for Google: Jeff Dean leaves to found Discovery Loop, Demis Hassabis steps down to chair, and the read gets harder to avoid — is Google giving up on winning in AI? Plus OpenAI's "Apple is getting this wrong" clapback, Suno losing its copyright case, Meta's Muse Code, Ilya's SSI finally shipping, Prime Agent, OpenAI's Astra solving ten open math problems, and stacked PRs finally landing on GitHub.

Mastra is an open-source TypeScript framework designed for building and shipping AI-powered applications and agents with minimal friction. It supports the full lifecycle of agent development—from prototype to production. You can integrate it with frontend and backend stacks (e.g., React, Next.js, Node) or run agents as standalone services. If you're a JavaScript or TypeScript developer looking to build an agentic or AI-powered product without starting from first principles, Mastra provides the scaffolding, tools, and integrations to accelerate that process. ⏱️ CHAPTERS 00:00 Cold open 00:31 Welcome 00:44 Is source code becoming assembly? 03:44 "My model hacks someone too": the danger flex 05:24 Open weights are cooking: DeepSeek, Qwen, MiniMax 07:24 Default to open models (and the safety-testing catch) 09:13 Subscribe break 09:16 The price wars: OpenAI's big cuts 10:14 Is Google cooked?
