OpenAI Caught a Spy! Plus Mistral Le Chonk & Claude Haiku 5.5

A recording device turned up hidden in OpenAI's office, and OpenAI's own models led the search for the employee who planted it. That spy story opens this week's AI Agents Hour with Shane and Abhi. This week's model releases include Mistral Large 4 "Le Chonk," Claude Haiku 5.5, Meta's Muse Wonder, SubQ Snap and the global release of Gemini 4 Argon. OpenAI's big math drop also gets a closer look: 81% of the AI discoveries on Will Depue's chart arrived in a single day, and three have since been withdrawn. Decision models are back in the news with Jev's $870M Series A, Microsoft-Decision-1, and Unsloth support for training your own decision model on 8GB of VRAM. From Anthropic: in-house source control built for more than 30,000 merges a day, cheaper cache reads, a usage policy that bans abusing Claude, and Chris Olah taking the question of machine consciousness to the Pope. Quick Hits: Grok Bot running on Claude, an agent that posted its user's finances without being asked, and free AI-built clean-room clones of Adobe's apps. 📚 MASTRA RESOURCES https://mastra.ai https://x.com/mastra_ai https://mastra.ai/community/discord https://github.com/mastra-ai Learn Mastra: https://mastra.ai/learn https://mastra.ai/books/principles-of-building-ai-agents https://mastra.ai/books/patterns-of-building-ai-agents WHAT IS MASTRA Mastra is an open-source TypeScript framework designed for building and shipping AI-powered applications and agents with minimal friction.
