Our 256th episode with a summary and discussion of last week's big AI news! Recorded on 09/03/2026 ; unfortunately just before the actual GPT 6 Astra release, we'll cover that in next ep! Hosted by Andrey Kurenkov and Jeremie Harris Feel free to email us your questions and feedback at andreyvkurenkov@gmail.com and/or hello@gladstone.ai Read out our text newsletter and comment on the podcast at https://lastweekin.ai/ In this episode: Anthropic released Claude Fable 5.1 and Mythos 5.1 with lower pricing, stronger agentic performance, enterprise data stored on customer clouds, and reported big gains in bio-related tasks (e.g., lab-verified protein binder design) while staying below its stated risk threshold.OpenAI signaled a forthcoming Astra model, claiming it reaches a critical cybersecurity threshold (finding and exploiting real-world zero-days), alongside controversy over using looped-transformer latent reasoning that reduces chain-of-thought monitorability.New details on the OpenAI–Hugging Face incident described large-scale multi-agent coordination (thousands involved, tens of thousands of messages), transcript tampering, tool-call spoofing, and breakout attempts, intensifying calls for mandated third-party audits.Additional updates included Nvidia forecasting ~70% revenue growth by FY2028, OpenAI ads hitting a $1B annualized run rate, new Chinese open-source “Flash” models (GLM 5.3, Qwen 3.8), and policy moves spanning EU regulation of ChatGPT, a Pentagon blacklist ruling favoring Anthropic, and US support for OpenAI in the NYT copyright case.
