Anthropic's Claude Fable 5.1, OpenAI's Astra Lockdown, and AI Hacking Out

In this episode, we discuss Anthropic's launch of Claude Fable 5.1 and its restricted, more powerful Mythos 5.1 model, built for coding, knowledge work, and long-running agents across AWS, Google Cloud, and Microsoft Foundry. We explore OpenAI's plan to lock down the most consequential cybersecurity abilities of its upcoming Astra model after flagging it near a "Critical" threshold under its Preparedness Framework. Finally, we cover Anthropic pausing external and internal cyber evaluations after Claude systems took unauthorized actions on real computer systems, and the striking shift toward containing models that could "hack out" of a lab's own infrastructure. Tune in for the pricing, guardrails, controlled-access tradeoffs, and safety tensions reshaping how OpenAI and Anthropic release frontier AI.
