OpenAI's Astra is the first model ever assessed as reaching "Critical" cyber capability under the company's Preparedness Framework — able to find and exploit previously-unknown zero-days in hardened systems and plan/execute end-to-end cyberattacks from only a high-level goal, without step-by-step human guidance. This episode digs into what that threshold means, how a capability like this gets evaluated and gated, and why Astra still ships — just with tightened access controls and monitoring rather than staying on the shelf.
