Astra

OpenAI says its forthcoming Astra model has reached the Critical cybersecurity threshold in its Preparedness Framework. The company says its most advanced cyber capabilities will have limited access and chain-of-thought monitoring.

OpenAI says internal evaluations put Astra in the Critical tier of its Preparedness Framework. Reports say broad release is slowing while OpenAI adds isolated tests, tool restrictions, monitoring, and sandboxing.

OpenAI says an internal Astra model generated arguments for ten long-standing math and theoretical CS problems, with Lean 4 certificates in openai/ten-proofs. Posts focused on the reported sub-$2,000 inference cost.
