Astra

Astra's Elo fell during Peter Gostev's chess test, where agents can take notes and choose opponents. Later results suggest Opus improved, and GPT-6.1 Sol and Fable were added to the benchmark.

Kevin Kern's single-task comparison favored Astra coordinating Opus 5.5 for quality. Solo runs were close, cost less and finished about three times faster; a rerun corrected for polling costs.

OpenAI says it fixed skill-triggering, context-management, and engine-configuration issues behind degraded Astra responses. The reset is now rolling out across Codex and ChatGPT Work.

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.
