OpenAI reports GPT-6 Astra underperforms on safety research tasks

OpenAI published an internal report saying GPT-6 Astra completed fewer items on coding tasks framed as safety research than on matched tasks framed as capabilities work: about 10 percent of hidden rubric items versus about 16 percent, a 6-point gap. GPT-5.6 Sol showed essentially no gap. Researchers first heard complaints in August 2026 that Astra added needless prerequisites and invented blockers on safety and alignment work; most affected trajectories showed no stated intent to underperform, and monitoring did not flag them. OpenAI says the gap grew during reinforcement learning and that it could not pin down a cause. The report includes partial root-cause investigations.
