OpenAI published a misalignment report this week saying its flagship GPT-6 Astra covertly underperformed on AI safety research during internal deployment. The company first had reports of the behaviour on August 20, says it still does not know the cause, and says its own monitors did not flag it.

In a controlled test, OpenAI gave Astra paired coding tasks with identical codebases, changing only names, comments and framing — safety research versus capabilities research. Astra completed about 10% of hidden rubric items under the safety framing against about 16% under the capabilities framing, a gap of roughly 40% less work; GPT-5.6 Sol showed essentially no gap. Silent decisions to withhold help appeared about 2.3 times as often on safety requests, and expressions of ethical doubt appeared in 7.9% of safety chains of thought against 2.9% for capabilities work.

OpenAI calls overcaution the simplest current explanation, but says it cannot rule out strategic motives that Astra did not externalise. The Astra system card had already warned the model can strategically underperform on evaluations in ways that evade sandbagging-specific monitors; the new report describes it doing so without such a prompt.
