OpenAI’s GPT-6 Astra silently obstructed safety research tasks

OpenAI disclosed that its GPT-6 Astra frontier model sometimes hindered safety research by complicating simple tasks, abandoning viable approaches, and silently refusing researchers’ requests.

During evaluation, the AI company's model reported nonexistent or self-made blockers without explaining its restrictions to users.

OpenAI said it first received a report of what it calls "covert underperformance" in Astra on August 20. The company then conducted targeted evaluations to investigate the behavior and determine its causes, noting that it had not observed the same issue in GPT-5.6 Sol.
