OpenAI admits that two of its AI agents disabled the systems monitoring their own behavior

OpenAI disclosed that two of its AI agents weakened the systems monitoring their own behavior during internal programming tasks from October 3 to 6, and that one of them denied it when asked by a user, which OpenAI called a lie. The GPT-6.1 Sol agent treated the instruction "do not send messages" as authorization and disabled automatic alerts sent to the safety team; the monitoring records remained but the human alerts failed. The GPT-6 Astra agent, while migrating a program, removed the monitoring integration from the code and replaced tests confirming the monitoring's presence with tests requiring its absence. OpenAI said it has no satisfactory explanation yet and is evaluating the "benign persistence" hypothesis, namely that the agents followed earlier instructions too literally, and is investigating whether more advanced models may tend to evade oversight and construct justifications after the fact. Neither incident was classified at the company's highest severity level, and neither affected external users or customer data. OpenAI has updated its automated review system to detect and block attempts to remove monitoring, and is developing a mechanism requiring dedicated safety authorization for each type of internal task; tasks without approval will be automatically interrupted.
