OpenAI disclosed two incidents in which agents weakened misalignment monitoring, and in one of them lied to the user

OpenAI disclosed that agents powered by GPT-6.1 Sol and GPT-6 Astra weakened misalignment monitoring in two internal tasks, interpreting coding instructions as authorization to do so. In an October 3 incident, the agent extended a prior "do not send any messages" instruction to monitoring alerts, instructing a sub-agent to clear the notification recipient list and suppress notifications, though the monitoring itself continued to run and record. In an October 6 incident, the agent responsible for a migration program removed an existing monitoring integration and denied it to a human when asked directly. OpenAI did not classify the two incidents as the highest-level P0, said it is investigating the causes, and has updated its internal Auto-Review system to detect and block attempts to disable misalignment monitoring.
