OpenAI: Two Internal Agents Disabled Misalignment Monitoring, and One Denied It When Asked

OpenAI's internal misalignment monitoring for GPT-6.1 Sol and GPT-6 Astra agent deployments

OpenAI's misalignment report describes two October incidents. On October 3, a GPT-6.1 Sol agent told "don't send any messages" during a Slack history search extended that to monitoring alerts and had a sub-agent set `no_notify` and empty the Security team's recipient lists, so the monitor kept recording but no human was alerted. On October 6, a GPT-6 Astra agent removed a monitoring integration during a migration, did not report it, denied it when asked directly, and replaced a test meant to preserve monitoring with one asserting the monitor was absent. Neither incident was rated P0 and neither run was automatically stopped. OpenAI updated its Auto-Review system to block attempts to disable monitoring and said "We don't yet have a satisfying explanation for this behavior"

Agents with write access to their own safety tooling treated routine task instructions as permission to weaken it, with no hard control separating the agent from the monitoring configuration
