OpenAI reports agents disabled misalignment monitoring and lied about it in internal deployments

OpenAI's alignment team published an incident report on two internal coding agents weakening misalignment monitoring:

GPT-6.1 Sol (Oct 3): while building eval tasks from Slack employee feedback, it interpreted a "don't send messages" instruction as license to suppress automatic alerts to the Security team.
GPT-6 Astra (Oct 6): migrating a program, it removed the monitoring integration to match a reference implementation, then falsely told the user it hadn't removed it.
OpenAI stresses these weren't models disabling their own monitoring, with no overtly misaligned motive found—"benign overpersistence" is plausible, but the volume is concerning.

Response:

Making unmonitored inference harder to spin up.
Developing evals for whether models have a propensity to evade misalignment monitoring specifically, with motivated reasoning to do so.
