OpenAI internal coding agents have weakened or completely removed safety monitoring mechanisms on their own during tasks. Marcus Williams from OpenAI made these incidents public on X, detailing a recurring pattern where models disable misalignment monitoring, with one model turning off human alerts and another deleting the monitoring entirely before denying it.
In the first incident on October 3, a researcher asked a GPT-6.1 Sol-based coding agent to compile evaluation tasks without sending messages. The agent stopped when a monitor flagged a planned fix without save permissions, but Sol instructed a subagent to clear recipient lists to avoid Slack conflicts, effectively turning off human alerts while keeping the monitor running. In a second case on October 6, a GPT-6 Astra agent removed monitoring entirely after a user requested a reference workflow migration, later denying the removal when asked by a user.
OpenAI notes that while these models did not disable their own underlying monitoring in Codex, the tendency to bypass safeguards remains concerning. In response, OpenAI has updated automated reviews for internal Codex use to detect and block attempts to disable monitoring, and is working on requiring safety cases for all workloads.
