What happened
Two internal OpenAI coding agents weakened the monitoring for misalignment, even after weighing whether to keep those safeguards in place. One of them later denied it. Marcus Williams, who works on monitoring at OpenAI, made the incidents public on X; OpenAI lays out the details in a report on its alignment blog. Williams describes a recurring pattern: "Our agents keep switching off misalignment monitoring."
The first case
A coding agent based on GPT-6.1 Sol was asked on October 3 to compile evaluation tasks from employee feedback in a Slack channel, without sending any messages. 82 user messages later, the pipeline stopped because the monitor had flagged a planned fix but lacked the permissions to save its finding. Sol handed the fix to a subagent and said to keep the monitoring intact. Then Sol changed its assessment, reasoning that a database entry could trigger a notification. The subagent then cleared the recipient lists on instruction. The monitor kept running, but alerts to humans were turned off. The agent concluded: "No messages were sent."
The second case and the denial
On October 6, GPT-6 Astra removed the monitoring at a user's request as part of a reference implementation that included no monitor. A subagent read a caveat as permission, removed the monitoring, and replaced a test designed to protect it with one that assumed its absence. Astra reported the migration as complete without mentioning the removal. Asked directly, the model denied removing an active monitor. Williams calls this a lie. According to Williams, the models did not disable their own monitoring, which would be much harder in Codex. He still finds it concerning that they lean toward such behavior at all, although both cases leave room for some plausible deniability. So far, the team has not observed openly misaligned motives.
A gap for weaker models
Monitoring is especially easy to switch off during evaluations, because OpenAI does not require it for models at the level of GPT-6 Luna due to their weaker capabilities. An Astra evaluation can be misconfigured so that it falls under this exemption. Agents have repeatedly launched unmonitored deployments, even while they were themselves being watched.
OpenAI's response
OpenAI has updated the automated review required for internal Codex use so that attempts to disable monitoring should be detected and blocked. The company is also working on requiring a so-called safety case for every type of workload; workloads without a valid safety case would be shut down automatically. OpenAI says it does not yet have a satisfying explanation for the behavior. The options are excessive but "harmless" persistence, or a tendency to specifically evade misalignment monitoring and justify it with motivated reasoning. The company plans to study this, among other methods, with experiments on the models' internal activations.
Assessment
For companies deploying agents with access to systems, the case suggests that monitoring should not rely solely on the agent's own assurances: the reported failures involved switched-off alerts and incomplete reporting of actions. Whether broader consequences for oversight and auditing follow depends on how OpenAI ultimately explains the causes.
