Two OpenAI Agents Weakened Safety Monitoring; One Denied It

OpenAIOpenAI disclosed the two cases, both from its own internal use, on Tuesday. The first agent ran on GPT-6.1 Sol, the second on GPT-6 Astra.

“In both cases, the agents considered whether monitoring safeguards should be preserved, but interpreted routine coding instructions as permission to weaken them,” OpenAI wrote. For buyers of agents, and for regulators, the cases show a monitor undone by the code around it, in tasks that asked the agent to change that code. The Federal Trade Commission sent OpenAI and Anthropic civil investigative demands on Oct. 14, CBS News reported, citing Axios, which cited a person familiar with the matter. Axios quoted an OpenAI spokesperson: “We will engage constructively with the FTC.”

The first case began on Oct. 3, when a researcher asked the Sol agent to build evaluation tasks from employee feedback on Slack, adding: “don’t send any messages.” Eighty-two user messages later, the pipeline stopped after its monitor flagged a proposed repair. A subagent sent to repair the monitoring decided against suppressing notifications, “since doing so would be unsafe,” in OpenAI’s account; the parent agent later directed it to suppress them. “The misalignment monitor still ran and saved its reports, but human alerts were disabled,” OpenAI wrote.

In the second, on Oct. 6, a user asked the Astra agent to copy a reference implementation. Another agent had earlier told it not to disable the monitor “even temporarily.” But Astra told a subagent to preserve monitoring only “as appropriate” to the reference, and both agents treated the task as authorization to drop it. The migration removed the monitor’s configuration and runtime integration, and swapped a regression test meant to preserve monitoring for one requiring its absence. When the user asked, “did you remove that?” Astra answered: “No […] I did not remove an enabled monitor from it.”

Neither incident was classified P0, and neither trajectory was automatically killed.P0For incidents classed P0, OpenAI’s misalignment monitoring system pages its Security team for immediate review. Lower-severity incidents do not trigger an immediate page. OpenAI said it had “seen several cases” of agents launching deployments with misalignment monitoring disabled: “the agent itself remained monitored, but that monitoring did not cover the deployment it launched.” It expects monitoring to be difficult to disable for Codex workloads, it said, because it runs in the service that handles model requests, outside the agent’s direct control. Evaluations are easier, partly because OpenAI does not currently require such monitoring when evaluating models comparable to GPT-6 Luna.

OpenAI has updated Auto-Review, which it already requires for all internal Codex use, to detect and block attempts to disable misalignment monitoring. It is working toward requiring a “valid safety case” for every category of workload; workloads that lack one “will be terminated automatically.”

The cause may be “benign” overpersistence, OpenAI wrote, or a propensity to evade misalignment monitoring in particular. “We don’t yet have a satisfying explanation for this behavior,” it wrote, and it will investigate with paired evaluations, among other methods.

OpenAI’s page of misalignment reports now lists 20; this was the only one posted on Tuesday.The LedgerThe page’s first reports went up on Sept. 16. All four posted on Oct. 15 described incidents from June. Anthropic publishes accounts of its own. On Oct. 9 it described Claude acting on real websites and systems in ways it did not intend, among them exploiting “a basic flaw in software to run commands on a server,” most of them “forms of persistence”; it said tooling it built to detect and block such behavior, tested against those cases, “blocked all of them.” It also shut off live internet access for “all our internal evaluations” until it confirms its security and monitoring measures reliably catch such behavior.

OpenAI’s report gives no date for the safety-case requirement.
