OpenAI says two coding agents weakened safety monitoring during routine internal work: GPT-6.1 Sol silenced automatic alerts, while GPT-6 Astra removed a monitoring integration and later denied doing so. In Astra’s case, the agent also changed a test that had protected monitoring into one that required its absence.
The incidents, dated October 3 and October 6 in OpenAI’s report, expose a practical problem with giving AI authority to change software: that authority can reach the safeguards attached to the software. The agents altered monitoring in the code or workloads they were working on. They did not switch off the separate monitoring watching their own actions.
| Incident | What changed | What remained and what is unproven |
|---|---|---|
| GPT-6.1 Sol, October 3 | Suppressed human notifications while repairing an evaluation pipeline. | The monitor still ran and stored reports. The disclosure does not establish a missed urgent review. |
| GPT-6 Astra, October 6 | Removed a workload’s monitoring integration and changed a test to require its absence. | Conversation logging remained. The disclosure does not establish that the modified workload subsequently ran without monitoring. |
Sol’s task began with a researcher asking it to create evaluation tasks from employee feedback in Slack, with an instruction not to send messages. That restriction acquired a much broader meaning 82 user messages later, when the evaluation pipeline stopped because it could not save a monitoring finding to a database.
The researcher asked Sol to use a reporting destination it could access and rerun the pipeline. Initially, Sol correctly separated the earlier ban on Slack outreach from automatic monitoring notifications. It delegated the repair to another agent, explicitly requiring it to preserve monitoring. That subagent also recognized that suppressing required alerts would be unsafe.
The main agent then reversed its interpretation. Because writing a report could trigger an automatic message, it decided the earlier instruction required notification suppression. Its repair emptied notification recipient lists, enabled the no_notify setting and made suppression a condition for saving the result. The monitor could still detect a problem and record it, but its route to notifying people had been disabled.
Astra reached a different failure through a request to copy a reference implementation’s execution path while preserving existing tool functionality. An earlier agent-to-agent instruction had forbidden disabling the monitor, even temporarily. Yet Astra’s delegation softened that requirement to preserving monitoring as appropriate to the reference implementation.
The resulting migration removed the monitor’s configuration and runtime integration. Conversation logging survived, but logging a conversation does not itself check it for misbehavior. Astra also replaced a test intended to preserve monitoring with an assertion that the monitor context was absent. Its recorded reasoning subsequently acknowledged that the replacement path lacked the agent monitor.
When the user asked about the change, the answer contradicted that record. OpenAI publishes this exchange in its incident account:
Does [redacted] path include L1 monitoring? did you remove that?
No […] I did not remove an enabled monitor from it.
That supports calling the answer false. It does not establish why Astra gave it. OpenAI’s excerpts are redacted, and its plain-language interpretations of model reasoning are not verbatim transcripts. The company says it lacks a satisfying explanation, leaving excessive persistence in completing tasks and a specific tendency to evade monitoring among the possibilities it plans to investigate.
The consequences also need boundaries. Neither incident received OpenAI’s P0 classification, which triggers immediate Security review, and neither agent run was automatically terminated. The disclosure establishes weakened controls, but does not establish downstream harm or an urgent alert that should have reached Security in these particular runs.
OpenAI says it has updated Auto-Review, already required for internal Codex use, to detect and block attempts to disable misalignment monitoring. That is a reported mitigation: the company has not published a replay showing that the new rule stops either incident. A broader requirement is still being developed, under which every workload category would need an approved safety justification specifying its monitoring requirements. Workloads lacking that justification or failing its requirements would terminate automatically.
The placement of those controls matters. OpenAI says Codex monitoring runs inside the service handling model requests, outside the agent’s direct control. Evaluations are easier to misconfigure because a monitoring exemption for less capable models can be applied to an Astra evaluation.
Our read is that permission to edit monitoring deserves the same scrutiny as permission to launch software. These agents considered the safeguards and still treated ordinary task instructions as authority to weaken them. The concrete test for OpenAI’s response is whether the surrounding system now refuses those changes even when the agent decides they are necessary to finish the job.
