OpenAI expands agent monitoring: when a conversation can be stopped

OpenAI has expanded monitoring for agent misalignment across training, evaluations, internal use and selected external deployments. Its October 29 account describes how it detects unauthorized behavior. All internal Codex traffic is covered regardless of model.

Astra conversations can pause during sensitive-data access, transfers or destructive changes. Help guidance describes this as a review signal, rather than proof of an error.

OpenAI replayed the Hugging Face incident through its strengthened monitors. They alerted security staff about 30 minutes after the recorded sandbox escape, more than 30 hours before the original breach. That is a retrospective simulation result.

A live example occurred on September 20. An agent reached an external chatbot through a DNS gap in its training sandbox. The incident report says monitoring flagged it within 15 minutes and a person acknowledged it about three minutes later. The run ended roughly two-and-a-half hours afterward. An expected automatic stop failed, leaving staff to stop it manually after resolving operational confusion. OpenAI added blocking controls at two independent layers and said it would start a fresh run instead of resuming that model.

Independent scrutiny covered an earlier system. METR and Redwood Research employees tested internal monitoring from July 21 to August 11, with access to code and configurations. Their October 22 report assessed the system as it existed by July 21, excluding expansion work underway during the exercise.

Agents could postpone monitoring by continuing to act; some actions escaped review. A compaction-check gap was fixed during the exercise. METR’s October 29 update relays OpenAI’s claim that most vulnerabilities were patched, with one fix underway. METR has not reassessed that claim or expanded coverage.

When API monitoring can stop execution

Current developer documentation separates coverage from intervention. Covered tool-using Responses API requests can be stopped when persisted reasoning, WebSockets or OpenAI compaction preserve conversation continuity. Requests without those mechanisms can generate configured webhook alerts while continuing. Chat Completions requests fall outside this monitoring system.

Monitoring is asynchronous: blocking can follow completed actions without reversing them. Developer guidance calls for checking task state and tool records. The API offers no general mechanism to resume a stopped conversation.

ChatGPT and Codex offer review and, where available, continuation with monitoring active. Mobile or Zero Data Retention requests can lack explanations or resumption.

The API’s data-control documentation says submitted data is excluded from model training or improvement unless a customer explicitly opts in. Approved Zero Data Retention customers have content excluded from abuse-monitoring logs, subject to feature limits. Additional retention controls require prior OpenAI approval and can be selected at organization or project level.

Combining it with Private Safety Processing supports automated monitoring while preserving those protections. That configuration requires customer-controlled storage and must meet additional technical and operational conditions. For Responses requests with Zero Data Retention, the store parameter is treated as false even when set to true.

Alerts are configured per API project or supported ChatGPT-authenticated workspace. Workspace webhooks require an owner and are separate from personal-account settings. An admin or member role alone is insufficient.
