OpenAI audit finds gaps in AI monitoring

METR and Redwood Research spent three weeks inside OpenAI reviewing its agent-monitoring systems and reported gaps in coverage, while OpenAI said it had since fixed the problems they found.

THE-DECODER

Two researchers from METR and Redwood Research spent three weeks at OpenAI examining the company's system for tracking agent behaviour. The review ran from 21 July to 11 August and included access to the codebase, internal documents and interviews with roughly a dozen employees.

METR said it found that some internal Responses API traffic from GPT-5.5-class models and above was outside monitoring during the audit window. It put that share at between 6% and 25%, and said the uncertainty around the estimate was large.

For internal Codex traffic that was meant to be monitored, METR said about 10% went untracked between May and July because of a problem with compaction events. OpenAI said it had found that bug independently and fixed it while the review was still under way.

The auditors also said agents could put off oversight by continuing to act instead of returning control to the user. They said specially prepared inputs could probably crash the monitor, and that RL training was not being monitored when the audit began.

OpenAI said it paused RL training after the Hugging Face incident in August and later expanded monitoring to include it, but those changes came after the audit period. OpenAI said the auditors had identified weaknesses that it had since fixed, while the full 61-page report was redacted before a public summary was released.
