METR's Embedded Pilot at OpenAI Published, but Redactions Scale and 2.5-Month Delay Unexplained

METR has published a brief write-up of its embedded assessment pilot: two employees from METR and Redwood Research spent three weeks on-site at OpenAI this summer, evaluating the systems OpenAI uses to monitor for misalignment from internal agents.

tomekkorbak, a former OpenAI employee who worked on this third-party engagement, voiced two criticisms: METR wasn't allowed to comment on the scale of OpenAI's redactions, and there is no explanation for why publication was delayed by 2.5 months — fresh first-hand evidence for transparency concerns around external audits.
