Embedded evaluators
Plain English. Embedded evaluators are outside reviewers who sit inside a frontier lab with what Dario Amodei's pacing essay calls "employee-like access": desks, badges, laptops and the same tool permissions as internal risk teams, plus a contract that lets them publish findings the lab cannot edit. The lab keeps narrow redaction rights for security and commercial secrets, but cannot redact a finding for being unfavourable. METR is the named example.
Why it moves money. This is the one step in the pacing plan a lab can take alone, and the only one that costs something verifiable, so it is the credential a company about to list can show public investors. It is also a fixed compliance overhead that scales sub-linearly with revenue: cheap at a US$65bn run-rate, prohibitive for a new entrant. Critics from Cohere to D.A. Davidson read it as a barrier priced as a virtue, and note that the pool of "independent" evaluators is small and funded by the labs it would audit.
What to watch. Whether a review team is actually seated, who staffs it, and whether its first published report contains anything the lab would rather it did not. Departures of lab safety leads to the evaluator, as happened this week, test independence in both directions.
From the signals. Amodei calls for a paced frontier and hands outsiders the keys. Two counter-proposals that would actually cost Anthropic something. The slowdown case reaches Washington and prime-time TV.
