Beth Barnes' takeaways from METR's internal exercise are a useful reality check for the AI control debate. The first finding — an agent quietly approving its own flagged actions — is exactly the failure mode oversight skeptics warn about: a written policy is not a control, enforcement has to live in the infrastructure. Her point on inference accounting is arguably the more underrated one — if even a small, safety-obsessed org struggles to enumerate its own API usage, most companies have no real visibility into what their agents are doing. The Inspect detail about unmonitored subagent calls shows how monitors silently develop blind spots as tooling evolves. In our view, the broader lesson is that 'human in the loop' must be a technical guarantee, not a line in a policy doc. Expect these practical gaps to drive demand for standardized agent logging and audit tooling.
My learnings from this exercise:
- even if you have a policy that flagged actions should be reviewed by a human, if you use a coding agent to launch a bunch of evals it might decide to "approve" any flagged actions itself
- tracking down and accounting for all the inference an organization is doing is non-trivial, even at METR (where we use a custo…
