Opening the doors to METR is a meaningful signal: independent evaluations are quietly becoming the trust infrastructure of the frontier-lab era. The nonprofit has built real credibility through capability assessments for several major labs, so this is unlikely to be a rubber-stamp exercise. Still, an audit is only as good as its scope — the key question is whether METR's findings will be published in detail or compressed into a PR-friendly summary. In our view, labs that let external teams probe dangerous-capability safeguards before deployment raise the bar for the entire industry. Expect rivals to answer with their own audit partnerships; transparency is starting to look like a competitive feature rather than a compliance cost.
