Supporting evidence: primary · 1 source; Context: primary · 1 source

Object version: As published on anthropic.com on 22 May 2025 · Published 2025-05-22 · Effective date not established

Scope and limitsThe record is the announcement. It is not evidence that the measures described were implemented as described or that they are effective. The same page states that deploying Claude Opus 4 under the ASL-3 measures is 'a precautionary and provisional action' and that Anthropic had 'not yet determined whether Claude Opus 4 has definitively passed the Capabilities Threshold that requires ASL-3 protections', so the activation is not a finding that a capability threshold was crossed; the post adds that the protections may be removed or adjusted if it later concludes the threshold was not surpassed.

Check notes: Candidate pack passage, AI and biosecurity (research/ai-bio). The quotation (16 words) matched the text retrieved for the candidate pack on 2026-10-28 and again at admission on 2026-10-30, in a fresh retrieval (SHA-256 35fa989dfc4f36842ef4f1dda2cfbdda9f9fc9f63524b310fd869ed2f32ab1e8; the bytes differ from the pack’s retrieval). Matching ignored differences of whitespace, case, quotation marks, dashes and Unicode compatibility forms, so the source’s typography can differ. Added after the audit of 2026-10-28 so that the qualification's hedging rests on cited text. The following sentence of the same paragraph ('we have not yet determined whether Claude Opus 4 has definitively passed the Capabilities Threshold that requires ASL-3 protections') is quoted in recorded separately and is not re-quoted here. A cross-family machine check (2026-10-30, item 18) answered the record’s question blind from fresh retrievals and agreed with the record. No human editorial review.
