Scope and limitsThe addendum states autonomy evaluations (software-engineering tasks) and the shared outcome. It also states that METR explored the model's autonomy-relevant capabilities, without giving METR's result. What the card states, quoted from the expression read. A card is the developer’s own account: not evidence that an evaluation was run as described, that a safeguard works, or that a finding is independent.

Version: Retrieved for the candidate pack on 2026-11-04 (SHA-256 ac396c7f155dcbfb33ceb342b48647e330ca518c01c7f508001d6aad93257a03) directly from the publisher’s host. Retrieved again on 2026-11-03 with the same SHA-256. The addendum prints no date. Anthropic's card index gives June 2024, and an update line of the Claude 3 card dates the addendum's addition to that card to June 20, 2024; neither is the addendum's own date. The archive capture was found by an index search of the Internet Archive on 2026-11-03; it was not opened, and its bytes are not authenticated.

Check notes: Candidate pack passage, model cards compared (research/model-cards-2). The quotation (18 words) matched the card’s text retrieved for the candidate pack on 2026-11-04 (SHA-256 ac396c7f155dcbfb33ceb342b48647e330ca518c01c7f508001d6aad93257a03) and again on 2026-11-04, after the adjudication, in a fresh retrieval with the same SHA-256. Matching ignored differences of whitespace, case, quotation marks, dashes, PDF line-break hyphens and Unicode compatibility forms, so the source’s typography can differ. No human editorial review.

Status and meaning

Editorial status. Machine-checked. Machines found this record and checked it against its sources; no person accepted it individually. Each evidence record above shows how it was checked.

Relation. An exact framework edition, or another document with an exact expression, states one provision: a capability threshold or risk level and its trigger, a required safeguard or action, a decision authority (who decides, recommends, can overrule or is informed), a stated exception, or another statement of its content, such as a licence term or a prospectus statement. The passage records what the document says, not implementation, compliance or effectiveness. Provisions with the same key align across editions of one family.

Date. The card prints no date of its own, so its cells carry no date.
