Source details and check notes

Authors: Anthropic
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.

Archive copy: Open archived copy, captured 2024-06-20: Claude 3.5 Sonnet Model Card Addendum. No publication date is recorded for this source. An archive copy shows only what the archive retrieved on 2024-06-20. It does not prove what the page said earlier, and it can differ from the copy checked on 2026-11-04.

Reuse: No open redistribution licence asserted. Bibliographic metadata, editorial paraphrases and short attributed quotations (at most 50 words each). Recheck terms before wider redistribution.
Check notes: Candidate pack passage, model cards compared (research/model-cards-2). The quotation (25 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. A cross-family machine check (2026-11-04, item 6) checked this passage’s cell and agreed with the pack. No human editorial review.

Status and meaning

Relation. Publication of a specific document or version. Publication of a policy is not evidence of implementation.

Date. The addendum prints no date of its own, so no date of the card is recorded.
