Source details and check notes

Authors: Anthropic
Version: Responsible Scaling Policy v3.3; effective date 2026-05-26.
Version date: 2026-05-26
Canonical address: Open the canonical source ↗
Accessed: 2026-09-18
Language: English (en)
Archive copy: Open archived copy, captured 2026-05-28: Responsible Scaling Policy — v3.3. Captured 2 days after the recorded version date. An archive copy shows only what the archive retrieved on 2026-05-28. It does not prove what the page said earlier, and it can differ from the copy checked on 2026-09-18.
Attribution: Anthropic, Responsible Scaling Policy — v3.3.
Reuse: No open redistribution licence asserted. Selekoa practice: metadata, attributed paraphrases and short attributed quotations under the editorial policy (at most 50 words each; at most 400 quoted words per document across the dataset, and about 10% of a document under about 2,000 words). Documents are linked externally, not redistributed. Publisher terms that forbid quotation override this practice.
Check notes: Candidate pack passage, AI and biosecurity (research/ai-bio). The paraphrase is Selekoa’s, written from the text retrieved for the candidate pack on 2026-10-28; it is not a quotation and was not machine-matched. Paraphrased, not quoted: the text layer of this PDF displaces the first character of many lines, so a verbatim match cannot be checked mechanically against it. A cross-family machine check (2026-10-30, item 13) re-read the record’s sources and found full support. No human editorial review.

Status and meaning

Editorial status. Not reviewed by an editor. An exploratory record that no editor has accepted. This status does not say whether a person has read any linked passage. Each evidence record above shows how it was checked.

Relation. One scoped difference between document versions. The claim identifies publisher-stated change, official changelog/redline, or an explicitly inferred comparison. It does not establish implementation, effectiveness or a safety ranking.

Date. Change as stated in the v3.3 change log, dated by the edition’s effective date.
