Source details and check notes

Authors: Google DeepMind
Version: Frontier Safety Framework v3.1; publication date 2026-04-17.
Version date: 2026-04-17
Canonical address: Open the canonical source ↗
Accessed: 2026-09-18
Language: English (en)
Archive copy: Open archived copy, captured 2026-04-23: Frontier Safety Framework — v3.1. Captured 6 days after the recorded version date. An archive copy shows only what the archive retrieved on 2026-04-23. It does not prove what the page said earlier, and it can differ from the copy checked on 2026-09-18.
Attribution: Google DeepMind, Frontier Safety Framework — v3.1.
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 quotation (29 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 whose SHA-256 equals the pack’s. Matching ignored differences of whitespace, case, quotation marks, dashes and Unicode compatibility forms, so the source’s typography can differ. 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. 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. Provision as stated in this edition, dated by the edition’s publication date.
