Claim and evidence Close ×
Where the Frontier Safety Framework v1.0 set two Critical Capability Levels in a Biosecurity risk domain, one for enabling a non-expert and one for enabling an expert, v2.0 sets a single level, CBRN uplift 1, in a combined chemical, biological, radiological and nuclear risk domain. Copy claim link

Supporting evidence: primary · 2 sources
Reasoning and premises Premises: v1.0 states two Biosecurity Critical Capability Levels in the table on PDF p. 5, recorded as recorded separately; v2.0 states one CBRN level, recorded as recorded separately, in a domain it defines over all four CBRN letters (recorded separately). The v2.0 change notes list no entry for this difference, so the comparison is Selekoa’s, drawn from the two inspected tables alone.
Basis of the change Inferred by comparing the two editions. No publisher statement of this change is recorded. Subject version v2.0 · Published 2025-02-04 · Effective date not established Object version v1.0 · Published 2024-05-17 · Effective date not established Date 2025-02-04 · publication Scope and limits A comparison of the two inspected editions, not a publisher statement. The record does not say that any capability level was deleted, weakened or strengthened, and establishes no safety ranking.

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. Difference between the two editions, dated by the later edition’s publication date.
