Anthropic — AI Safety Level: ASL-3 (Opus 4, Opus 4.5, Opus 4.6), ASL-2 (Sonnet, Haiku)

NoteThe claim asserts specific ASL classifications for models as of February 2026, including Opus 4.6 (launched Feb 2026 under ASL-3), Opus 4.5, and Opus 4 all at ASL-3, with Sonnet/Haiku at ASL-2. The source document is dated May 22, 2025, and only discusses Claude Opus 4 (ASL-3) and Claude Sonnet 3.7 (ASL-2). The source predates the claim's reference date (2026-02) by approximately 9 months and contains no information about Opus 4.5, Opus 4.6, or their ASL classifications. While the source confirms that Opus 4 is ASL-3 and Sonnet models are ASL-2 as of May 2025, it cannot verify the claim's assertions about models and classifications that allegedly exist in February 2026. This is a temporal mismatch: the source is from an earlier period and does not address future model releases.

NoteThe source text is dated May 22, 2025, and discusses the activation of ASL-3 for Claude Opus 4 only. The claim references February 2026 information (Opus 4.6 launch, current status of all models as of 2026-02), which is 9 months in the future relative to the source date. The source does not address Opus 4.5, Opus 4.6, or provide information about model classifications as of February 2026. While the source confirms Opus 4 is ASL-3 and implies Sonnet remains ASL-2, it cannot verify the specific claim about future model releases and their safety levels. This is a temporal mismatch issue—the claim makes assertions about a future date that the source cannot address.
