NoteThe claim asserts specific ASL classifications 'as of 2026-02' (February 2026), including Opus 4.6 launching in Feb 2026 under ASL-3. The source is dated May 22, 2025, and only discusses Claude Opus 4 (ASL-3) and Claude Sonnet 3.7 (ASL-2). The source does not mention: (1) Opus 4.5, (2) Opus 4.6, (3) Haiku's ASL level, or (4) any model releases or classifications after May 2025. The claim's 'as of 2026-02' date is ~9 months in the future relative to the source publication date, making the claim unverifiable against this source. The source cannot confirm or contradict future model releases and classifications that postdate its publication.

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.
