Source evidence

NoteThe source confirms title (Claude Sonnet 4.6), developer (Anthropic), release date (Feb 17, 2026), input price ($3), output price ($15), and context window (1M tokens = 1,000,000 tokens, not 200,000 as claimed). The context window claim is contradicted: the source explicitly states '1M token context window in beta' and 'Sonnet 4.6's 1M token context window', which is 1,000,000 tokens, not 200,000. The safety level 'ASL-3' is unverifiable—the source describes safety qualitatively but does not assign an ASL rating. The record's context window value is factually incorrect based on the source.
