Patch Changes

  • #11922 d71c542 Thanks @richardscarrott! - feat(anthropic): declare mid-conversation support in model profiles. Claude Opus 4.8, Opus 5, Opus 5.5, Sonnet 5.5, Haiku 5.5, Fable 5 and 5.1, and Mythos 5 and 5.1 set midConversationSystemMessages and midConversationTools. Sonnet 5 sets system messages only.

    Regenerating the profiles from models.dev also adds Claude Opus 5.5, Sonnet 5.5 and Haiku 5.5, removes Claude Opus 4.1, and lowers Claude Sonnet 4.5's maxInputTokens to 200,000.
