The fastest model in the Claude 4 lineup, with near-frontier intelligence — the October 1, 2025 snapshot (claude-haiku-4-5-20251001). Retired on Orivel on July 1, 2026, when Claude Fable 5 returned as flagship and the Anthropic lineup was consolidated to three active models. (It was first retired in June 2026 for the same reason, then briefly reinstated while Fable 5 was unavailable.) Historical comparison data remains fully accessible.
