Claude 3 Haiku (Mar 2024)
Claude 3 Haiku (March 2024) is the dated, stable release of Anthropic's entry-level model in the original Claude 3 generation. The March 2024 snapshot provides a fixed behavioral baseline that teams can rely on for regression testing, consistent evaluations, or legacy integrations that were built before the 3.5 series launched.
It remains one of the fastest and most affordable Claude models for general text tasks. While superseded in capability by Claude 3.5 Haiku, the pinned 3 Haiku release is valuable wherever consistency with earlier outputs matters more than accessing the latest improvements.
