Overview
What Claude Haiku 3 is good at
This model is retired and no longer available. Anthropic retired claude-3-haiku-20240307 on 20 April 2026. Anthropic's own recommended replacement is Claude Haiku 4.5, and that is where this page points.
This page is kept deliberately rather than removed. Search demand for a model does not stop when its successor ships — people still look up Claude Haiku 3's pricing and limits long afterwards — and a 404 answers nobody. The pricing and specification figures that were published for this model are no longer maintained here, because a retired model cannot be bought and a stale number is worse than none. For current figures, follow the link to Claude Haiku 4.5.
