# Mistral Small 3.0 — deprecation status

> Yes — Mistral Small 3.0 is retired. Mistral deprecated it on November 6, 2025 and shut it down on November 30, 2025; API requests to it now fail. The recommended replacement is Mistral Small 4.

The 24B rewrite that reset the Small line in January 2025, dropping the layer count for latency and landing at roughly Llama 3.3 70B quality at a third of the size. It was the model that made "small" mean 24B rather than 22B at Mistral, and it lasted ten months.
