# Mistral Ministral 3B — deprecation status

> Yes — Ministral 3B is retired. Mistral deprecated it on December 2, 2025 and shut it down on December 31, 2025; API requests to it now fail. The recommended replacement is Ministral 3 3B.

The smaller half of les Ministraux, and the only one of the pair whose weights Mistral never released in any form - it was API-only for its entire fourteen months. When it shut down at the end of 2025 the model became genuinely unavailable rather than merely unhosted.
