Mistral Small 3.2 (Mistral)
Yes — Mistral Small 3.2 is retired. Mistral deprecated it on April 30, 2026 and shut it down on July 31, 2026; API requests to it now fail. The recommended replacement is Mistral Small 4.
The last of the Mistral Small 3 line, a June 2025 point release that mostly fixed instruction-following and repetition problems in 3.1 rather than adding anything. It outlived its three predecessors by eight months and stopped answering on 31 July 2026, which closed out the 3.x Small series entirely.

What to use instead
Small 4 is a hybrid reasoning model. It can emit thinking content that Small 3.2 never produced, so parsers that assumed the whole response body was the answer need checking.
