> Yes — Mixtral 8x7B is retired. Mistral deprecated it on November 30, 2024 and shut it down on March 30, 2025; API requests to it now fail. The recommended replacement is Mistral Small 4.

The first sparse mixture-of-experts anyone could download, dropped in December 2023 with no announcement, and the model that made MoE a mainstream open-weights architecture rather than a lab curiosity. Its API id was retired in March 2025; its influence on everything Mistral ships now was not.
