# Mistral Magistral Medium 1.1 — deprecation status

> Yes — Magistral Medium 1.1 is retired. Mistral deprecated it on October 31, 2025 and shut it down on November 30, 2025; API requests to it now fail. The recommended replacement is Mistral Medium 3.5.

A July 2025 refresh that mostly cleaned up the reasoning traces and reduced the amount of language-switching mid-thought that plagued 1.0. It was deprecated three months later in the same October wave that took every other Magistral shipped that year, and had thirty days to live after the announcement.
