Magistral Small 1.1

Magistral Small 1.1 updates the behavior and response format of Small 1.0. It retains the 24B Mistral Small 3.1 foundation and Apache 2.0 weights.

A revised reasoning format

Dedicated THINK tokens separate reasoning content from the final response. The reasoning instruction moves into the system prompt. The card also reports better Markdown and LaTeX formatting, shorter answers to easy prompts and fewer endless generations.Magistral Small 1.1 official model card

Similar capability, different behavior

Mistral describes overall benchmark performance as roughly similar to Small 1.0. The revision is useful when output parsing and generation behavior matter. Its weight card still warns about degradation beyond 40K despite describing a 128K architecture window.Magistral Small 1.1 official model card
