Mistral Medium 3.1 launched as the top MT-Bench tier on La Plateforme, alongside Mistral-tiny (efficiency) and Mistral-small (balance). At release Mistral Medium 3.1 scored 8.6 on MT-Bench. Mistral AI described it as a prototype endpoint undergoing deployed testing.
Mistral Medium 3.1's capability profile centers on five major European languages (English, French, Italian, German, and Spanish) alongside code generation. This multilingual design, combined with its position above tiny and small in the launch lineup, made it the default choice for many European-language workloads in Mistral AI's earliest days.
Mistral AI's portfolio has expanded since then, but Mistral Medium 3.1 remains available for teams with established integrations or workflows built around its specific capability profile.
