Magistral Medium 1.2

Magistral Medium 1.2 is Mistral's September 2025 update to its frontier-class reasoning model, combining advanced step-by-step reasoning with vision. The 1.2 release adds image understanding and reports notable gains on math and coding benchmarks over the original June 2025 Magistral. The model is built for transparent, interpretable reasoning across multiple steps and professional domains such as legal research, financial analysis, and software development. Its multi-step chains of thought are designed to be traceable, which suits high-stakes decision-making and complex problem solving. With a 128k token context window and multilingual reasoning across languages including English, French, Spanish, German, Italian, Arabic, Russian, and Simplified Chinese, Magistral Medium 1.2 pairs visual analysis with structured logical thinking.
