Overview
Magistral Medium 1.2 is Mistral's proprietary reasoning model, producing explicit multilingual chains of thought and strong performance on math and structured problem-solving, now with a vision encoder for reasoning over images. It is competitive on reasoning benchmarks and notably good at showing its work in the user's language, but its agentic coding reliability remains below the closed frontier. Best used for math, logic, and analysis rather than autonomous engineering.
Strengths
- Dedicated, transparent reasoning traces
- Strong competition-math performance (AIME)
- Multimodal reasoning over text and images
- Function calling and JSON mode support
Trade-offs
- Slower and pricier per task (long thinking output)
- Closed weights (Magistral Small is the open variant)
- Agentic coding below the frontier
- Narrower general knowledge than flagships
Fit
Best for
- Complex math and scientific reasoning
- Multistep logic and analysis
- Visual reasoning tasks
- Auditable chain-of-thought workflows
Not ideal for
- Latency-sensitive or high-volume chat
- Long autonomous coding agents
Capabilities
Normalized 0—100
Ten axes, normalized 0–100 and scored the same way across the whole catalog — so a 78 here means what a 78 means anywhere else on the bench.
