Mistral: Mistral Medium 3.1

Mistral Medium 3.1 is a multimodal model from Mistral AI that accepts text, image, and file inputs and supports tool use. It offers a 131,072-token context window, which is sufficient for long documents or extended conversations. It does not include a built-in reasoning mode, and structured output support is unconfirmed, so users with strict JSON schema requirements should verify compatibility before committing. At $0.40 per million input tokens and $2.00 per million output tokens, this model sits in the budget-to-mid tier on price. Its blended benchmark score of 23.3 is drawn from only one independent benchmark, so treat that figure as preliminary rather than a well-validated signal. Teams that need multimodal input handling and tool support at a modest cost may find it worth evaluating, but buyers who prioritize verified performance across a broad benchmark suite should wait for wider coverage before drawing firm conclusions.
