Mistral Medium 3.1

by Mistral

Mistral Medium 3.1 is Mistral's frontier-class multimodal model, released August 2025 to lead professional use cases including coding, document understanding, and agentic workflows. It supports text, vision, function calling, and structured outputs across a 128k token context window. The model balances performance with efficiency, making it suitable for production systems that reason over documents and mixed-modality input. Support for agent orchestration and structured outputs makes it a versatile choice for full-stack AI applications. The model is scheduled for deprecation on May 22, 2026, with Mistral Medium 3.5 as its successor.
