Overview

Mistral Large 3 is a general-purpose granular mixture-of-experts model with 675B total and 41B active parameters, post-trained for chat, agentic and instruction-following work. Mistral designs it for production assistants, retrieval-augmented systems and enterprise workflows, with native function calling, strong system-prompt adherence, a 256K context window and support for dozens of languages.

Strengths

  • Native function calling and JSON output
  • 256K context window
  • Dozens of supported languages

Use cases

  • Retrieval-augmented assistants over long documents
  • Enterprise knowledge work and agents
  • General coding assistance

Good to know

The weights include a vision encoder, but image input is not honoured on this alias, so treat it as text-only.
