Mistral Large 3

by Mistral

Mistral Large 3 is a frontier-class, open-weight model built on a granular mixture-of-experts architecture with 41 billion active and 675 billion total parameters, released December 2025 under the Apache 2.0 license. It supports native function calling and tool use, making it well suited to reasoning-heavy and agentic workflows. The model excels at production-grade assistants, retrieval-augmented systems, long document understanding, and complex enterprise tasks. It pairs frontier capability with the flexibility of open weights for self-hosted deployment.
