Mistral Medium 3

Mistral Medium 3 is an advanced AI model suited for demanding production workloads, developed by Mistral and released in May 2025.

Mistral Medium 3 was released on May 1, 2025 as a closed API-only model positioned between Mistral’s open-weight Small line and the commercial Large series. Medium 3 targets the latency-optimised, cost-sensitive API segment: use cases where the open-weight models feel limited but the full capability of Large 3 is unnecessary and its cost prohibitive. It is available through Mistral’s api.mistral.ai and has been adopted primarily for European enterprise applications that need a hosted solution rather than self-deployment.
