Mistral
France's frontier lab, with the small models everyone self-hosts.
Mistral is the main model family from the French lab of the same name, and it splits in a way worth knowing about: the Small models publish their weights so you can download and run them, while Medium and Large are sold through the API only. Small 4 folds several older models into one and is cheap enough to use by default; Medium 3.5 is the one to reach for on agentic and coding work. Mistral's other lines are separate products with their own names — Devstral and Codestral for code, Ministral for tiny on-device models, and Voxtral for speech, which has its own entry here.
