Uptime & Health
No uptime data yet

These providers haven't been health-probed for this model yet. The router still routes around upstreams that fail live requests — uptime fills in once probe history accrues.

About

Mistral Small 4 is a hybrid instruct-and-reasoning mixture-of-experts model on a 256k context window. Apache 2.0, and it takes image input as well as text. It folds Mistral's separate Instruct, reasoning and coding lines into one model, at $0.15 per 1M input and $0.60 per 1M output — roughly a tenth of Mistral Medium 3.5.
