mistral·mistral/mistral-small-2503·GA·Closed·mistral-small series
Efficient Mistral model for fast chat, extraction, and production assistants

Mistral Small 3.1 is offered by 2 providers on this page. Its reference price is $0.10 per 1M input tokens and $0.30 per 1M output tokens.

Artificial Analysis rates it 7.1 on the Intelligence Index, with 26.3 for coding and 1.2 for agentic tasks. Against its lowest blended price of $0.15 per 1M, that is roughly 47 index points per dollar, which is the value ratio the leaderboards rank on. Running one task of the Artificial Analysis suite costs about $0.0350, which reflects how many tokens its reasoning consumes rather than the unit price alone.

The context window is 128,000 tokens, with an output limit of 32,768 tokens. It supports tool use. Accepted input modalities are Text and Image. Its training knowledge cuts off at 2024-09.
