Mistral coding agent model for repository tasks and software engineering workflows
Devstral Small by mistral is offered by 2 providers on this page. Its official list price is $0.10 per 1M input tokens and $0.30 per 1M output tokens.
Artificial Analysis rates it 8.7 on the Intelligence Index. Against its lowest blended price of $0.15 per 1M, that is roughly 58 index points per dollar, which is the value ratio the leaderboards rank on.
The context window is 128,000 tokens, with an output limit of 128,000 tokens. It supports tool use. The weights are open, so it can also be self-hosted or served through a gateway of your choice. Its training knowledge cuts off at 2025-05.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.

The same benchmark scores very differently across harness / dataset, so the qualifying conditions must be shown together.
Individual evaluations run by Artificial Analysis, on the same reasoning tier as the intelligence score above. Each benchmark has its own task set and harness, so rows are not comparable with one another. The Intelligence Index above draws on a different, newer set of evaluations.
