Market position
On blended price ($0.465 per 1M tokens at 30% input, 70% output) it is cheaper than 43% of models in the Budget price tier: 83rd cheapest of 160, tied with 8 others. Across every price tier it is cheaper than 70% of priced text models in the catalogue: 83rd cheapest of 303, tied with 8 others. No Arena score has been published for Mistral Small 4, so this page does not rank it on quality and OptimNow's quality bars do not apply to it. 77 of the 160 models we list in the Budget price tier carry one. An unranked model is unmeasured, not poor: the benchmark needs votes, and a recent release has not had time to collect them.
Licence, size and capabilities
Mistral Small 4 is open source: its weights are published under Apache 2.0, an OSI-approved licence with no field-of-use limit, so it can be self-hosted as well as bought by the token. Its published size is 119B parameters. Listed capabilities: Text, Vision, Reasoning, Agents. Filling its 262K context window once costs $0.0393 in input tokens at list price.
Pricing by host
A host is a company that runs the model and sells it by the token: the model maker, a cloud platform like Amazon Bedrock, Azure or Vertex, or an independent host. One model, several hosts, and often several prices. This model is sold by 1 host. The price we quote elsewhere on this page is marked. We quote one host's rate so that models stay comparable; it is not a recommendation to buy there.
Mistral is the only host with a published rate, $0.15 input / $0.60 output per 1M tokens, which is the price we quote.
| Host | Input $/1M | Output $/1M |
|---|---|---|
| Mistral (model maker, price we quote) | $0.15 | $0.60 |
