Our take
Written Aug 3, 2026Mistral Medium 3 is a hosted-only text-and-image model from Mistral AI that can handle up to 131,072 tokens in a single request. It sits between the company's free tier and its top-tier offerings, with two tracked providers at identical rates.
Pick this for generalist tasks needing a 128-thousand-token request limit on a proprietary API, or when you prefer Mistral's own hosting with its measured 43 tokens per second throughput. Skip it if you need verified benchmark scores, a choice of cheaper providers, or the ability to download and run the model yourself.
The case for it
- 131,072-token request limit — among the larger windows in Mistral's lineup, suited to long-document work.
- Accepts text, images and files, making it a multimodal generalist rather than text-only.
The case against it
- No benchmark scores in our data, so there is no measured quality or speed advantage over peers at this tier.
- Parameter count and architecture undisclosed by the vendor.
- Only two tracked offers at identical pricing, with no cheaper alternative.
How good is it?
We hold no score for this model.
We look for every model we track on every board we watch, and none of them has turned up Mistral Medium 3 — so there is no intelligence, coding, agentic or writing score to show you, not a low one, none.
Or rent it from someone else
Why this differs from the header. The strip above quotes Mistral AI's own list price. This is the cheapest live offer at the widest standard context we hold, whoever is serving it — a reseller undercutting a lab is ordinary commerce, not an error.
