Mistral Medium 3

  • Mistral AI
  • Released May 7, 2025
  • No public weights listed
  • 131K context

Mistral Medium 3 costs $0.40 per million input tokens and $2.00 per million output tokens, as of October 21, 2026. None of the 6 coding benchmarks behind the index has measured it, so it has no coding index, but 57 benchmarks outside the index have a result below.

Mistral Medium 3's output price ranks 184 of 349 priced models, counting from the cheapest.

  • Coding index Not benchmarked No benchmark coverage

Benchmarks: 57 of 195 measured

The tick on a coding bar is the median of every model measured on it. Outside coding, the place is this model's rank on that board. A board that never ran the model says so.

What it costs

A list price says what a token costs. The cost per solved task says what a working answer costs, which is the number that decides.

Output price against the market

Mistral Medium 3 pricing
$0.05Dashed line: median $1.80, log scale$600.00
$2.00 per million output tokens is cheaper than 45% of the 344 paid models in the catalog.

Cost per solved task

How it is computed

Neither board that publishes what a SWE-bench Verified attempt costs, Vals AI and swebench.com, has run this model. We leave the number out rather than estimate it.

What the boards say about its runs

Beside a result, many boards publish what the run cost, how long it took, the tokens it spent or the votes behind a rating. Each figure as its board printed it, one board per row.
