Each logged request priced at the vendor’s list rates for its own token counts, including cache reads and any higher rate for long prompts. Average output: 698 tokens per request. Both models are priced on the requests up to 256K tokens that fit in both context windows; band shares above describe all requests.

What to watch for

They are built for different jobs: Codestral for autocomplete and quick edits, Devstral 2 for agent loops, so the cheaper one is not a drop-in swap. Both windows (256K and 262K) are smaller than about 12% of coding-agent requests. Devstral 2's price is Mistral's endpoint on OpenRouter, because Mistral's own price page does not list it.
