Legacy model retained for compatibility with older integrations
Devstral Small 2505 by mistral is offered by 3 providers on this page. Its official list price is $0.10 per 1M input tokens and $0.30 per 1M output tokens. The lowest paid channel is NanoGPT at $0.06 / $0.06 per 1M, about 2.0× below the list price. That channel is a third-party gateway, so confirm its availability and rate limits before depending on it.
The context window is 128,000 tokens at the reference host, but hosts report different limits, from 32,768 to 128,000, so the usable window depends on the provider you pick. It supports tool use. The weights are open, so it can also be self-hosted or served through a gateway of your choice. Providers report the capability flags inconsistently, so verify a specific feature against the host you plan to use. Its training knowledge cuts off at 2025-05.
Sorted by blended price (input×0.75 + output×0.25) asc. The official channel always shows regardless of rank. Whether a gateway's low price is actually usable can't be verified.
