Frequently asked questions
How much does the Devstral Small API cost?
Input costs $0.1 per 1M tokens (8.45 ₽) and output costs $0.3 per 1M (25.35 ₽). Mistral bills the prompt and the completion separately, so the price of a call depends on how long both are. Ruble figures use the Bank of Russia rate of 84.51 ₽ per dollar for September 2026.
How much do 1,000 Devstral Small tokens cost?
List prices are quoted per 1M tokens, so 1,000 tokens cost a thousandth of that: divide $0.1 for input and $0.3 for output by 1,000. The same rates in rubles are 8.45 ₽ and 25.35 ₽ per 1M tokens. Both prompt tokens and completion tokens are billed.
How many tokens does Devstral Small hold?
The Devstral Small context window is 128K tokens (128,000). Everything shares that budget: the system prompt, the dialogue history, attached files and the answer the model writes. The figure comes from the Mistral model card as of September 2026.
What are the Devstral Small limits?
The context window is 128K tokens (128,000) and a single response is capped at 128K tokens, so longer output has to be generated in parts. Rate limits are set by Mistral per account and depend on your plan rather than on the model, so they are not listed here.
How is the Devstral Small price in rubles calculated?

What capabilities does Devstral Small support?
The declared capabilities of Devstral Small are: tool calling. It accepts text as input, and every attachment consumes tokens from the shared context window of 128K tokens. The list comes from the Mistral model card and is refreshed with the catalog as of September 2026.
Does Devstral Small have open weights?
