Frequently asked questions
How much does the Kimi K3.1 Pro API cost?
Input costs $2 per 1M tokens (161 ₽) and output costs $10 per 1M (805 ₽). Moonshot AI 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 80.54 ₽ per dollar for October 2026.
How much do 1,000 Kimi K3.1 Pro tokens cost?
List prices are quoted per 1M tokens, so 1,000 tokens cost a thousandth of that: divide $2 for input and $10 for output by 1,000. The same rates in rubles are 161 ₽ and 805 ₽ per 1M tokens. Both prompt tokens and completion tokens are billed.
How many tokens does Kimi K3.1 Pro hold?
The Kimi K3.1 Pro context window is 1.0M tokens (1,048,576). Everything shares that budget: the system prompt, the dialogue history, attached files and the answer the model writes. The figure comes from the Moonshot AI model card as of October 2026.
What are the Kimi K3.1 Pro limits?
The context window is 1.0M tokens (1,048,576) and a single response is capped at 1.0M tokens, so longer output has to be generated in parts. Rate limits are set by Moonshot AI per account and depend on your plan rather than on the model, so they are not listed here.
How is the Kimi K3.1 Pro price in rubles calculated?
Providers quote their tariffs in US dollars, so the ruble amounts here are a conversion at the official Bank of Russia rate of 80.54 ₽ per dollar. For Kimi K3.1 Pro that gives 161 ₽ per 1M input tokens and 805 ₽ per 1M output tokens. When the rate moves, the ruble price moves with it.
How is Kimi K3.1 Pro different from other Kimi models?
Kimi K3.1 Pro belongs to the Kimi K3 family at Moonshot AI. Models in the Kimi line differ in context size, price per 1M tokens and supported capabilities, so compare them by the numbers on their cards rather than by the name. Every Kimi model is listed on the provider page.
Can Kimi K3.1 Pro reason?
Yes, Kimi K3.1 Pro declares a reasoning mode: it works through intermediate steps before it answers. Those steps add output tokens, so a call with a long reasoning chain costs more and takes longer than a plain completion. Capabilities declared for the model: reasoning, tool calling, image input, structured output.
What capabilities does Kimi K3.1 Pro support?
The declared capabilities of Kimi K3.1 Pro are: reasoning, tool calling, image input, structured output. It accepts text, images, video as input, and every attachment consumes tokens from the shared context window of 1.0M tokens.
