Frequently asked questions
How much does the Gemini 3.1 Pro Preview API cost?
Input costs $2 per 1M tokens (169 ₽) and output costs $12 per 1M (1,014 ₽). Google 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 Gemini 3.1 Pro Preview tokens cost?
List prices are quoted per 1M tokens, so 1,000 tokens cost a thousandth of that: divide $2 for input and $12 for output by 1,000. The same rates in rubles are 169 ₽ and 1,014 ₽ per 1M tokens. Both prompt tokens and completion tokens are billed.
How many tokens does Gemini 3.1 Pro Preview hold?

What are the Gemini 3.1 Pro Preview limits?
The context window is 1.0M tokens (1,048,576) and a single response is capped at 66K tokens, so longer output has to be generated in parts. Rate limits are set by Google per account and depend on your plan rather than on the model, so they are not listed here.
