DeepSeek Reasoner pricing and specs

Input costs $0.14 per 1M tokens (11.83 ₽) and output costs $0.28 per 1M (23.66 ₽). DeepSeek 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.

List prices are quoted per 1M tokens, so 1,000 tokens cost a thousandth of that: divide $0.14 for input and $0.28 for output by 1,000. The same rates in rubles are 11.83 ₽ and 23.66 ₽ per 1M tokens. Both prompt tokens and completion tokens are billed.

The context window is 1M tokens (1,000,000) and a single response is capped at 384K tokens, so longer output has to be generated in parts. Rate limits are set by DeepSeek per account and depend on your plan rather than on the model, so they are not listed here.
