o4-mini-deep-research pricing and specs

Input costs $2 per 1M tokens (169 ₽) and output costs $8 per 1M (676 ₽). OpenAI 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 $2 for input and $8 for output by 1,000. The same rates in rubles are 169 ₽ and 676 ₽ per 1M tokens. Both prompt tokens and completion tokens are billed.

The o4-mini-deep-research context window is 200K tokens (200,000). Everything shares that budget: the system prompt, the dialogue history, attached files and the answer the model writes. The figure comes from the OpenAI model card as of September 2026.

The context window is 200K tokens (200,000) and a single response is capped at 100K tokens, so longer output has to be generated in parts. Rate limits are set by OpenAI per account and depend on your plan rather than on the model, so they are not listed here.

Providers quote their tariffs in US dollars, so the ruble amounts here are a conversion at the official Bank of Russia rate of 84.51 ₽ per dollar. For o4-mini-deep-research that gives 169 ₽ per 1M input tokens and 676 ₽ per 1M output tokens. When the rate moves, the ruble price moves with it.
