YandexGPT Pro 5.1 pricing and specs

Input costs $9.4664 per 1M tokens (800 ₽) and output costs $9.4664 per 1M (800 ₽). Yandex AI Studio (Алиса) 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 $9.4664 for input and $9.4664 for output by 1,000. The same rates in rubles are 800 ₽ and 800 ₽ per 1M tokens. Both prompt tokens and completion tokens are billed.

The YandexGPT Pro 5.1 context window is 33K tokens (32,768). Everything shares that budget: the system prompt, the dialogue history, attached files and the answer the model writes. The figure comes from the Yandex AI Studio (Алиса) model card as of September 2026.

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 YandexGPT Pro 5.1 that gives 800 ₽ per 1M input tokens and 800 ₽ per 1M output tokens. When the rate moves, the ruble price moves with it.

YandexGPT Pro 5.1 belongs to the YandexGPT Pro family at Yandex AI Studio (Алиса). Models in the YandexGPT 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 YandexGPT model is listed on the provider page.
