Mercury 2 pricing and specs

Input costs $0.25 per 1M tokens (21.13 ₽) and output costs $0.75 per 1M (63.38 ₽). Inception 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 $0.25 for input and $0.75 for output by 1,000. The same rates in rubles are 21.13 ₽ and 63.38 ₽ per 1M tokens. Both prompt tokens and completion tokens are billed.

The Mercury 2 context window is 128K tokens (128,000). Everything shares that budget: the system prompt, the dialogue history, attached files and the answer the model writes. The figure comes from the Inception model card as of September 2026.

The context window is 128K tokens (128,000) and a single response is capped at 50K tokens, so longer output has to be generated in parts. Rate limits are set by Inception 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 Mercury 2 that gives 21.13 ₽ per 1M input tokens and 63.38 ₽ per 1M output tokens. When the rate moves, the ruble price moves with it.

Mercury 2 belongs to the Mercury family at Inception. Models in the Mercury 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 Mercury model is listed on the provider page.
