GPT-4.1 mini pricing and specs

Input costs $0.4 per 1M tokens (33.8 ₽) and output costs $1.6 per 1M (135 ₽). 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 $0.4 for input and $1.6 for output by 1,000. The same rates in rubles are 33.8 ₽ and 135 ₽ per 1M tokens. Both prompt tokens and completion tokens are billed.

The GPT-4.1 mini context window is 1.0M tokens (1,047,576). 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 1.0M tokens (1,047,576) and a single response is capped at 33K 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 GPT-4.1 mini that gives 33.8 ₽ per 1M input tokens and 135 ₽ per 1M output tokens. When the rate moves, the ruble price moves with it.

GPT-4.1 mini belongs to the GPT mini family at OpenAI. Models in the ChatGPT 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 ChatGPT model is listed on the provider page.

The declared capabilities of GPT-4.1 mini are: tool calling, image input, structured output. It accepts text, images, PDF as input, and every attachment consumes tokens from the shared context window of 1.0M tokens. The list comes from the OpenAI model card and is refreshed with the catalog as of September 2026.
