Frequently asked questions
How much does the GPT-6 Astra API cost?
Input costs $10 per 1M tokens (845 ₽) and output costs $50 per 1M (4,225 ₽). 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.
How much do 1,000 GPT-6 Astra tokens cost?
List prices are quoted per 1M tokens, so 1,000 tokens cost a thousandth of that: divide $10 for input and $50 for output by 1,000. The same rates in rubles are 845 ₽ and 4,225 ₽ per 1M tokens. Both prompt tokens and completion tokens are billed.
How many tokens does GPT-6 Astra hold?
The GPT-6 Astra context window is 1.1M tokens (1,050,000). 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.
What are the GPT-6 Astra limits?
The context window is 1.1M tokens (1,050,000) and a single response is capped at 128K 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.
How is the GPT-6 Astra price in rubles calculated?
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-6 Astra that gives 845 ₽ per 1M input tokens and 4,225 ₽ per 1M output tokens. When the rate moves, the ruble price moves with it.
Can GPT-6 Astra reason?
Yes, GPT-6 Astra declares a reasoning mode: it works through intermediate steps before it answers. Those steps add output tokens, so a call with a long reasoning chain costs more and takes longer than a plain completion. Capabilities declared for the model: reasoning, tool calling, image input, structured output.
What capabilities does GPT-6 Astra support?
The declared capabilities of GPT-6 Astra are: reasoning, tool calling, image input, structured output. It accepts text, images, PDF as input, and every attachment consumes tokens from the shared context window of 1.1M tokens. The list comes from the OpenAI model card and is refreshed with the catalog as of September 2026.
