How much does GPT-6 Astra cost per token?

GPT-6 Astra costs $10.00 per million input tokens and $50.00 per million output tokens through the OpenAI API. That is $0.00001 per input token and $0.00005 per output token.

How much does a typical GPT-6 Astra request cost?

A request with 1,000 input tokens and 500 output tokens costs about $0.035 on GPT-6 Astra, or $35.00 per thousand requests.

What is the context window of GPT-6 Astra?

About GPT-6 Astra pricing

GPT-6 Astra is OpenAI’s top-tier model, aimed at the hardest reasoning, coding and agentic work. It is billed per token: $10.00 for every million tokens you send and $50.00 for every million tokens it generates, so output costs 5× as much as input.

For a typical request of 1,000 input and 500 output tokens, GPT-6 Astra costs about $0.035 — the 13th-cheapest of the 14 models we track. One million input tokens is roughly 2,000 pages of English prose.

With OpenAI’s batch API (50% off, results within 24 hours) the rate drops to $5.00 input and $25.00 output per million tokens.
