How we price
Order
Providers are listed cheapest input rate first, then by output rate, a tie going to the creator's own listing. A provider that lists the model without a published rate sits at the end.
Prices
Base-tier, on-demand rates in USD per 1M tokens, converted at ECB reference rates where a provider publishes in another currency. Cached-input and batch rates show only where a provider publishes them. "Cheapest" marks the one provider with the lowest input and output pair; a tie wears no badge.
Cost
Input rate times the input tokens plus output rate times the output tokens, at the monthly volume set above the table. Cached-input, batch, long-context and reasoning-token billing are not modelled.

Common questions
What is GPT-6 Astra good for?
Long, end-to-end agent work: computer use, software engineering, professional tasks and science, with OpenAI's full hosted tool set. Reasoning effort is adjustable from low up to a max setting.
When is GPT-6 Astra not a good fit?
Budget-sensitive or high-volume traffic: it is the top of OpenAI's price range, where GPT-6 Sol and Luna are the lower-cost tiers. No audio or video input, and closed weights, so no self-hosting.
What is the cheapest way to run GPT-6 Astra?
The cheapest hosted rate is $10.00 / $50.00 per 1M tokens via OpenAI.
How does GPT-6 Astra compare with GPT-5.6 Sol?
Same 1M-token context and text and image input. GPT-6 Astra lists at 150% more per 1M input tokens and 150% more per 1M output tokens than GPT-5.6 Sol. It came out 2 months later and has a newer knowledge cutoff (April 2026 against February 2026).
Can I self-host GPT-6 Astra?
No. OpenAI does not publish the weights; GPT-6 Astra is available only through hosted APIs.
