Frequently asked questions

How much does GPT 6 Luna cost?

GPT 6 Luna starts at $0.12 per 1M input tokens through the API Stock API. You pay per use from a single prepaid balance — there is no subscription — and the final price scales with parameters such as resolution or duration.

How do I get an API key for GPT 6 Luna?

Sign up for API Stock, top up your balance by any amount and create an API key in the dashboard — it takes a couple of minutes and needs no contract. The same key works with every model in the catalog, so there is no separate key to obtain for GPT 6 Luna.

How do I call the GPT 6 Luna API?

Send a POST request to https://api.api-stock.com/api/v1/chat/completions with your API key and the model "gpt-6-luna", using the openai-compatible request format shown in the quick start above.

What happens if a GPT 6 Luna request fails?

API Stock automatically retries the request on a reserve provider. If every provider fails, the charge is refunded to your balance.

Can I use GPT 6 Luna with the same API key as other models?

Yes. Every model on API Stock — video, image, music and chat — shares one API key and one prepaid balance, so you can switch to GPT 6 Luna without new credentials.
