Credits per 1M tokens by model

Chat models are billed per token — input (the messages you send) and output (the reply, including reasoning) at separate rates. Credits are reserved when the request starts and settled to the actual usage when it ends; a decimal credit is charged exactly, so a short request costs a fraction of a credit.

Credits per 1M tokens; every message in the request is input, the reply (including reasoning) is output. Money figures use the best-value pack ($0.013 per credit). Nothing is charged when no tokens were produced.

How to pay

Packs are prepaid: the balance is shared by every model and does not expire. Payment methods available right now:

  • Bank card or СБП (Faster Payments) in roubles — the receipt is sent to your email.
  • Cryptocurrency — USDT and other supported coins — through a hosted invoice; credits are added once the network confirms the transfer.
Can I pay with a Russian bank card or СБП?
Yes. Choose a pack, pick card or СБП at checkout and pay in roubles at the price shown on this page. Credits are added as soon as the payment is confirmed, usually within seconds, and the receipt goes to your email.
Can I pay with crypto (USDT)?
Yes. Choose a pack and pay the invoice in USDT or another supported coin. Credits are added automatically after the network confirms the transfer, usually within a few minutes.
Are unused credits refundable?
Unused credits are refunded on request to the original payment method within 10 working days. Credits spent on successful generations are not refundable; failed jobs are refunded to the balance automatically.

Billing

How credits are spent on images and on tokens.

How is a chat request billed?
Per token, at the model's input and output rates in credits per 1M tokens. Every message you send — system, user and earlier assistant turns — counts as input; the reply counts as output. Worked example: on a model priced at 20 credits per 1M input and 40 per 1M output, a request with 2,000 prompt tokens and a 500-token reply costs 2,000 ÷ 1,000,000 × 20 + 500 ÷ 1,000,000 × 40 = 0.04 + 0.02 = 0.06 credits. The usage block of every response shows the token counts and the cost.
Can a request cost a fraction of a credit?
Yes. Token-billed requests are charged in decimal credits with up to three decimal places, so a short chat request costs a few thousandths of a credit rather than being rounded up to one. Image generations stay whole credits per image. Your balance and the ledger show the exact figures.
What am I charged when a chat request fails or I abort a stream?
Nothing when no tokens were produced: a rejected request, a temporarily unavailable model or an upstream failure refunds the reservation in full. Credits are reserved for the estimated prompt plus the reply cap and settled to the actual usage once the call ends. If you close a stream early you pay only for the tokens generated up to that point.
Do thinking (reasoning) tokens cost extra?
They are billed as output tokens at the model's output rate — nothing more. When you enable thinking on a model that supports it, the reasoning text arrives alongside the answer and its tokens appear in completion_tokens; they also count toward max_tokens, so set it high enough for the task.
