## Per-token billing

Serverless requests are billed per token, in USD per million tokens:

| Token type | Billed at |
|---|---|
| Input tokens | The model's input rate |
| Cached input tokens | The model's cached rate, when a prompt prefix is reused |
| Output tokens | The model's output rate |
| Reasoning tokens | The output rate |

The `usage` object in every response reports the tokens you were billed for.

## Credits

Self-serve accounts use prepaid credits: usage is deducted as requests complete. Requests are rejected with `402` when the
balance runs out. Credit expiry, refunds, and taxes are covered by the
[Billing, Credits & Refund Policy](/legal/billing).

## Enterprise invoicing

Enterprise customers can be invoiced monthly. [Contact sales](/contact).

## Dedicated endpoints

Dedicated endpoints are billed per GPU-hour rather than per token — see [Dedicated endpoints](/docs/dedicated/overview).
