Billing & usage
Credits & billing
Fund a prepaid balance and pay published input, cached-input, and output rates for the models you call.
Credits
Open Billing / Credits to create a deposit invoice and follow the payment instructions. Credit is issued only after the payment callback is authenticated and the provider independently confirms the payment.
Your wallet shows available and reserved credit separately. Reserved credit is unavailable to new requests until the hold settles or is released.
Token prices
Each model has separate rates per one million input, cached-input, and output tokens. Cached input is part of total input and is not charged twice. A request keeps the price version captured when it starts.
| Amount | Meaning |
|---|---|
| Input | Uncached prompt/input tokens. |
| Cached input | The cached subset of prompt tokens. |
| Output | Generated completion tokens. |
| 1 USD | 1,000,000,000 integer nano-USD. |
Reservations and settlement
- A conservative maximum is reserved before inference.
- Trusted usage settles the final charge at the captured price.
- Unused reserved credit is released.
- Uncertain usage stays held for trusted reconciliation.
Verified input accounting allows smaller holds for short requests. Other live models reserve their full context allowance. Preview models use request-sized simulated holds. Final charges always use the reported token usage; estimates are never billed as actual usage.
Development and refunds
Development mock invoices and test credits have no monetary value. Live access is launch-gated. Refund handling follows the published policy and retained financial records.
