Billing

Model API supports Token packages and pay-as-you-go. Both use the same API endpoint; billing is tied to the API key you create.

Comparison

	Token package	Pay-as-you-go
Payment	Prepay for a token quota	Deduct from account balance after use
Best for	Predictable monthly usage	Spiky or exploratory usage
Key type	Package key (bound to one package)	Pay-as-you-go key
Limits	Package remaining tokens + expiry	Optional daily/monthly CNY cap per key

Purchase in console Package subscription (one active purchase flow at a time).
Bind the package when creating an API key.
Each successful call reduces remaining tokens according to usage in the API response.
Check Package management and Usage stats in console.

Packages apply to models supported by that product — see console for model list and reference prices.

Top up account balance (CNY).
Create a key with pay-as-you-go billing.
Usage is priced per model; charges aggregate and deduct from balance (see Balance details in console).
Set daily/monthly spend cap on the key to avoid surprises (0 = no cap).

Billing is based on tokens (input + output), not “number of chats”. Token counts appear in API responses under usage.
