Billing

Is there any expiration date for my balance?

Your topped-up balance will not expire.

API Call

Are there any rate limits when calling your API? Can I increase the limits for my account?

The rate limit exposed on each account is adjusted dynamically according to our real-time traffic pressure and each account's short-term historical usage. We temporarily do not support increasing the dynamic rate limit exposed on any individual account. Thank you for your understanding.

Why do I feel that your API's speed is slower than the web service?

The web service uses streaming output, meaning each time the model outputs a token, it is displayed incrementally on the web page. By default, the API uses non-streaming output (i.e., stream=false), where the model's output is returned only after the complete generation. You can use streaming output in your API call to optimize interactivity.

Why are empty lines continuously returned when calling the API?

To prevent the TCP connection from being interrupted due to timeout, we continuously return empty lines (for non-streaming requests) or SSE keep-alive comments (e.g., : keep-alive for streaming requests) while waiting for the request to be scheduled. If you are parsing the HTTP response yourself, please ensure your parser handles these empty lines or comments appropriately.
