2. Credit System

All platform model services use credits for pay-as-you-go billing. If your subscription doesn't include enough credits or you need more, you can purchase additional credits on our Purchase page. Credit pricing varies by plan, ranging from 1 credit = $0.0016 to $0.0019.

You can also earn free credits through our Rewards Program.

Credit pricing for different models is as follows:

Text Conversation

Note: Most text-based API calls are calculated by tokens, consistent with OpenAI's token calculation standard. Generally, 1000 tokens equals approximately 500 Chinese characters or 750 English words. You can simulate token counts using OpenAI's token calculator.

Token calculation for a conversation includes both request and response tokens. The request includes agent settings, conversation history, knowledge base content, and user query. You can view these details in the usage records on the My Account page. For information on token length limits configuration, please refer to the corresponding section in Agent Management.

Usage less than 1 credit will be rounded up to 1 credit.
