Service Pricing ​

Credit System Overview ​

OpenAI's official API billing is based on the number of tokens in each request and response. Each model has a different pricing structure, charged per 1,000 tokens consumed. 1,000 tokens is approximately 750 English words (or about 400 Chinese characters). OpenAI Model Pricing

To enable flexible billing, this platform uses a credit-based system. After topping up, your payment is converted to credits at a rate of 1 CNY = 10,000 credits.

After topping up, you can view credit consumption, obtain your API key, and check your balance in the dashboard.

● GPT-3 Pricing

GPT-3.5-turbo is officially priced by OpenAI at $0.002 per 1,000 tokens.

Converted to CNY at a 1/3.05 discount (based on a 7.1 exchange rate), the price is 0.004 CNY per 1,000 tokens — equivalent to 2 CNY per 1 USD.

● GPT-4 Pricing

Currently only the 8K context version is supported. Requests to GPT-4 default to 8K; gpt-4-32k is not supported at this time.

8K input pricing: $0.03 per 1K tokens

8K output pricing: $0.06 per 1K tokens

Due to the high cost of GPT-4, billing is at 1× the official price based on the current exchange rate (~7.1).

API Calls & Billing ​

The platform's token calculation algorithm is consistent with OpenAI's. When you call our API, the system calculates the cost in real time based on the model used and tokens consumed, and deducts it from your account. You can view a detailed credit consumption log at any time to verify the calculation. If you find any discrepancy with OpenAI's calculation, please contact us — if the error is on our end, we will compensate with credits.
