- Input: 500 tokens
- Output: 400 tokens
- Total: 900 tokens ≈ 0.9K tokens
- Credits consumed: 0.9 * 0.16 = 0.144 credits
- Actual charge (rounded up): 0.15 credits
Important Notes
- The system automatically checks if your account balance is sufficient to cover the estimated credit consumption before using any model
- Actual credit consumption is calculated based on the final total of input and output tokens
- We recommend estimating potential token usage before use to ensure your account has sufficient credits
