Site calculation: estimated monthly cost at default usage
Site calculation, not a vendor quote. Assumptions: 100 calls/day · 2000 input / 800 output tokens per call · 30-day month · 30% cache hit rate. Same formula as the cost calculator.
| Effective input price | 30% × ¥0.27 (cache hit) + 70% × ¥1.35 (standard) = 1.03 CNY/1M tokens |
|---|---|
| Input cost | 100 × 30 × (2000 ÷ 1,000,000) × 1.03 = ¥6.16 |
| Output cost | 100 × 30 × (800 ÷ 1,000,000) × ¥8.1 = ¥19.44 |
| Estimated monthly cost | ¥25.60 |
