Projected monthly spend at different call volumes, using code generation as a representative workload (2,000 input / 4,000 output tokens per call).
| Calls / month | Without caching | With caching (90% read discount) |
|---|---|---|
| 1K | $220 | $207.4 |
| 10K | $2,200 | $2,074 |
| 100K | $22,000 | $20,740 |

| 1M | $220,000 | $207,400 |
Caching estimate assumes 70% of input tokens are cache reads. Your actual cache hit rate will depend on prompt structure and reuse.
