Monthly cost projections
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 (84% read discount) |
|---|---|---|
| 1K | $12.5 | $11.03 |
| 10K | $125 | $110.3 |
| 100K | $1,250 | $1,103 |
| 500K | $6,250 | $5,515 |
| 1M | $12,500 | $11,030 |
Caching estimate assumes 70% of input tokens are cache reads. Your actual cache hit rate will depend on prompt structure and reuse.
