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 (90% read discount) |
|---|---|---|
| 1K | $88 | $82.96 |
| 10K | $880 | $829.6 |
| 100K | $8,800 | $8,296 |
| 500K | $44,000 | $41,480 |
| 1M | $88,000 | $82,960 |
Caching estimate assumes 70% of input tokens are cache reads. Your actual cache hit rate will depend on prompt structure and reuse.
