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 | $130 | $123.7 |
| 10K | $1,300 | $1,237 |
| 100K | $13,000 | $12,370 |
| 500K | $65,000 | $61,850 |
| 1M | $130,000 | $123,700 |
Caching estimate assumes 70% of input tokens are cache reads. Your actual cache hit rate will depend on prompt structure and reuse.
