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 / monthWithout cachingWith caching (90% read discount)
1K$19.5$18.56
10K$195$185.55
100K$1,950$1,855.5
500K$9,750$9,277.5
1M$19,500$18,555

Caching estimate assumes 70% of input tokens are cache reads. Your actual cache hit rate will depend on prompt structure and reuse.
