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 (50% read discount)
1K$2.7$2.59
10K$27$25.95
100K$270$259.5
500K$1,350$1,297.5
1M$2,700$2,595

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