Cost per thousand requests is a practical bridge between engineering metrics and business forecasting. It makes it easy to estimate a 10K, 100K or 1M request month without rebuilding a spreadsheet.
The math
Actual invoices can differ because providers may apply long-context pricing, caching rules, batch rates, tool-call fees, regional processing, negotiated contracts, taxes, or future pricing changes. Treat the output as a planning estimate.
Pricing sources
Current model rates are sourced from official provider pricing pages and verified on August 28, 2026. The methodology page records the source links and known limitations.
