How it works
Understand the calculation.
Input cost = input tokens ÷ 1,000,000 × input price per million tokens.
Output cost = output tokens ÷ 1,000,000 × output price per million tokens.
Total monthly API cost = (input cost + output cost) × workload multiplier.
Pricing presets were checked against official provider pricing pages on August 22, 2026. Cached tokens, batch discounts, long-context pricing, tools, search and regional charges may differ.
