Example: 1,000 requests with 1,000 input and 500 output tokens each would cost about $8.00 (1M input tokens × $2.00 + 0.5M output tokens × $12.00). Estimate your own usage.

Prices are the provider’s own per-token rates with zero markup, from our price list as of Oct 18, 2026. If a call has extra provider charges (images, audio, web search, cached prompts), you pay the reported cost.
