Requests are load balanced across every provider serving this model, each offering its own rate, so what you pay is a blend rather than a single number. These are the blended rates actually paid — priced at what a provider offered, capped at list.
Measured over 7 windows: 1,259 requests and 2,303,433 input-side tokens. Most recent window closed 2026-08-11 02:24 UTC.
