“billed” figures were measured by OpenRouter on 2026-09-11 and are reproduced here with attribution — their write-up. They are not our own measurements.
Rates are list prices as published by each channel on the date shown, and can change without notice. A channel that didn't respond on the latest sweep keeps its last verified row and date — it is never silently refreshed. Spreads only ever compare the same output size.
Comparing models too? The full image price board covers every image model we track, with seed and reference-image support per model.
