FLUX.2 Klein 4B: what one image costs
1 channel sells FLUX.2 Klein 4B. Each bills in its own unit — per token, per megapixel or per image — so every rate below is reduced to the same thing: one 1024×1024 image, with the conversion shown.

“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.
