FLUX.2 pro 1920x1080 costs $0.045 on fal: the arithmetic

On fal, a 1920x1080 FLUX.2 pro image costs $0.045 and a 1024x1024 image costs $0.03. The rule is $0.03 for the first megapixel plus $0.015 for each extra megapixel, and 1920x1080 is about 2.07 MP, so it rounds up to 2 MP: $0.03 plus $0.015. Sume bills what its endpoint pricing lists, so print it before you budget.

Rule and examples are from fal's FLUX.2 pro page, read 2026-10-03.

The rule

The page states both examples. The rounding is explained for the edit endpoint as rounded up to the nearest megapixel, which is what the 1920x1080 example implies.

Whether Sume's row varies by size is not something this post verified. Compare usage.cost from one real call at each size.
