API429 / Pricing research

FLUX API pricing: FLUX.2 Pro, BFL, fal and API429

FLUX.2 Pro uses megapixel-based pricing. This comparison covers text-to-image generation without input references; editing needs its own calculation.

A missing matching quote does not establish that the provider has no such model. Check the original source for the complete catalog and contract terms.

A megapixel is not the same as 2K

API429’s rate card treats 1024×1024 as 1 MP. A 2048×2048 image is 4 MP, not 2 MP. fal lists $0.03 for the first output MP and $0.015 for each extra input or output MP, rounded up. Without references, that is $0.045 for 2 MP and $0.075 for 4 MP.

Matching BFL, fal and gateway conditions

Black Forest Labs lists FLUX.2 Pro text-to-image from $0.03 and editing from $0.045. The BFL row compares only the base setting. A starting price does not establish the same cost at every resolution.

For e-commerce and advertising, also measure product fidelity, text, color and accepted-output rate. Several cheap retries can cost more than one usable generation. A pricing table is not a quality benchmark.
