FLUX.2

Image Generation

Black Forest Labs' image generation and editing models, sold pay-as-you-go per image through the BFL API: FLUX.2 [max], [pro] and [flex], plus open-weight [klein] and [dev] models. BFL's newer FLUX 3 family is listed alongside them.

How It Works

You submit a text prompt, and optionally up to 10 reference images, via the API or the web Playground. A diffusion model repeatedly denoises a latent image toward the prompt while attending to the reference images to keep a character, style or product consistent, then outputs up to 4MP resolution. Billing is metered per output megapixel (plus per-megapixel reference-image cost) rather than per request, so a small draft costs less than a full-resolution render.

Plans and pricing

  • Per-image API pricing by variant (1st MP + additional MP): [max] $0.07+$0.03/MP
  • [pro] $0.03+$0.015/MP
  • [flex] $0.05/MP flat
  • [klein] 9B $0.015+$0.002/MP
  • [klein] 4B $0.014+$0.001/MP - reference images billed per MP too
  • [dev] is open-weights, sold separately via Open Weights Licensing plans or third-party hosts
