FLUX.1 Fill Dev LoRA API

FLUX.1 Fill Dev LoRA runs Black Forest Labs' FLUX.1 Fill [dev], a 12-billion-parameter model trained for inpainting, with up to three LoRA files trained for FLUX.1 dev. Send a source image and a black-and-white mask: only the white area is redrawn to match your prompt, the rest comes back untouched, and nothing is filtered.

Call it with the model name black-forest-labs/flux-1-fill-dev-lora/edit on POST /jobs/createTask, from 7 credits per image ($0.07). New accounts get 30 free credits to try it in the Playground first.
