FLUX.1 Fill [dev]

FLUX.1 Fill [dev] brings professional-quality inpainting to open development. Paint over any part of an image, describe what you want to see instead, and get natural results that respect the original context.

This is the same technology that powers Fill [pro], optimized for developers building creative tools. The model weights and code are available on Hugging Face under the Flux Dev License.

This model supports input image sizes up to 2048x2048; to select, set megapixels input to match_input. Larger generations will take a longer time.
