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.
