Flux.1 Kontext [dev] Day-0 Support in ComfyUI
Generate. Edit. Repeat. All locally.
FLUX.1 Kontext [dev] just dropped and is natively supported in ComfyUI!
Developed by Black Forest Labs, Flux.1 Kontext [dev] is the open-source sibling of the FLUX.1 Kontext model. It’s a 12B parameter diffusion transformer model that understands and generates from existing images, under the FLUX.1 Non-Commercial License
Model Highlights
Same core capabilities as the FLUX.1 Kontext suite:
Character consistency: Preserve unique elements of an image, such as a reference character or object in a picture, across multiple scenes and environments.
Local editing: Make targeted modifications of specific elements in an image without affecting the rest.
Style Reference: Generate novel scenes while preserving unique styles from a reference image, directed by text prompts.
While the API version shipped previously provides the highest fidelity and speed, Flux.1 Kontext [dev] runs entirely on your machine, offering unmatched flexibility for developers, researchers, and power users looking to experiment.
