Readme

FLUX.1 Redux [dev]

FLUX.1 Redux [dev] helps you explore variations of existing images. Give it an image and a description of what you want to change, and it creates new versions that maintain the essence of the original while incorporating your changes. Perfect for iterating on designs or exploring creative directions.

If you generate images on Replicate with FLUX.1 models and their fine-tunes, then you can use the images commercially.

If you download the weights off Replicate and generate images on your own computer, you can’t use the images commercially.
