FLUX.1 Expand is documented for expanding images beyond their original boundaries to increase resolution or change aspect ratios.
It is suited to outpainting and panorama creation, including extending a source photograph horizontally into a seamless wide-format image.
It is also suited to adapting images for different formats, such as turning an image into a wide editorial panorama or other campaign-ready aspect ratios.
It is used for adding new pixels on any side of an image, with text guidance for the changes to the expanded areas.
