I am using my new Gradio written web user interface for upscaling images. The challenge was to transfer the Exif metadata from the original image to the upscaled image in such a way that CIVITAI can read the data. As one sees, it works now very well. I did not use AI for upscaling in this case. The standard possibilities for upscaling works also well. The advantage of these methods is, that they are quite fast.
