I tried ChapGPT and Grok to modify an image. All I wanted was to upscale and extend the edges of this wallpaper to 4K. Instead, it redraws it, changes the text to gobbldygook, and makes it horrible.

I think this one is better quality: https://www.flickr.com/photos/segaamerica/5182705574

If someone could rescale and modify these wallpapers, I'd appreciate it, but I'd like to know how to get the AI to do it myself.
