Radiant Gradients requires iOS 26, iPadOS 26, and macOS 26
There is an issue with the way macOS caches wallpapers where you can end up with a large amount of old wallpapers on disk. These are stored at: ~/Library/Containers/com.apple.wallpaper.agent/Data/Library/Caches/com.apple.wallpaper.caches/extension-com.apple.wallpaper.extension.image
To browse to this folder in Finder select the Go menu and hold Option which will reveal the Library menu item. Opening Library, you can browse from there. Alternatively in the Go menu select Go to Folder… and paste the file path.
Since this is a cache you are free to delete files within this folder. If you have a frequent refresh interval you will need to clean this folder out regularly.
That is determined by the Apple Intelligence system but it is a lightweight prompt so most likely uses the on-device model.
You can with the Custom colour mode.
You will need to use Shortcuts. A step-by-step guide can be found inside the app.
No, Radiant Gradients is a free download with a one-off purchase to unlock full functionality.
