Source description

I didn't find any workflow that allowed upscaling with Kwai Kolors, so I made my own.

It should be fairly straightforward once you've got the custom nodes installed (I recommend using the ComfyUI manager for that).

Just input your prompt and let the workflow do its job.

The workflow will automatically download the models required.

Conveniently, you can simply mute or unmute the upscale node to avoid wasting time upscaling bad generations.
