? Sharpening upscaler
⏬ Sharpening upscaler
Add details to an image to boost its resolution. Only one upscaler model is used in the workflow.
? Creative upscaler
⏬ Creative upscaler
Add more details with AI imagination. The output looks better, elements in the image may vary.
Low denoise value for latent image and ControlNet to keep the composition.
When it does not work for you, try adjusting ControlNet weight and denoise.

Citation
Special thanks to clarity-upscaler which inspired my workflow! Clarity-upscaler is based on A1111 and has not offered ComfyUI workflow yet(update:now it has). I played with the models it uses and somehow created my own simplified alternative. I have to say that mine is not as good as the original clarity-upscaler, but it works for me.
