Upscale images with ComfyUI cloud workflows

Demo summary
The user demonstrates an upscaler workflow on Running Hub, showing how to adjust the denoise value to add detail while increasing image resolution.
Step-by-step
- Launch the upscaler workflow on Running Hub
- Upload your image to the workflow
- Add a prompt to describe the image
- Adjust the denoise value based on your desired level of detail
- Compare the original and upscaled versions by moving the mouse over the output
Options
- Set denoise to 0.8 to stay similar to the original
- Increase denoise to 0.95 to allow the AI more freedom to add new details
- Lower the denoise value below 0.8 for less variation
Watch out for
- The upscaler can sometimes add too much sharpness with no direct way to control it
- Results are random and vary significantly depending on the specific image and AI training
Tips
- Use a higher denoise value if you don't need the output to be perfectly identical to the original
- Compare the 2x and 4x upscaled versions to see which resolution handles the detail better
Highlights
“for some images it does a good job while for others not so much um it's always random with AI”
