Ultra Upscaler

Personal upscaler. With the default settings, 720p images (realistic) with a good amount of detail work best. For anime and other content, lower settings may suffice. However, you are free to change the parameters.

AI-generated commentary

AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.

Purpose

Ultra Upscaler is a workflow for upscaling images: give it an image and it produces an upscaled image. Its defaults are described as best suited to detailed, realistic 720p images; anime and other content may suit lower settings.

Inputs and outputs

Input: an image. Output: an upscaled image.

Setup

It uses SDXL 1.0 as its base model.

Dependencies

The named model files are bbox/face_yolov8m.pt, controlnet-tile-sdxl-1.0.safetensors, epicrealismXL_vxviiCrystalclear.safetensors, and sdxl_lightning_8step_lora.safetensors.
The named node packs are comfyui_essentials, comfyui-impact-pack, comfyui-impact-subpack, comfyui-kjnodes, and comfyui-wd14-tagger.

Configuration

Adjust First Stage Denoise and Second Stage Denoise to control how much the model re-imagines details.
Higher values add more detail but can alter the image more; the described range is 0.4–0.7.

Cautions

Before use, verify that bbox/face_yolov8m.pt and the other named model files and node packs are available in your workflow environment.
Suggestion · not verified
If you increase either denoise value, inspect the result because higher values can alter the image more.
