Topaz Image Enhance Wonder 4 is an image upscaling model available in ComfyUI through the Topaz partner nodes. It rebuilds plausible detail instead of stretching pixels, so a small, soft image comes back clean at up to six times its size. It keeps the input aspect ratio and accepts upscale factors from 1x to 6x.

​
What Topaz Image Enhance Wonder 4 is good at

  • Detail reconstruction: Rebuilds plausible detail in soft or compressed images instead of interpolating pixels
  • Single pass: One pass at the target size, with no strength or grain settings to tune
  • Recovering small sources: Useful for old scans, screenshots, AI thumbnails, and phone crops
  • Flexible output: Keeps the input aspect ratio and accepts upscale factors from 1x to 6x
To use the Partner Nodes, you need to ensure that you are logged in properly and using a permitted network environment. Please refer to the Partner Nodes Overview section of the documentation to understand the specific requirements for using the Partner Nodes.
Make sure your ComfyUI is updated.Workflows in this guide can be found in the Workflow Templates. If you can’t find them in the template, your ComfyUI may be outdated.If nodes are missing when loading a workflow, possible reasons:
  1. You are not using the latest ComfyUI version (Nightly version)
  2. Some nodes failed to import at startup

Controls

Wonder 4 keeps the source aspect ratio: when the requested width and height disagree, the larger scale wins and the output is bigger than requested. Output is capped at 179 megapixels and 32,000 pixels per side, and the node downscales the input to about 16 megapixels before sending it.

​
Steps to run

  1. Load an image: upload or select your input image in the LoadImage node
  2. Select the model: keep Wonder 4 on the TopazImageEnhanceV2 node
  3. Set the target size: change scale_by on the ImageScaleBy node, from 1x to 6x
  4. Optional override: enter a pixel size in output_width or output_height on the node (leave both at 0 to keep the automatic size)
  5. Click Queue: press Ctrl+Enter to generate

​
When to use it

Reach for Wonder 4 on small, medium, soft, noisy, or compressed images: old scans, screenshots, AI thumbnails, and phone crops. A graphic, textured image is a good test, because torn edges, seams, and flat color fields show at once whether the model invents detail or keeps the original. For an already sharp, high-resolution photo, a precision upscaler keeps more of the original.
