Upscale images and frame batches with optional tiling and GPU tile blending.

UpscalingImagesVideo frames

What it does

Replace ComfyUI’s Upscale Image (using Model) node while keeping the same model and image connections. Process frames in batches, and leave tiling off when the full image fits in memory.

  • Works with models loaded through Load Upscale Model.
  • Adjust batch size, precision, tile size and overlap.
  • Reduces batch size and falls back to tiling when memory runs out.

Install in ComfyUI

Open a terminal in your ComfyUI folder. For dependency commands, use the Python environment that runs ComfyUI. On Windows Portable, use its bundled Python instead of your system Python.

Terminal
cd custom_nodes
git clone https://github.com/Hearmeman24/ComfyUI-HearmemanAI-Upscale.git

Restart ComfyUI after installation, then refresh the browser to load the nodes.

Before you start

  • An existing ComfyUI installation and a compatible upscale model.
  • Uses ComfyUI’s existing dependencies; no additional package installation is required.
  • Restart ComfyUI, then look for HearmemanAI Upscale Model in the HearmemanAI category.
