Where to put it
Put the file in ComfyUI/models/latent_upscale_models/ (in the portable version: ComfyUI_windows_portable/ComfyUI/models/latent_upscale_models/). Then press R in ComfyUI, or restart it, so the file shows up in the latent-upscale loader used by the model’s official workflow.
If a workflow says “Value not in list” for this node, the file name in the workflow is different from yours, or the file is in another folder. Click the node and pick the file from the list.
What it does
A latent upscaler is used by the two-stage (upscale) workflows. You can skip it for a single-pass render.
Needed only: official two-stage template.
