ComfyUI: .gguf downloaded but not showing in the Unet (GGUF) loader — fix

Also seen as: "gguf not showing in ComfyUI", "UnetLoaderGGUF empty dropdown", "gguf model not in list"

Direct answer

How do I fix "a .gguf model missing from the Unet loader"?

You downloaded a GGUF quant but UnetLoaderGGUF shows an empty dropdown or will not list it. This is almost always a folder problem: ComfyUI-GGUF reads a dedicated folder key, and a GGUF dropped in the wrong models subfolder will not appear.

Key facts

  • iThe .gguf is in models/diffusion_models (or elsewhere) instead of the location the GGUF loader scans reliably.
  • iComfyUI-GGUF is not installed or is out of date, so the GGUF loader is not registering its folder at all.
  • iComfyUI was not restarted after adding the file — loader folders are read at startup.

Next step

  1. 1Put the .gguf in models/unet/ — the canonical, reliably-scanned location for GGUF diffusion weights.
  2. 2Confirm ComfyUI-GGUF is installed and current (it supplies UnetLoaderGGUF).
  3. 3Restart ComfyUI and re-open the loader — the dropdown reads the folder at boot.

Not a fit when

  • models/diffusion_models may or may not surface a GGUF depending on your ComfyUI-GGUF version — do not rely on it; use models/unet.
