## What ComfyUI-GGUF Loader Nodes does in a ComfyUI graph

Loads quantized GGUF diffusion and T5 weights directly into ComfyUI so 8 GB and 12 GB GPUs can run Flux and Hunyuan Video.

On the canvas, this node accepts `unet_name (.gguf), clip_name1, clip_name2` and emits `MODEL, CLIP`. Every pin is color-coded by data type so you cannot accidentally wire a pixel `IMAGE` tensor into a `LATENT` pin without an intermediate encode step.
