# ComfyUI-GGUF
|
|
GGUF Quantization support for native ComfyUI models
|
|
|
|
This is currently very much WIP. These custom nodes provide support for model files stored in the GGUF format popularized by [llama.cpp](https://github.com/ggerganov/llama.cpp).
|
|
|
|
While quantization wasn't feasible for regular UNET models (conv2d), transformer/DiT models such as flux seem less affected by quantization. This allows running it in much lower bits per weight variable bitrate quants on low-end GPUs.

|
## Installation
|
|
|
|
To install the custom node, clone it to your custom_nodes ComfyUI folder using the following command:
|
|
|
|
```
|
|
git clone https://github.com/city96/ComfyUI-GGUF custom_nodes/ComfyUI-GGUF
|
|
```
|
|
|
|
To install the required `gguf` python package on the standalone ComfyUI, use the following:
|
|
```
|
|
.\python_embeded\python.exe -s -m pip install -r .\ComfyUI\custom_nodes\ComfyUI-GGUF\requirements.txt
|
|
```
|
|
|
|
## Usage
|
|
|
|
Simply use the GGUF Unet loader found under the `bootleg` category. You can find [pre-quantized models for flux1-dev here](https://huggingface.co/city96/FLUX.1-dev-gguf) - place these in your `ComfyUI/models/unet` folder.
