ComfyUI‑GGUF: Run Low‑Bit Models on Your GPU

Learn how to leverage ComfyUI‑GGUF, an open‑source extension that adds GGUF quantization support to the popular ComfyUI workflow. By loading quantized models in the lightweight GGUF format, you can run recent diffusion architectures such as Flux 1‑Dev or Stable Diffusion 3.5 on modest GPUs while dramatically reducing VRAM usage. This article walks through the installation prerequisites, how to clone the repo into your custom_nodes folder, install the gguf dependency, and replace the standard model loader with the GGUF Unet loader. It also covers pre‑quantized models, experimental LoRA support, and platform‑specific nuances. By the end, you’ll be ready to run cutting‑edge AI models at a fraction of the cost.
