ComfyUI Windows Installation

How ComfyUI Windows Installation works on Windows

First-time installation checklists for Windows 10 and 11, PyTorch CUDA 12.4 wheels, Git setup, and shared checkpoint folders. Getting from /download to your first rendered image with verified GPU acceleration and clean dependencies.

Every page in this directory focuses on practical local execution on Windows 10 and Windows 11, keeping your checkpoints, LoRAs, and generated outputs entirely on your own SSD.

Start by grabbing the current Windows build from /download, or browse the guides and node blueprints linked below.

Key workflow principles

• Keep large `.safetensors` and `.gguf` weights inside organized `models/` subfolders or map shared directories through extra_model_paths.yaml.
• Match your model precision (FP16, FP8 e4m3fn, or GGUF Q4/Q8) to your card's VRAM tier so sampling stays in GPU memory without paging to disk.
• Drag any generated PNG directly onto the ComfyUI Studio canvas to reload its exact node wiring, seed, and sampler values.
