ComfyUI Guides

How ComfyUI Guides works on Windows

In-depth Windows guides covering VRAM optimization, FP8 and GGUF quantization, workflow JSON sharing, and multi-GPU setups. Step-by-step architectural guides for stable generation on 8 GB, 12 GB, 16 GB, and 24 GB NVIDIA RTX cards.

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.
