FAQs
Can ComfyUI and ComfyUI Portable 7z Build share the same models folder on Windows?
Yes. Edit `extra_model_paths.yaml` in your ComfyUI root folder to point `base_path` at your existing models directory so both apps load the exact same files.
Does ComfyUI use less VRAM than ComfyUI Portable 7z Build?
ComfyUI only keeps the active node's sub-model (CLIP, UNet, or VAE) in VRAM at each step and supports native FP8 and GGUF quantization, making it significantly lighter on 8 GB and 12 GB GPUs.
