How to Install and Use ComfyUI on Windows - Complete Guide

What is ComfyUI?

While Stable Diffusion WebUI has been the go-to tool for text-to-image generation, requiring configuration of multiple settings across different modules, ComfyUI offers a more intuitive approach. It uses a visual node-based workflow that makes the text-to-image process more efficient and user-friendly.

Basic Installation Guide for Windows

Required Downloads

• Windows All-in-One Package
• 7-Zip Extraction Tool

Installation Steps

1. Download and extract the package using 7-Zip

Pre-launch Configuration

If you need external access after launch, right-click and edit either run_cpu.bat (for CPU) or run_nvidia_gpu.bat (for GPU) and add the parameter --listen 0.0.0.0 Example of modified run_nvidia_gpu.bat :

 .\python_embeded\python.exe -s ComfyUI\main.py --windows-standalone-build --listen 0.0.0.0
pause  

Launching ComfyUI

Double-click either run_cpu.bat (CPU) or run_nvidia_gpu.bat (GPU) to start. If successful, your default browser will open to http://127.0.0.1:8188 , displaying the ComfyUI interface.

ComfyUI stores models in ComfyUI_windows_portable_nvidia\ComfyUI_windows_portable\ComfyUI\models\checkpoints

Download your preferred models (refer to our Stable Diffusion Models Overview for recommendations) and place them in the checkpoints folder. Restart the service to see your models in the dropdown menu:
