How to Install Uncensored Stable Diffusion with ComfyUI

Simple, Direct Setup Guide (With Optional NSFW Tools)

This guide is for people who want to run Stable Diffusion locally using ComfyUI, with full access to uncensored models — no filters, no limitations. Whether you’re making SFW art, experimenting with style, or generating NSFW content, this covers everything you need to get started quickly.

This walkthrough is written in plain language, aimed at Reddit users and hobbyists who want things to work without spending hours reading GitHub docs.

What You’ll Need :

  • Windows PC (Linux works too, but this guide is for Windows)

  • NVIDIA GPU with at least 6GB of VRAM

  • 20–30GB free space

  • Basic file handling skills (you’ll be dragging folders and running .bat files)

Step 1: Download & Set Up ComfyUI

  1. Go to the official repo:
     👉 https://github.com/comfyanonymous/ComfyUI
     Click “Code > Download ZIP” and extract it somewhere (e.g., C:\ComfyUI).

  2. Inside that folder:

    • Run update_python.bat to install dependencies.

    • Then run run_nvidia_gpu.bat to launch ComfyUI.

That’s it — the interface will open in your browser at:
 http://127.0.0.1:8188

Step 2: Install a Model (Uncensored)

  • By default, ComfyUI doesn’t come with any models. You’ll need to add one manually.
  • If you want to generate NSFW or adult content, use an uncensored model like:
    • Anything V5 / AOM3 – anime-style, no filters

    • RealisticVision – photorealism, supports nudity

    • Deliberate – balanced style for general use

    • You can find these models on:
  • Once downloaded, place the .safetensors file into this folder:
  • CopyEdit
    • ComfyUI\models\checkpoints
  • Alternative: If you don’t want to deal with downloading and installing models locally, you can use an online service that handles it all for you.

Step 3: Add a VAE (Optional, But Recommended)

  • Some models need a VAE to render skin tones, lighting, and colors properly.
  1. Download a VAE like:
     vae-ft-mse-840000-ema-pruned.safetensors

  2. Place it in:
    1. CopyEdit
      1. ComfyUI\models\vae
  3. Then select it in the interface when generating images.

Step 4: Using ComfyUI

  • To generate images:
  1. Launch ComfyUI by running run_nvidia_gpu.bat

  2. It will open in your browser automatically

  3. Load a workflow (drag-and-drop or use the “Load” option)

  4. Choose your model and enter a prompt

  5. Click Queue Prompt to start generating

  • ComfyUI saves images automatically and shows you the full history of generations.

Optional: Browser-Based NSFW Tools

  • If your goal is mainly NSFW content and you don’t have a powerful PC (or just want something easier), consider using one of these uncensored AI art sites:
    • Instant NSFW image generator – create content online without restrictions (affiliate)

    • GIF and animation AI tool – generate NSFW animated scenes from prompts (affiliate)

    • Prompt-based erotic character builder – quick and private browser-based art tool (affiliate)

  • These platforms require no setup, and are ideal if you just want to experiment or create content without learning the full ComfyUI interface.

Optional: Install Extra Nodes and Features

  • ComfyUI supports custom nodes to expand its functionality.
  • You can install:
    • ComfyUI Manager – lets you install models and extensions through the UI

    • Impact Pack – adds prompt editing, refinements, etc.

    • CNodeSuite – randomizers, upscalers, etc.

  • To install:
  1. Download a node pack from GitHub.

  2. Place the entire folder into:

  • CopyEdit    ComfyUI\custom_nodes
  • Restart ComfyUI — the new tools will now appear.

TL;DR

  • Download ComfyUI and run run_nvidia_gpu.bat

  • Add an uncensored .safetensors model to the /checkpoints/ folder

  • Add a VAE for better image quality

  • Generate images using workflows and prompt input
