# Run Stable Diffusion 3 on your own machine with ComfyUI

Stable Diffusion 3 (SD3) just dropped and you can [run it in the cloud on Replicate](https://replicate.com/stability-ai/stable-diffusion-3), but it’s also possible to run it locally using ComfyUI right from your own GPU-equipped machine.
## [](https://replicate.com/blog/run-sd3-on-comfyui#what-is-stable-diffusion-3)What is Stable Diffusion 3?
Stable Diffusion 3 (SD3) is the latest version of Stability AI’s tool that creates images from text. It’s faster and makes better images than older versions. SD3 is really good at making complex scenes with lots of details and clear text from the prompt.

## [](https://replicate.com/blog/run-sd3-on-comfyui#what-is-comfyui)What is ComfyUI?
ComfyUI is a graphical user interface (GUI) for Stable Diffusion models like SD3. It lets you connect different AI models (called nodes) together to create custom images, just like connecting Lego blocks. You don’t need to know any code to use it. ComfyUI makes it fun and simple to try out different combinations (called “workflows”) and make unique pictures.
A special thanks to [comfyanonymous](https://github.com/comfyanonymous) for creating ComfyUI and [fofr](https://github.com/fofr) for creating a [Cog compatiable version of it](https://github.com/fofr/cog-comfyui-sd3)
## [](https://replicate.com/blog/run-sd3-on-comfyui#prerequisites)Prerequisites
To follow this guide, you’ll need:
* A GPU-equipped machine (NVIDIA GPU with at least 8GB VRAM recommended)
* The ability to copy and paste into terminal 😉
## [](https://replicate.com/blog/run-sd3-on-comfyui#step-1-install-cog)Step 1: Install Cog
Start by installing [Cog](https://github.com/replicate/cog). It’s a tool that sets up everything you need to package and run a machine learning model in a container environment. Open your terminal and run these commands:
sudo curl -o /usr/local/bin/cog -L “[https://github.com/replicate/cog/releases/latest/download/cog_$(uname](https://github.com/replicate/cog/releases/latest/download/cog_$(uname) -s)_$(uname -m)” sudo chmod +x /usr/local/bin/cog
## [](https://replicate.com/blog/run-sd3-on-comfyui#step-2-clone-the-comfyui-repository)Step 2: Clone the ComfyUI repository
Next, clone the ComfyUI code from GitHub:
git clone —recurse-submodules [git@github.com](mailto:git@github.com):fofr/cog-comfyui-sd3.git cd cog-comfyui-sd3
## [](https://replicate.com/blog/run-sd3-on-comfyui#step-3-start-comfyui)Step 3: Start ComfyUI
Start ComfyUI. Run this command to download weights and start the ComfyUI web server:
sudo cog run —use-cog-base-image -p 8188 /bin/bash -c “python scripts/get_weights.py workflow_api.json && cd ComfyUI/ && python main.py —listen 0.0.0.0”
