# NVIDIA NIM SDXL
|
||
|
||
### What is Stable Diffusion XL NIM?
|
||
|
||
The Stable Diffusion XL NIM is a container that allows you to run Stability.AI’s Stable Diffusion XL model - one of the most popular visual generative AI models in the world - in the most optimal manner.
|
||
|
||
## Getting Started with Stable Diffusion XL NIM with ComfyUI
|
||
|
||
Before installing, ensure your system meets the following requirements:
|
||
Operating System: Windows 11 (22H1 or later)
|
||
GPU: AD100 or above
|
||
GPU Driver: Version 565.xx or later
|
||
Virtualization Settings: Enabled in SBIOS - [Instructions to enable virtualization if it is not enabled](https://support.microsoft.com/en-gb/windows/enable-virtualization-on-windows-c5578302-6e43-4b4b-a449-8ced115f58e1)
|
||
|
||
|
||
The node can automatically download and run the NVIDIA NIM installer for you when you install the node via ComfyUI Manager.
|
||
Alternatively you can download and run the the installer from here:
|
||
https://storage.googleapis.com/comfy-assets/NimSetup.exe
|
||
|
||
After NIM is installed (via automatic process or manual - note that these steps will be streamlined in future), please perform the following steps:
|
||
|
||
1. Open the Terminal app
|
||
|
||
2. Open the NVIDIA-Workbench profile by clicking on the arrow along the top
|
||
|
||
3. Setup NIM directories by running the following commands
|
||
```
|
||
export LOCAL_NIM_CACHE=~/.cache/nim
|
||
mkdir -p "$LOCAL_NIM_CACHE"
|
||
chmod -R a+w "$LOCAL_NIM_CACHE"
|
||
```
|
||
|
||
### Install node in ComfyUI
|
||
The recommended way to install these nodes is to use the [ComfyUI Manager](https://github.com/ltdrdata/ComfyUI-Manager) to easily install them to your ComfyUI instance.
|
||
You can also manually install them by git cloning the repo to your ComfyUI/custom_nodes folder
|
||
|
||
## Usage
|
||
You will need to start the container each time you want to use the node.
|
||
To do this, navigate to the NVIDIA-Workbench profile in Terminal (see getting started section) and run the following command:
|
||
```
|
||
podman run -it --rm \
|
||
--device=nvidia.com/gpu=all \
|
||
--shm-size=16GB \
|
||
-e NGC_API_KEY=$NGC_API_KEY \
|
||
-v "$LOCAL_NIM_CACHE:/opt/nim/.cache" \
|
||
-u $(id -u) \
|
||
-p 8000:8000 \
|
||
{todo: URL}
|
||
```
|
||
The first time you run this it will download and configure the container, this may take a while.
|
||
|
||
After the container is running you can then simply add the NIM SDXL node to generate images, download the [example workflow here](example_workflows/sdxl_nim_workflow.json) or you can drag the image below into ComfyUI to view the embedded workflow:
