Fast Stable Diffusion CLI
Powered by Hugging Face & Diffusers
Designed for Linux
MDX | 0.9.4 |
---|---|
Python | 3.11 - 3.12 |
Torch | cu121 |
Diffusers | 0.30.0 |
Gradio | 4.37.2 |
MDX is tested-stable and maintained for low-end hardware, if quality is what you want, you'll need to use online services or pick up heavier models like Flux.
- SD, SDXL
- Load VAE and LoRA weights
- Txt2Img, Img2Img, Inpaint (auto-pipeline)
- TAESD latents preview (image and animation)
- Batch image generation, multiple images per prompt
- Read/write PNG metadata, auto-rename files
- CPU, GPU, Low VRAM mode (load SDXL with 4 GB)
- Lightweight and fast, rewritten in 300 lines
- Proxy, offline mode, minimal downloads
- Gradio user-interface (mdx-ui.py)
- Real-ESRGAN x2 and x4 script (mdx-upscale.py)
- 3.5 GB python packages (5.5 GB extracted)
- Compatible with most diffusers-based python venvs
- Make sure you have a swap partition or swap file

# Automatic installation:
sudo apt install python3-pip python3-venv
sh install-venv.sh
# Manual installation:
python3 -m venv ~/.venv/mdx
source ~/.venv/mdx/bin/activate
pip install torch torchvision --extra-index-url https://download.pytorch.org/whl/cu121
pip install -r ./requirements.txt
deactivate
Install Gradio and Zenity for user-interface:
~/.venv/mdx/bin/python3 -m pip install gradio==4.37.2
sudo apt install zenity
* Zenity: If you don't have a GNOME desktop, you can't use the file dialog to select .safetensors files, you have to enter the Checkpoint, LoRA and VAE path manually.

Import MDX class to inference from JSON data
from mdx import MDX
data = json.loads(data)
data["prompt"] = "new prompt"
parser = argparse.ArgumentParser()
args = parser.parse_args(namespace=argparse.Namespace(**data))
MDX().main(args)
Inference can be interrupted by creating a file named ".interrupt" in the --output directory. (e.g. mdx-ui.py)
* Enable OFFLINE if you have already downloaded the huggingface cache
* Enable SAVE_ANIM to save the preview animation to {output}/filename.webp
* Model may be slow to load on first launch, but reloading SDXL with 4GB only takes a second
Preview, cancel, and repeat faster:
mdx -p "prompt" -g 8.0 -st 30 -pv
mdx -p "prompt" -g 8.0 -st 30 -s 827362763262387
Content-aware upscaling: (ImageMagick)
mdx -p "prompt" -st 20 -w 512 -h 512 -f image
magick convert ~/.mdx/image.png -resize 200% ~/.mdx/image_up.png
mdx -p "prompt" -st 20 -i ~/.mdx/image_up.png -sr 0.5
Generate 40 images in less time:
mdx -p "prompt" -b 10 -no 4
Extract images from WebP animation: (ImageMagick)
magick convert image.webp jpg
Explore output directory in a browser across the LAN:
cd ~/.mdx && python3 -m http.server 8000
$ open http://192.168.x.x:8000
Download huggingface cache in a specific path:
mkdir ~/.hfcache && ln -s ~/.hfcache ~/.cache/huggingface
