Your personal AI artist, running on your own computer
Stable Diffusion WebUI puts professional AI image generation on your desktop. Unlike cloud-based services like Midjourney or DALL-E, your images stay private on your computer. There are no credit systems, no usage limits, and no content restrictions — generate as many images as you want.
Hardware note: Best experience requires an NVIDIA GPU with 6GB+ VRAM. Mac and CPU-only users can still use it, but generation will be slower.
System Requirements
| Level | Hardware | Experience |
|---|---|---|
| Recommended | NVIDIA RTX 3060+ 12GB, 16GB RAM, 20GB disk | Fast 1024x1024 generation |
| Minimum | NVIDIA GTX 1060 6GB, 8GB RAM | Usable 512x512, moderate speed |
| Mac | M1/M2/M3 chip, 16GB RAM | Works, slower than NVIDIA |
| No GPU | CPU-only mode or cloud GPU | Slow but functional |
FAQ
How long does one image take? Around 3-5 seconds for 512x512 on an RTX 3060. Faster GPUs are quicker. CPU-only mode may take several minutes per image.
Do prompts need to be in English? English works best because the base model was trained on English-labeled data. You can use translation tools to convert Chinese prompts, or download community models fine-tuned for Chinese.
Can I use generated images commercially? Depends on the model license. The base Stable Diffusion model uses the Creative ML OpenRAIL-M license, which allows commercial use with some restrictions. Always check individual model licenses.
Why does the first launch take so long? The initial setup downloads about 5-10 GB of dependencies including the AI model. After the first setup, subsequent launches take about 30 seconds.
