About Stable Diffusion

"Open-source AI image generation"

Stable Diffusion is the foundational open-source text-to-image AI model developed by Stability AI that sparked the consumer AI art revolution. Its open-weight release enabled a massive ecosystem of fine-tuned variants, LoRA models, ControlNet extensions, and creative tools built by a global community. Artists and developers run Stable Diffusion locally for complete creative control and privacy, or through platforms like ComfyUI and Automatic1111 for maximum customization. The model's open-source nature has made it the platform that advanced the AI art field most rapidly, with thousands of community-developed extensions expanding its capabilities far beyond the original release.
