Stable Diffusion
The most widely used open-source image generation model, enabling local deployment, fine-tuning, and an extensive ecosystem of community extensions.
Overview
Stable Diffusion is an open-source latent diffusion model for image generation that has become the foundation of the open-source AI art ecosystem. Unlike closed alternatives, it can be run locally on consumer hardware, fine-tuned on custom datasets, and modified through a vast ecosystem of community-built extensions, LoRAs, and tools like Automatic1111 and ComfyUI. Stable Diffusion XL and SD 3.0 brought significant quality improvements, while the open nature of the project has spawned thousands of specialized model variants for every conceivable use case.
