Stable Diffusion is a latent diffusion model released by Stability AI that can run locally on consumer GPUs, offering complete creative freedom with no content restrictions. SDXL and SD3 variants significantly improved image quality and prompt understanding. The ecosystem includes thousands of community fine-tunes, LoRA adapters, and ControlNet modules on Civitai. Interfaces like ComfyUI, Automatic1111, and InvokeAI make it accessible to non-coders.
