An open‑source text-to-image diffusion model that generates photorealistic images from prompts, accessible locally or via API
Stable Diffusion is a landmark open‑source latent diffusion model, released in August 2022 by Stability AI in collaboration with CompVis, Runway, EleutherAI, and LAION. It uses a Variational Autoencoder (VAE), a modified U-Net (or Transformer in SD3), and a text encoder (typically CLIP) to convert text prompts (and optionally images) into detailed, photorealistic visuals through a denoising process that reverses adding noise. Stable Diffusion supports text-to-image, image-to-image transformations, inpainting, outpainting, and has even been adapted for video generation and animations via extensions and downstream models. Its open-source nature makes it highly accessible—runnable on GPUs with moderate VRAM—and customizable for developers, creatives, researchers, and enterprises alike.
