Stable Diffusion is an open-source latent diffusion model that generates high-resolution images from text descriptions through a denoising process in compressed latent space rather than directly in pixel space. This deep learning architecture employs a variational autoencoder to encode images into lower-dimensional representations, then uses a U-Net neural network to progressively remove noise guided by CLIP text embeddings. The model operates through forward diffusion that adds Gaussian noise to training images and reverse diffusion that learns to denoise, enabling controllable image generation. Stable Diffusion supports various tasks including text-to-image synthesis, image-to-image translation, inpainting, and outpainting through different sampling methods like DDIM and DPM-Solver. Its open-source nature enables customization, fine-tuning, and commercial deployment without licensing restrictions. For AI agents, Stable Diffusion provides visual content generation capabilities essential for creative workflows, automated design systems, and multimodal applications requiring dynamic image synthesis.
