Stable Diffusion is based on an image generation technique called latent diffusion models (LDMs). Unlike other popular image synthesis methods such as generative adversarial networks (GANs) and the auto-regressive technique used by DALL-E, LDMs generate images by iteratively "de-noising" data in a latent representation space, then decoding the representation into a full image. LDM was developed by the Machine Vision and Learning research group at the Ludwig Maximilian University of Munich and described in a paper presented at the recent IEEE / CVF Computer Vision and Pattern Recognition Conference (CVPR). Earlier this year, InfoQ covered Google's Imagen model, another diffusion-based image generation AI.

The Stable Diffusion model can support several operations. Like DALL-E, it can be given a text description of a desired image and generate a high-quality that matches that description. It can帮我翻译一下，你上班吗？
