Stable Diffusion 1.5

Stable Diffusion is a state-of-the-art text-to-image model that creates stunning AI-powered design and illustration in a fraction of the time of previous models. It is a true breakthrough in speed and quality.

Stable Diffusion is a diffusion model, which is a type of image generation model that gradually builds a coherent image from a noise vector by gradually modifying it over a number of steps.

Thanks to a generous compute donation from Stability AI and support from LAION, Stable Diffusion was able to train on 512x512 images from a subset of the LAION-5B database.

Similar to Google's Imagen, this model uses a frozen CLIP ViT-L/14 text encoder to condition the model on text prompts. With its 860M UNet and 123M text encoder, the model is relatively lightweight and runs on a GPU with at least 10GB VRAM.
