The Stable Cascade project is a software initiative aimed at providing an efficient architecture for large-scale text-to-image diffusion models. The project is built upon the Würstchen architecture and focuses on working with a highly compressed latent space, which allows for faster inference and cheaper training compared to other models like Stable Diffusion.
The project consists of three models (Stage A, Stage B, and Stage C) that work together to generate images based on text prompts. Stage A and B compress images, while Stage C generates the small 24 x 24 latents given a text prompt. The project offers a variety of models with different parameter sizes, with the recommendation to use the larger variants for best results.
The repository provides scripts for training and inference, as well as notebooks for different use cases such as text-to-image, ControlNet, LoRA, and image reconstruction. The codebase is in early development and may have issues or areas that are not fully optimized.
