Stable Cascade is a text-to-image generation model based on the Würstchen architecture. Compared to other models, it uses a smaller latent space for training and inference, resulting in significant improvements in both training and inference speed. The model can run on consumer-grade hardware, lowering the barrier to entry. Stable Cascade has shown outstanding performance in human evaluations, outperforming other models in both prompt alignment and image quality. Overall, it is an efficient, user-friendly, and powerful text-to-image AI model.
