Using its delicate strategies of *target timestep selection* and *decoupled guidance*, models distilled by TDD can generated highly detailed images with only a few steps. Besides, TDD is also available for distilling video generation models. This space presents TDD-distilled [SVD-xt 1.1](https://huggingface.co/stabilityai/stable-video-diffusion-img2vid-xt-1-1).
