The paper introduces Uni-Instruct, a theory-driven framework that unifies over 10 existing one-step diffusion distillation approaches.
Uni-Instruct is inspired by a proposed diffusion expansion theory of the $f$-divergence family to effectively train one-step diffusion models.
Uni-Instruct achieves record-breaking Frechet Inception Distance (FID) values on benchmarks like CIFAR10 and ImageNet-$64 imes 64$, outperforming previous methods.
The application of Uni-Instruct on text-to-3D generation also shows improved generation quality and diversity compared to existing methods such as SDS and VSD.
