Wan2.1-T2V-14B-StepDistill-CfgDistill

Overview

Wan2.1-T2V-14B-StepDistill-CfgDistill is an advanced text-to-video generation model built upon the Wan2.1-T2V-14B foundation. This approach allows the model to generate videos with significantly fewer inference steps (4 or 8 steps) and without classifier-free guidance, substantially reducing video generation time while maintaining high quality outputs.

Training

Our training code is modified based on the Self-Forcing repository. We extended support for the Wan2.1-14B-T2V model and performed a 4-step bidirectional distillation process. The modified code is available at Self-Forcing-Plus.

Inference

Our inference framework utilizes lightx2v, a highly efficient inference engine that supports multiple models. This framework significantly accelerates the video generation process while maintaining high quality output.
