Introduction

We explore the Reward Backpropagation technique 1 2 to optimized the generated videos by Wan2.2-Fun for better alignment with human preferences. We provide the following pre-trained models (i.e. LoRAs) along with the training script. You can use these LoRAs to enhance the corresponding base model as a plug-in or train your own reward LoRA.

For more details, please refer to our GitHub repo.

Official MPS reward LoRA (rank=128 and network_alpha=64) for Wan2.2-Fun-A14B-InP (low noise). It is trained with a batch size of 8 for 4,500 steps.
