Wan: Open and Advanced Large-Scale Video Generative Models
This report presents Wan, a comprehensive and open suite of video foundation
models designed to push the boundaries of video generation. Built upon the
mainstream diffusion transformer paradigm, Wan achieves significant
advancements in generative capabilities through a series of innovations,
including our novel VAE, scalable pre-training strategies, large-scale data
curation, and automated evaluation metrics. These contributions collectively
enhance the model's performance and versatility. Specifically, Wan is
characterized by four key features: Leading Performance: The 14B model of Wan,
trained on a vast dataset comprising billions of images and videos,
demonstrates the scaling laws of video generation with respect to both data and
model size. It consistently outperforms the existing open-source models as well
as state-of-the-art commercial solutions across multiple internal and external
benchmarks, demonstrating a clear and significant performance superiority.
Comprehensiveness: Wan offers two capable models, i.e., 1.3B and 14B
parameters, for efficiency and effectiveness respectively. It also covers
multiple downstream applications, including image-to-video, instruction-guided
video editing, and personal video generation, encompassing up to eight tasks.
Consumer-Grade Efficiency: The 1.3B model demonstrates exceptional resource
efficiency, requiring only 8.19 GB VRAM, making it compatible with a wide range
of consumer-grade GPUs. Openness: We open-source the entire series of Wan,
including source code and all models, with the goal of fostering the growth of
the video generation community. This openness seeks to significantly expand the
creative possibilities of video production in the industry and provide academia
with high-quality video foundation models. All the code and models are
available at https://github.com/Wan-Video/Wan2.1.
