Wan2.1 is a cutting-edge video foundation model that excels in image-to-video generation. It outperforms existing open-source and state-of-the-art commercial solutions. The I2V-14B model can generate high-definition 720P videos and has surpassed other models in human evaluations.
SOTA Performance: Consistently outperforms existing open-source and commercial models across multiple benchmarks.
Powerful Video VAE: Wan-VAE delivers exceptional efficiency and performance, encoding and decoding 1080P videos of any length while preserving temporal information.
Architecture: Designed on the mainstream diffusion transformer paradigm with innovations like a novel spatio-temporal variational autoencoder (VAE).
Data: Trained on a vast amount of curated and deduplicated image and video data, processed through a four-step data cleaning process.
The models are licensed under the Apache 2.0 License.
This version can generate videos at 720P resolution.
Extensive manual evaluations confirm that Wan2.1 outperforms both closed-source and open-source models.
