FAQ
- What is Wan2.1?
Wan2.1 (Tongyi Wanxiang 2.1) is Alibaba Cloud’s open-source video generation foundation model released under the Apache 2.0 license. It specializes in text-to-video (T2V) and image-to-video (I2V) generation, leveraging advanced architectures like 3D Causal VAE and Diffusion Transformer (DiT) to produce high-quality, temporally consistent videos with cinematic effects and realistic physics simulations.
- Is commercial use allowed?
Yes. Under Apache 2.0 license, Wan2.1-generated videos can be monetized in ads/films without attribution.
- Minimum hardware requirements?
1.3B model runs on 8GB GPUs (e.g. RTX 3060) for 480P; 14B requires 80GB VRAM for 720P.
- Max video duration?
Infinite-length 1080P via temporal chunking + causal attention.
- Unique Chinese capabilities?
First model supporting calligraphy animations and poetry visualizations.
