Wan2.1
Apache-2.0 open video generation in 1.3B and 14B sizes.
About
Wan2.1 is Alibaba's open video-generation model family, with a 1.3B variant that runs on consumer GPUs and a 14B variant for higher fidelity, covering text-to-video, image-to-video, and video editing. It is Apache-2.0 licensed, which made it one of the most widely adopted open video models of 2025. The smaller model is genuinely usable on a single card, though it trades away detail, and like all open video models it still struggles with long coherent motion. A 2.2 generation followed later with a mixture-of-experts design.
