Wan 2.2

Wan 2.2 is Alibaba's Tongyi Lab open-source video model, released under a permissive Apache-2.0 license — you can download the weights, run them on your own hardware, and use the output commercially with no per-clip fee. It uses a mixture-of-experts (MoE) architecture and is the most versatile open model available: it handles both text-to-video and image-to-video (animate a still photo), producing 720p-1080p clips around 5 seconds long. This is the model to reach for if you want to understand how video generation actually works under the hood, or if you're generating enough clips that per-clip API costs would add up. The real cost is hardware: you need a GPU with at least 24GB of VRAM to run it comfortably, which usually means a rented cloud GPU (see the Inference providers chapter) rather than a laptop. Setup typically goes through ComfyUI, a node-based interface for running these models.
