Wan 2.2 is a multimodal video generation model developed by Alibaba's Tongyi Laboratory and released in July 2025 under the Apache 2.0 license. It is the first video diffusion model to apply a Mixture-of-Experts (MoE) architecture, which splits processing between high-noise expert networks that handle overall layout and composition and low-noise expert networks that refine fine details. The model supports both text-to-video and image-to-video generation, with native bilingual prompting in English and Chinese. It is available in a 5B parameter variant suited for consumer hardware and a 14B parameter variant for higher-quality output.

Wan 2.5 is an open-source AI video generation model developed by Alibaba's DAMO Academy. It produces video clips up to 10 seconds long at resolutions up to 1080p, and generates synchronized audio — including dialogue with lip-sync, ambient sound effects, and background music — alongside the visuals in a single generation step. The model accepts text prompts, still images, audio tracks, or existing video clips as input, and supports cinematic controls such as camera movement types, lighting styles, and depth of field specified directly in the prompt.

Wan 2.5 is an open-source AI video generation model developed by Alibaba's DAMO Academy. It generates videos up to 10 seconds long at resolutions ranging from 480p to 1080p HD, with native 4K available in preview, all rendered at 24 frames per second. The model's defining characteristic is its ability to generate audio and video simultaneously in a single step — producing character dialogue with lip-sync, environmental ambient sounds, and background music directly from a text or image prompt, without requiring separate post-production audio work. It supports multiple input modes including text-to-video, image-to-video, audio-to-video, and video-to-video refinement.
