# Wan 2.2 — on dedicated hardware, by Spacelike AI

_MoE video diffusion · 27 B total / 14 B active · Alibaba Tongyi Lab_

Wan 2.2, released July 28, 2025, is the **first open-source video diffusion model with a Mixture-of-Experts backbone**. The T2V-A14B variant routes between a *high-noise expert* (early denoising / layout) and a *low-noise expert* (late denoising / detail) based on signal-to-noise ratio, giving it 27 B total parameters while using only 14 B per step.

A companion 5 B dense model (TI2V-5B) pairs a 4×16×16 high-compression 3D VAE with a unified text- and image-to-video head, generating 720p 24 fps clips on a single consumer GPU. Shown here is a single-frame sample from an A14B text-to-video trace.
