Executive Snapshot
| Model | License | Native Resolution & Audio | GPU / Hardware Requirements | Access |
|---|---|---|---|---|
| Wan 2.2 | Apache‑2.0 (Free & Open) | 720p @ 24 fps, No audio | 8 GB (TI2V‑5 B) to 24 GB (A14B) | GitHub, Hugging Face, ComfyUI, web tools |

1. What Is Wan 2.2?
Wan 2.2 is an open‑source video generation model from Alibaba's Tongyi Lab, released in July 2025 under a permissive Apache‑2.0 license. It employs a Mixture-of-Experts (MoE) diffusion transformer with 27 billion parameters, yet only ~14B are active per timestep, enabling high-capacity inference with manageable memory use.
Key highlights:
- Generates 720p 24 fps cinematic video from text or image prompts
- Provides checkpoints like TI2V‑5 B (runs on 8 GB VRAM) and T2V‑A14 B (for 24 GB)
- Ships with richly annotated training data—images and video clips labeled with cinematic tags (lighting, motion, lens, LUT)
- Supports multilingual (English + Chinese) prompt text and clear in-frame rendering

2. What Is VEO 3?
VEO 3 is Google DeepMind's latest AI video model, launched in mid‑2025 via Vertex AI and Gemini. Unlike Wan 2.2, it is not open-source and accessible only via Google's cloud APIs.
Key characteristics:
- Produces 1080p video with native audio, including lip‑synced speech, ambient noise, sound effects, and music
- Includes a physics-aware motion engine for realistic object interaction
- Supports SynthID watermarking, enterprise compliance, and rate-limited API endpoints
- Offers a "Fast" version for quicker render turnaround, ideal for ads or demos

3. Architecture & Dataset Comparison
Wan 2.2
- MoE Transformer with separate expert modules for earlier rough layout and later detail refinement. Only one expert activates per diffusion step, conserving memory
- Training dataset improved over Wan 2.1 by ~65% more images and ~83% more video, particularly capturing handheld motion, film grain, and cinematic styles
- Every video clip is tagged for attributes like lighting conditions, camera lens, movement type, and film stock—enabling fine prompt control
VEO 3
- A hybrid system combining diffusion-based video generation with an autoregressive latent model for coherent motion and sound
- Audio and video are generated jointly—supporting natural lip-sync and realistic ambient environments
- Trained on massive paired video-audio datasets with motion metadata for physics consistency
