What is Wan 2.2?

Wan 2.2 represents the latest evolution in Alibaba's groundbreaking AI video generation technology. As the successor to the highly successful Wan 2.1, this advanced model introduces revolutionary architectural improvements and enhanced capabilities that push the boundaries of AI-powered video creation.

Developed by Wan AI (part of Alibaba), Wan 2.2 is an open-source AI video generation model that transforms text prompts and static images into high-quality, dynamic videos. What sets Wan 2.2 apart is its innovative Mixture-of-Experts (MoE) architecture, which enables more sophisticated video generation while maintaining computational efficiency.

The WanVideo Official Site continues to serve as the primary platform for accessing these powerful tools, now featuring both Wan 2.1 and the new Wan 2.2 capabilities for users seeking the cutting edge of AI video generation.

Key Innovations in Wan 2.2

Wan 2.2 introduces several groundbreaking features that significantly advance beyond Wan 2.1's capabilities:

Effective MoE Architecture

The most significant innovation in Wan 2.2 is its Mixture-of-Experts (MoE) architecture. This system divides the denoising process across timesteps with specialized expert models:

• High-noise experts: Handle the overall layout and structure of the video during early denoising stages
• Low-noise experts: Refine details and ensure high-quality output during later stages

This architecture allows the A14B models to have 27B total parameters while only activating 14B per step, dramatically increasing model capacity without proportional computational cost increases.

Cinematic-level Aesthetic Control

Wan 2.2 incorporates meticulously curated aesthetic data with detailed labels for:

• Lighting conditions and atmospheric effects
• Composition techniques and framing styles
• Contrast and color tone adjustments
• Cinematic styles and visual aesthetics

This enables precise control over video aesthetics at a professional cinematic level, far exceeding Wan 2.1's capabilities.

Large-scale Complex Motion Generation

Training improvements include:

• +65.6% more images compared to Wan 2.1's training dataset
• +83.2% more videos for enhanced motion understanding
• Significantly improved handling of complex movements and interactions
• Better temporal consistency across longer video sequences

Precise Semantic Compliance

Wan 2.2 offers enhanced understanding of:

• Complex multi-object scenes
• Detailed semantic relationships
• Improved restoration of creative intent from prompts
• Better adherence to specific instructions and descriptions

Wan 2.1 vs Wan 2.2: Architecture Comparison

Wan 2.1 Architecture

Wan 2.1 utilizes a traditional diffusion-based approach with:

• Standard Diffusion Transformer (DiT) for video generation
• Wan-VAE for efficient video encoding/decoding
• Single-model architecture processing all denoising stages uniformly
• Proven performance with benchmark scores of 0.724 on Wan-Bench

Wan 2.2 Architecture

Wan 2.2 revolutionizes this with:

• Mixture-of-Experts (MoE) specialized processing
• Dual-expert system for high-noise and low-noise stages
• Enhanced compression technology especially in the 5B model
• Optimized VRAM usage for better hardware accessibility

Performance and Quality Improvements

Video Quality Enhancements

Wan 2.2 delivers significant improvements in:

• Motion Realism: Enhanced handling of complex movements with smoother transitions
• Temporal Consistency: Better frame-to-frame coherence across video sequences
• Detail Preservation: Improved fine detail retention throughout generation process
• Semantic Accuracy: More precise interpretation and execution of text prompts

Efficiency Improvements

Resource Optimization:

• The TI2V-5B model can run on GPUs with as low as 8GB VRAM
• High-compression VAE reduces memory footprint
• Optimized workflows for better hardware utilization
• Faster convergence during the generation process

Generation Speed:

• The TI2V-5B model generates a 5-second 720P video in under 9 minutes on RTX 4090
• Improved efficiency allows for more generations within the same time frame
• Better resource management enables simultaneous processing
