🔥 News

• 2026.04.12: We are excited to release the Wan2.2-I2V-A14B-4step-720p-high and Wan2.2-I2V-A14B-4step-720p-low models. Compared to previous iterations, this version was trained on a high-quality 720p dataset and features an optimized low-noise training algorithm. These enhancements significantly boost the model's performance in fine-grained detail rendering and visual texture.

🚀 Usage

Method 1: LightX2V (Recommended ⭐)

LightX2V is a high-performance inference framework optimized for these models, approximately 2x faster than ComfyUI with better quantization accuracy. Highly recommended!

Quick Start

1. Download model (using I2V FP8 as example)

huggingface-cli download lightx2v/Wan2.2-Distill-Models \
    --local-dir ./models/wan2.2_i2v \
    --include "wan2.2_i2v_A14b_high_noise_scaled_fp8_e4m3_lightx2v_4step.safetensors"

huggingface-cli download lightx2v/Wan2.2-Distill-Models \
    --local-dir ./models/wan2.2_i2v \
    --include "wan2.2_i2v_A14b_low_noise_scaled_fp8_e4m3_lightx2v_4step.safetensors"

💡 Tip: For T2V models, follow the same steps but replace i2v with t2v in the filenames

2. Clone LightX2V repository

git clone https://github.com/ModelTC/LightX2V.git
cd LightX2V

3. Install dependencies

pip install -r requirements.txt

Or refer to Quick Start Documentation to use docker

4. Select and modify configuration file

Choose appropriate configuration based on your GPU memory:

80GB+ GPUs (A100/H100)

• I2V: wan_moe_i2v_distill.json

24GB+ GPUs (RTX 4090)

• I2V: wan_moe_i2v_distill_4090.json

5. Run inference (using I2V as example)

cd scripts
bash wan22/run_wan22_moe_i2v_distill.sh

📝 Note: Update model paths in the script to point to your Wan2.2 model. Also refer to LightX2V Model Structure Documentation

⚠️ Important Notes

Other Components: These models only contain DIT weights. Additional components needed at runtime:

• T5 text encoder
• CLIP vision encoder
• VAE encoder/decoder
• Tokenizer

Please refer to LightX2V Documentation for instructions on organizing the complete model directory.
