# 🎬 Wan2.2 Distilled Models (SGMD)

This repository contains distilled versions of the Wan2.2 models using **SGMD (Score Gradient Matching Distillation)**, as presented in the paper [SGMD: Score Gradient Matching Distillation for Few-Step Video Diffusion Distillation](https://huggingface.co/papers/2605.30116).

### ⚡ High-Performance Video Generation with 4-Step Inference

*Distillation-accelerated version of Wan2.2 - Dramatically faster speed with excellent quality*

## 🔥 News

- 2026.04.12: We are excited to release the [Wan2.2-I2V-A14B-4step-720p-high](https://huggingface.co/lightx2v/Wan2.2-Distill-Models/blob/main/wan2.2_i2v_A14b_high_noise_lightx2v_4step_720p_260412.safetensors) and [Wan2.2-I2V-A14B-4step-720p-low](https://huggingface.co/lightx2v/Wan2.2-Distill-Models/blob/main/wan2.2_i2v_A14b_low_noise_lightx2v_4step_720p_260412.safetensors) 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.

## 🚀 Quick Usage (Python)

To use these models with the [LightX2V](https://github.com/ModelTC/LightX2V) framework for 4-step inference:

```python
from lightx2v import LightX2VPipeline

# Initialize pipeline for Wan2.2 I2V task
pipe = LightX2VPipeline(
    model_path="lightx2v/Wan2.2-Distill-Models",
    model_cls="wan2.2_moe",
    task="i2v",
)

# Enable offloading to reduce VRAM usage
pipe.enable_offload(
    cpu_offload=True,
    offload_granularity="block",
    text_encoder_offload=True,
)

# Create generator for 4-step inference
pipe.create_generator(
    attn_mode="sage_attn2",
    infer_steps=4,
    height=480,
    width=832,
    num_frames=81,
    guidance_scale=[1.0, 1.0],
)

# Generate video
pipe.generate(
    seed=42,
    image_path="path/to/your/image.jpg",
    prompt="A cinematic shot of a sunset over the ocean",
    save_result_path="output.mp4",
)
```

## ⚠️ 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](https://lightx2v-zhcn.readthedocs.io/zh-cn/latest/getting_started/model_structure.html) for instructions on organizing the complete model directory.
