## ✨ Features

- **⚡ 4-Step Inference**: Dramatically accelerated end-to-end generation approaching real-time performance (tested on RTX 5090 single GPU)
- **🎯 NVFP4 Quantization**: Reduced memory and bandwidth usage, optimized for Blackwell architecture
- **🔧 LightX2V Integration**: Optimal performance and stability on the official framework
- **🚀 High-Quality Generation**: Maintains Self-Forcing's superior video quality while achieving unprecedented speed

## 🚀 Quick Start

```bash
# 1. Install LightX2V
git clone https://github.com/ModelTC/LightX2V.git
cd LightX2V
uv pip install -v .

# 2. Install NVFP4 Kernel
pip install scikit_build_core uv
git clone https://github.com/NVIDIA/cutlass.git
cd lightx2v_kernel

MAX_JOBS=$(nproc) CMAKE_BUILD_PARALLEL_LEVEL=$(nproc) \
uv build --wheel \
  -Cbuild-dir=build . \
  -Ccmake.define.CUTLASS_PATH=/path/to/cutlass \
  --verbose --color=always --no-build-isolation

pip install dist/*whl --force-reinstall --no-deps

# 3. Run inference
# config

## ⚠️ Notes

### System Requirements
- **Required Hardware**: NVIDIA RTX 50-series GPUs (RTX 5090/5080/5070/5060) or other Blackwell architecture GPUs

### Dependencies
- Prepare T5 / CLIP / VAE components yourself (same as Self-Forcing structure)

### Performance Tips
- Use Blackwell + NVFP4 for best performance
- Enable CPU offload for GPUs with limited memory
