# LiFT: Leveraging Human Feedback for Text-to-Video Model Alignment


## Summary
This is the model checkpoint proposed in our paper "LiFT: Leveraging Human Feedback for Text-to-Video Model Alignment". LiFT-Critic is a novel Video-Text-to-Text Reward Model for synthesized video evaluation.

Project: https://codegoat24.github.io/LiFT/

Code: https://github.com/CodeGoat24/LiFT

## 🔧 Installation

1. Clone the github repository and navigate to LiFT folder
```bash
git clone https://github.com/CodeGoat24/LiFT.git
cd LiFT
```
2. Install packages
```
bash ./environment_setup.sh lift
```

## 🚀 Inference

### Run
Please download this public [LiFT-Critic-40b-lora-v1.5](https://huggingface.co/Fudan-FUXI/LiFT-Critic-13b-lora-v1.5) checkpoints. 

We provide some synthesized videos for quick inference in `./demo` directory.

```bash
python LiFT-Critic/test/run_critic_40b.py --model-path ./LiFT-Critic-40b-lora-v1.5
```
