# Hunyuan-DiT : A Powerful Multi-Resolution Diffusion Transformer with Fine-Grained Chinese Understanding
# 混元-DiT: 具有细粒度中文理解的多分辨率Diffusion Transformer

[[Arxiv]](https://arxiv.org/abs/2405.08748) [[project page]](https://dit.hunyuan.tencent.com/) [[github]](https://github.com/Tencent/HunyuanDiT)

This repo contains the distilled Hunyuan-DiT in 🤗 [Diffusers](https://github.com/huggingface/diffusers) format.

It supports 25-step text-to-image generation.

## Dependency
Please install PyTorch first, following the instruction in [https://pytorch.org](https://pytorch.org)

Install the latest version of transformers with `pip`:
```
pip install --upgrade transformers
```

Then install the latest github version of 🤗 Diffusers with `pip`:
```
pip install git+https://github.com/huggingface/diffusers.git
```

## Example Usage with 🤗 Diffusers
```py
import torch
from diffusers import HunyuanDiTPipeline

pipe = HunyuanDiTPipeline.from_pretrained("Tencent-Hunyuan/HunyuanDiT-Diffusers-Distilled", torch_dtype=torch.float16)
pipe.to("cuda")

# You may also use English prompt as HunyuanDiT supports both English and Chinese
# prompt = "An astronaut riding a horse"
prompt = "一个宇航员在骑马"
image = pipe(prompt).images[0]
```

## 📈 Comparisons
In order to comprehensively compare the generation capabilities of HunyuanDiT and other models, we constructed a 4-dimensional test set, including Text-Image Consistency, Excluding AI Artifacts, Subject Clarity, Aesthetic. More than 50 professional evaluators performs the evaluation.
