## **Abstract**

We present Hunyuan-DiT, a text-to-image diffusion transformer with fine-grained understanding of both English and Chinese. To construct Hunyuan-DiT, we carefully designed the transformer structure, text encoder, and positional encoding. We also build from scratch a whole data pipeline to update and evaluate data for iterative model optimization. For fine-grained language understanding, we train a Multimodal Large Language Model to refine the captions of the images. Finally, Hunyuan-DiT can perform multi-round multi-modal dialogue with users, generating and refining images according to the context.
Through our carefully designed holistic human evaluation protocol with more than 50 professional human evaluators, Hunyuan-DiT sets a new state-of-the-art in Chinese-to-image generation compared with other open-source models.


## 🎉 **Hunyuan-DiT Key Features**
### **Chinese-English Bilingual DiT Architecture**
Hunyuan-DiT is a diffusion model in the latent space, as depicted in figure below. Following the Latent Diffusion Model, we use a pre-trained Variational Autoencoder (VAE) to compress the images into low-dimensional latent spaces and train a diffusion model to learn the data distribution with diffusion models. Our diffusion model is parameterized with a transformer. To encode the text prompts, we leverage a combination of pre-trained bilingual (English and Chinese) CLIP and multilingual T5 encoder.

### Multi-turn Text2Image Generation
Understanding natural language instructions and performing multi-turn interaction with users are important for a
text-to-image system. It can help build a dynamic and iterative creation process that bring the user’s idea into reality
step by step. In this section, we will detail how we empower Hunyuan-DiT with the ability to perform multi-round
conversations and image generation. We train MLLM to understand the multi-round user dialogue
and output the new text prompt for image generation.

## 📈 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.

## :truck: Training

### Data Preparation

  Refer to the commands below to prepare the training data. 
  
  1. Install dependencies
  
      We offer an efficient data management library, named IndexKits, supporting the management of reading hundreds of millions of data during training, see more in [docs](https://github.com/Tencent/HunyuanDiT/blob/main/IndexKits/README.md).
      ```shell
      # 1 Install dependencies
      cd HunyuanDiT
      pip install -e ./IndexKits
     ```
  2. Data download 
  
     Feel free to download the [data demo](https://dit.hunyuan.tencent.com/download/HunyuanDiT/data_demo.zip).
     ```shell
     # 2 Data download
     wget -O ./dataset/data_demo.zip https://dit.hunyuan.tencent.com/download/HunyuanDiT/data_demo.zip
     unzip ./dataset/data_demo.zip -d ./dataset
     mkdir ./dataset/porcelain/arrows ./dataset/porcelain/jsons
     ```
  3. Data conversion 
  
     Create a CSV file for training data with the fields listed in the table below.
    
     |    Fields       | Required  |  Description     |   Example   |
     |:---------------:| :------:  |:----------------:|:-----------:|
     |   `image_path`  | Required  |  image path               |     `./dataset/porcelain/images/0.png`        | 
     |   `text_zh`     | Required  |    text               |  青花瓷风格，一只蓝色的鸟儿站在蓝色的花瓶上，周围点缀着白色花朵，背景是白色 | 
     |   `md5`         | Optional  |    image md5 (Message Digest Algorithm 5)  |    `d41d8cd98f00b204e9800998ecf8427e`         | 
     |   `width`       | Optional  |    image width    |     `1024 `       | 
     |   `height`      | Optional  |    image height   |    ` 1024 `       | 
     
     > ⚠️ Optional fields like MD5, width, and height can be omitted. If omitted, the script below will automatically calculate them. This process can be time-consuming when dealing with large-scale training data.
  
     We utilize [Arrow](https://github.com/apache/arrow) for training data format, offering a standard and efficient in-memory data representation. A conversion script is provided to transform CSV files into Arrow format.
     ```shell  
     # 3 Data conversion 
     python ./hydit/data_loader/csv2arrow.py ./dataset/porcelain/csvfile/image_text.csv ./dataset/porcelain/arrows
     ```
  
  4. Data Selection and Configuration File Creation 
     
      We configure the training data through YAML files. In these files, you can set up standard data processing strategies for filtering, copying, deduplicating, and more regarding the training data. For more details, see [docs](IndexKits/docs/MakeDataset.md).
  
      For a sample file, please refer to [file](https://github.com/Tencent/HunyuanDiT/blob/main/dataset/yamls/porcelain.yaml). For a full parameter configuration file, see [file](https://github.com/Tencent/HunyuanDiT/blob/main/IndexKits/docs/MakeDataset.md).
  
     
  5. Create training data index file using YAML file.
    
     ```shell
      # Single Resolution Data Preparation
      idk base -c dataset/yamls/porcelain.yaml -t dataset/porcelain/jsons/porcelain.json
   
      # Multi Resolution Data Preparation     
      idk multireso -c dataset/yamls/porcelain_mt.yaml -t dataset/porcelain/jsons/porcelain_mt.json
      ```
   
  The directory structure for `porcelain` dataset is:

  ```shell
   cd ./dataset
  
   porcelain
      ├──images/  (image files)
      │  ├──0.png
      │  ├──1.png
      │  ├──......
      ├──csvfile/  (csv files containing text-image pairs)
      │  ├──image_text.csv
      ├──arrows/  (arrow files containing all necessary training data)
      │  ├──00000.arrow
      │  ├──00001.arrow
      │  ├──......
      ├──jsons/  (final training data index files which read data from arrow files during training)
      │  ├──porcelain.json
      │  ├──porcelain_mt.json
   ```

### Full-parameter Training
 
  To leverage DeepSpeed in training, you have the flexibility to control **single-node** / **multi-node** training by adjusting parameters such as `--hostfile` and `--master_addr`. For more details, see [link](https://www.deepspeed.ai/getting-started/#resource-configuration-multi-node).

  ```shell
  # Single Resolution Data Preparation
  PYTHONPATH=./ sh hydit/train.sh --index-file dataset/porcelain/jsons/porcelain.json
  
  # Multi Resolution Data Preparation
  PYTHONPATH=./ sh hydit/train.sh --index-file dataset/porcelain/jsons/porcelain.json --multireso --reso-step 64
  ```

### LoRA

We provide training and inference scripts for LoRA, detailed in the [guidances](https://github.com/Tencent/HunyuanDiT/blob/main/lora/README.md). 


## 🔑 Inference

### Using Gradio

Make sure the conda environment is activated before running the following command.

```shell
# By default, we start a Chinese UI.
python app/hydit_app.py

# Using Flash Attention for acceleration.
python app/hydit_app.py --infer-mode fa

# You can disable the enhancement model if the GPU memory is insufficient.
# The enhancement will be unavailable until you restart the app without the `--no-enhance` flag. 
python app/hydit_app.py --no-enhance

# Start with English UI
python app/hydit_app.py --lang en

# Start a multi-turn T2I generation UI. 
# If your GPU memory is less than 32GB, use '--load-4bit' to enable 4-bit quantization, which requires at least 22GB of memory.
python app/multiTurnT2I_app.py
```
Then the demo can be accessed through http://0.0.0.0:443. It should be noted that the 0.0.0.0 here needs to be X.X.X.X with your server IP.

### Using 🤗 Diffusers

Please install PyTorch version 2.0 or higher in advance to satisfy the requirements of the specified version of the diffusers library.  

Install 🤗 diffusers, ensuring that the version is at least 0.28.1:

```shell
pip install git+https://github.com/huggingface/diffusers.git
```
or
```shell
pip install diffusers
```

You can generate images with both Chinese and English prompts using the following Python script:
```py
import torch
from diffusers import HunyuanDiTPipeline

pipe = HunyuanDiTPipeline.from_pretrained("Tencent-Hunyuan/HunyuanDiT-Diffusers", 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]
```
You can use our distilled model to generate images even faster:

```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, num_inference_steps=25).images[0]
```
More details can be found in [HunyuanDiT-Diffusers-Distilled](https://huggingface.co/Tencent-Hunyuan/HunyuanDiT-Diffusers-Distilled)

### Using Command Line

We provide several commands to quick start: 

```shell
# Prompt Enhancement + Text-to-Image. Torch mode
python sample_t2i.py --prompt "渔舟唱晚"

# Only Text-to-Image. Torch mode
python sample_t2i.py --prompt "渔舟唱晚" --no-enhance

# Only Text-to-Image. Flash Attention mode
python sample_t2i.py --infer-mode fa --prompt "渔舟唱晚"

# Generate an image with other image sizes.
python sample_t2i.py --prompt "渔舟唱晚" --image-size 1280 768

# Prompt Enhancement + Text-to-Image. DialogGen loads with 4-bit quantization, but it may loss performance.
python sample_t2i.py --prompt "渔舟唱晚"  --load-4bit

```

More example prompts can be found in [example_prompts.txt](example_prompts.txt)
