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.

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.

   # 1 Install dependencies
   cd HunyuanDiT
   pip install -e ./IndexKits
   

2. Data download

   Feel free to download the data demo.

   # 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 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.

   # 3 Data conversion 
   python ./hydit/data_loader/csv2arrow.py ./dataset/porcelain/csvfile/image_text.csv ./dataset/porcelain/arrows 1
   

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 ./IndexKits.

   For a sample file, please refer to file. For a full parameter configuration file, see file.

5. Create training data index file using YAML file.

    # 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:

 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)

    │  ├──porcelain.json
    │  ├──porcelain_mt.json

Full-parameter Training

Requirement:

1. The minimum requriment is a single GPU with at least 20GB memory, but we recommend to use a GPU with about 30 GB memory to avoid host memory offloading.
2. Additionally, we encourage users to leverage the multiple GPUs across different nodes to speed up training on large datasets.

Notice:

1. Personal users can also use the light-weight Kohya to finetune the model with about 16 GB memory. Currently, we are trying to further reduce the memory usage of our industry-level framework for personal users.
2. If you have enough GPU memory, please try to remove --cpu-offloading or --gradient-checkpointing for less time costs.

Specifically for distributed 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.

b. Model download

# Use the huggingface-cli tool to download the model.
huggingface-cli download Tencent-Hunyuan/HunyuanCaptioner --local-dir ./ckpts/captioner

Inference

Our model supports three different modes including: directly generating Chinese caption, generating Chinese caption based on specific knowledge, and directly generating English caption. The injected information can be either accurate cues or noisy labels (e.g., raw descriptions crawled from the internet). The model is capable of generating reliable and accurate descriptions based on both the inserted information and the image content.

a. Single picture inference in Chinese

python mllm/caption_demo.py --mode "caption_zh" --image_file "mllm/images/demo1.png" --model_path "./ckpts/captioner"

b. Insert specific knowledge into caption

python mllm/caption_demo.py --mode "insert_content" --content "宫保鸡丁" --image_file "mllm/images/demo2.png" --model_path "./ckpts/captioner"

c. Single picture inference in English

python mllm/caption_demo.py --mode "caption_en" --image_file "mllm/images/demo3.png" --model_path "./ckpts/captioner"

d. Multiple pictures inference in Chinese

### Convert multiple pictures to csv file. 
python mllm/make_csv.py --img_dir "mllm/images" --input_file "mllm/images/demo.csv"

### Multiple pictures inference
python mllm/caption_demo.py --mode "caption_zh" --input_file "mllm/images/demo.csv" --output_file "mllm/images/demo_res.csv" --model_path "./ckpts/captioner"

(Optional) To convert the output csv file to Arrow format, please refer to Data Preparation #3 for detailed instructions.

Gradio

To launch a Gradio demo locally, please run the following commands one by one. For more detailed instructions, please refer to LLaVA.

cd mllm
python -m llava.serve.controller --host 0.0.0.0 --port 10000

python -m llava.serve.gradio_web_server --controller http://0.0.0.0:10000 --model-list-mode reload --port 443

python -m llava.serve.model_worker --host 0.0.0.0 --controller http://0.0.0.0:10000 --port 40000 --worker http://0.0.0.0:40000 --model-path "../ckpts/captioner" --model-name LlavaMistral

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.

🚀 Acceleration (for Linux)

• We provide TensorRT version of HunyuanDiT for inference acceleration (faster than flash attention). See Tencent-Hunyuan/TensorRT-libs for more details.

• We provide Distillation version of HunyuanDiT for inference acceleration. See Tencent-Hunyuan/Distillation for more details.
