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] [project page] [github]

This repo contains the distilled Hunyuan-DiT in 🤗 Diffusers format.

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

Dependency

Please install PyTorch first, following the instruction in 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

import torch
from diffusers import HunyuanDiTPipeline

pipe = HunyuanDiTPipeline.from_pretrained("Tencent-Hunyuan/HunyuanDiT-v1.2-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.
