HiDream-I1

HiDream-I1 is a new open-source image generative foundation model with 17B parameters that achieves state-of-the-art image generation quality within seconds.

Project Updates

2025/4/7: We've open-sourced the text-to-image model HiDream-I1.

Models

We offer both the full version and distilled models. For more information about the models, please refer to the link under Usage.

Name	Script	Inference Steps	HuggingFace repo
HiDream-I1-Full	inference.py	50	🤗 HiDream-I1-Full
HiDream-I1-Dev	inference.py	28	🤗 HiDream-I1-Dev
HiDream-I1-Fast	inference.py	16	🤗 HiDream-I1-Fast

Quick Start

Please make sure you have installed Flash Attention. We recommend CUDA versions 12.4 for the manual installation.

pip install -r requirements.txt

Then you can run the inference scripts to generate images:

# For full model inference
python ./inference.py --model_type full

# For distilled dev model inference
python ./inference.py --model_type dev

# For distilled fast model inference
python ./inference.py --model_type fast

Note: The inference script will automatically download meta-llama/Meta-Llama-3.1-8B-Instruct model files. If you encounter network issues, you can download these files ahead of time and place them in the appropriate cache directory to avoid download failures during inference.

Gradio Demo

We also provide a Gradio demo for interactive image generation. You can run the demo with:

python gradio_demo.py
