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.

For more features and to experience the full capabilities of our product, please visit https://vivago.ai/.

• 🤗 April 8, 2025: We've launched a Hugging Face Space for HiDream-I1-Dev. Experience our model firsthand at https://huggingface.co/spaces/HiDream-ai/HiDream-I1-Dev!
• 🚀 April 7, 2025: We've open-sourced the text-to-image model HiDream-I1.

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

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

pip install -r requirements.txt
pip install -U flash-attn --no-build-isolation

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

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

python gradio_demo.py
