• DiffBlender successfully synthesizes complex combinations of input modalities. It enables flexible manipulation of conditions, providing the customized generation aligned with user preferences.
• We designed its structure to intuitively extend to additional modalities while achieving a low training cost through a partial update of hypernetworks.

🗓️ TODOs

• Project page is open: link
• DiffBlender model: code & checkpoint
• Release inference code
• Release training code & pipeline
• Gradio UI

🚀 Getting Started

Install the necessary packages with:

$ pip install -r requirements.txt

Download DiffBlender model checkpoint from this Huggingface model, and place it under ./diffblender_checkpoints/.
Also, prepare the SD model from this link (we used CompVis/sd-v1-4.ckpt).

⚡️ Try Multimodal T2I Generation with DiffBlender

$ python inference.py --ckpt_path=./diffblender_checkpoints/{CKPT_NAME}.pth \
                      --official_ckpt_path=/path/to/sd-v1-4.ckpt \
                      --save_name={SAVE_NAME} 

Results will be saved under ./inference/{SAVE_NAME}/, in the format as {conditions + generated image}.
