ImageBind-LLM: Multi-modality Instruction Tuning

Han, Jiaming, Zhang, Renrui, Shao, Wenqi et al.

Understand

We present ImageBind-LLM, a multi-modality instruction tuning method of large language models (LLMs) via ImageBind.

  • Existing works mainly focus on language and image instruction tuning, different from which, our ImageBind-LLM can respond to multi-modality conditions, including audio, 3D point clouds, video, and their embedding-space arithmetic by only image-text alignment training.
  • During training, we adopt a learnable bind network to align the embedding space between LLaMA and ImageBind's image encoder.
  • Then, the image features transformed by the bind network are added to word tokens of all layers in LLaMA, which progressively injects visual instructions via an attention-free and zero-initialized gating mechanism.
