Installation

Please follow LLaVA for setting up the training environment.

Model Weights

We list all the model and vision-text projector weights used in the paper

Evaluations

For NLP & Multi-Modal data and evaluations, please see instructions here.

Model Training

We follow the training paradigm of LLaVA, which consists of two stages: (1) feature alignment: use approximately 600K filtered CC3M to connect a frozen pretrained vision encoder to a frozen LLM; (2) visual instruction tuning: use filtered 80K GPT-generated visual instruction data (see here) to teach the model to follow multimodal instructions.

Feature Alignment Training

Please download the subset of the CC3M dataset we use in the paper here. You can check the pretraining script
