# Adapting Multimodal Large Language Models to Domains via Post-Training

This repository provides an implementation preview of our paper, **On Domain-Specific Post-Training for Multimodal Large Language Models**.

We investigate domain adaptation of MLLMs through post-training, focusing on data synthesis, training pipelines, and task evaluation. Our resulting model, **AdaMLLM**, consistently outperforms general MLLMs across various tasks in two domains: biomedicine and food.

- **1st Work: [AdaptLLM](https://huggingface.co/papers/2309.09530)**  
  We employ rule-based methods to extract tasks from domain-specific corpora, reformatting them into reading comprehension tasks for continued pre-training. Our 7B finance model outperforms domain-specific models of much larger scales, such as BloombergGPT-50B.

- **2nd Work: [Instruction Pretraining](https://huggingface.co/instruction-pretrain)**  
  We develop a general-purpose instruction synthesizer which significantly increases task diversity for LM pre-training, outperforming Vanilla Pretraining in both general pretraining from scratch and domain-adaptive continual pretraining.

- **3rd Work: AdaMLLM**  
  We extend supervised task synthesis to multimodality, introducing a unified **visual instruction synthesizer** to extract task pairs from image-caption data. Our synthetic tasks outperform those generated by manual rules, GPT-4, and GPT-4V in improving domain-specific performance for MLLMs.

Looking ahead, we aim to further broaden the scope of supervised task synthesis, efficiently enhancing the general capabilities of trained models.
