Adapting Multimodal Large Language Models to Domains via Post-Training (EMNLP 2025)

This repos contains the food MLLM developed from Llama-3.2-11B-Vision-Instruct in our paper: On Domain-Specific Post-Training for Multimodal Large Language Models.

The main project page is: Adapt-MLLM-to-Domains

1. To Chat with AdaMLLM

Our model architecture aligns with the base model: Llama-3.2-Vision-Instruct. We provide a usage example below, and you may refer to the official Llama-3.2-Vision-Instruct Repository for more advanced usage instructions.

Note: For AdaMLLM, always place the image at the beginning of the input instruction in the messages.

Starting with transformers >= 4.45.0 onward, you can run inference using conversational messages that may include an image you can query about.

Make sure to update your transformers installation via pip install --upgrade transformers.

2. To Evaluate Any MLLM on Domain-Specific Benchmarks

Refer to the food-VQA-benchmark to reproduce our results and evaluate many other MLLMs on domain-specific benchmarks.

3. To Reproduce this Domain-Adapted MLLM

See Post-Train Guide to adapt MLLMs to domains.
