## Introduction

We release the adaptation models for the specific domains: autonomous driving, medical images, and remote sensing.

These models are built upon Mini-InternVL and fine-tuned using a unified adaptation framework, achieving good performance on tasks in specific domains.

## Quick Start

We provide an example code to run `Mini-InternVL2-1B` using `transformers`.

> Please use transformers>=4.37.2 to ensure the model works normally.
