**HealthGPT Series** is a medical multimodal large language model (MLLM) family composed of two subrepositories:
- [**HealthGPT-Pro**](./HealthGPT-Pro/README.md): a high-performance MLLM for **medical understanding and analysis**, supporting medical **text**, **2D images**, and **3D volumes**.
- [**HealthGPT**](./HealthGPT/README.md): a unified MLLM for **medical comprehension and generation**, built around heterogeneous knowledge adaptation.
Together, the series covers both:
- a **strong unified generation + comprehension framework** in HealthGPT, and
- a **new flagship understanding model** in HealthGPT-Pro with broader modality support and stronger benchmark performance.
### π From HealthGPT to HealthGPT-Pro
Compared with **HealthGPT**, **HealthGPT-Pro** substantially advances medical understanding capabilities:
| Aspect | HealthGPT | HealthGPT-Pro |
| --- | --- | --- |
| **Supported modalities** | 8 modalities | 14 modalities |
| **Training data scale** | ~1.5M samples | ~13M samples |
| **Capability scope** | Medical images | Medical text, 2D medical images, and 3D medical volumes |
| **Benchmark standing** | Strong unified medical LVLM | State-of-the-art medical understanding performance |
This makes **HealthGPT-Pro** a significant upgrade for medical understanding tasks while **HealthGPT** remains the foundation for unified medical comprehension and generation research.

## π Overview
Welcome to **HealthGPT!** π©Ί
**HealthGPT** is an advanced medical Large Vision-Language Model with a unified framework that integrates both medical visual comprehension and generation capabilities. In this project, a **heterogeneous low rank adaptation (H-LoRA)** and a **three-stage learning strategy** are proposed, enabling the pre-trained large language model to efficiently follow both visual comprehension and generation instructions.
## π Task Classification and Support
**HealthGPT** supports **7** types of medical comprehension tasks and **5** types of medical generation tasks, outperforming recent unified visual models and medical-specific models.
### ποΈ Architecture
The HealthGPT architecture integrates **hierarchical visual perception** and **H-LoRA**, employing a task-specific hard router to select visual features and H-LoRA plugins, generating text and vision outputs with an autoregressive manner.
For complete model details, setup, and inference instructions, please refer to [HealthGPT/README.md](./HealthGPT/README.md).
