Welcome to the official repository of the Korean Medical Large Language Model (LLM) developed by the Healthcare AI Research Institute (HARI) at Seoul National University Hospital (SNUH).

🚀 Model Overview

Model Name: snuh/hari-q3
Architecture: Large Language Model (LLM)
Fine-tuning Objective: Medical QA (Question–Answer) style generation
Primary Language: English, Korean
Domain: Clinical Medicine
Performance: Achieves 84.14% accuracy on the Korean Medical Licensing Examination (KMLE)
Key Applications:
- Clinical decision support (QA-style)
- Medical education and self-assessment tools
- Automated medical reasoning and documentation aid

📊 Training Data & Benchmark

This model was fine-tuned using a curated corpus of Korean medical QA-style data derived from publicly available, de-identified sources. The training data includes clinical guidelines, academic publications, exam-style questions, and synthetic prompts reflecting real-world clinical reasoning.

Training Data Characteristics:
- Focused on Korean-language question–answering formats relevant to clinical settings.
- Includes guideline-derived questions, de-identified case descriptions, and physician-crafted synthetic queries.
- Designed to reflect realistic diagnostic, therapeutic, and decision-making scenarios.
Benchmark Evaluation:
- KMLE-style QA benchmark(KorMedMCQA)
- non-reasoning
  - Doctor: 70.57%
  - Nurse: 81.66%
  - Pharm: 76.61%
  - Dentist: 62.27%
- reasoning
  - Doctor: 84.14%
  - Nurse: 88.50%
  - Pharm: 85.42%
  - Dentist: 68.56%
- All evaluations were conducted on de-identified, non-clinical test sets, with no real patient data involved.

🤗 Model Usage Example

python

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

# Load tokenizer and model
model_name = "snuh/hari-q3-14b"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)

### Instruction:
당신은 임상 지식을 갖춘 유능하고 신뢰할 수 있는 한국어 기반 의료 어시스턴트입니다.
사용자의 질문에 대해 정확하고 신중한 임상 추론을 바탕으로 진단 가능성을 제시해 주세요.
반드시 환자의 연령, 증상, 검사 결과, 통증 부위 등 모든 단서를 종합적으로 고려하여 추론 과정과 진단명을 제시해야 합니다.
의학적으로 정확한 용어를 사용하되, 필요하다면 일반인이 이해하기 쉬운 용어도 병행해 설명해 주세요.

### Question:
60세 남성이 복통과 발열을 호소하며 내원하였습니다.
혈액 검사 결과 백혈구 수치가 상승했고, 우측 하복부 압통이 확인되었습니다.
가장 가능성이 높은 진단명은 무엇인가요?
