🧠 MedScholar-1.5B

MedScholar-1.5B is a compact, instruction-aligned medical question-answering model fine-tuned on 1 million randomly selected examples from the MIRIAD-4.4M dataset. It is based on the Qwen/Qwen2.5-1.5B-Instruct model and designed for efficient, in-context clinical knowledge exploration — not diagnosis.

📌 Model Details

• Base Model: Qwen2.5-1.5B-Instruct-unsloth-bnb-4bit
• Fine-tuning Dataset: MIRIAD-4.4M
• Samples Used: 1,000,000 examples randomly selected from the full set
• Prompt Style: Minimal QA format (see below)
• Training Framework: Unsloth with QLoRA
• License: Apache-2.0 (inherits from base model); dataset is ODC-By 1.0

---

📋 Prompt Format

### Question:
What is the role of LDL in cardiovascular health?

### Answer:
LDL plays a central role in the development of atherosclerosis by delivering cholesterol to peripheral tissues...

• The model expects the prompt to end with ### Answer:, and will generate only the answer text.
• Do not include the answer in the prompt during inference.

💡 Example Inference (Python)

from transformers import pipeline

pipe = pipeline("text-generation", model="yasserrmd/MedScholar-1.5B", device=0)

prompt = """### Question:
What are the symptoms of acute pancreatitis?

### Answer:
"""

response = pipe(prompt, max_new_tokens=256, do_sample=True, temperature=0.7)
print(response[0]["generated_text"])
