Llama3.2-Medical-Notes-1B-ONNX

This is the ONNX quantized version of the Llama3.2-Medical-Notes-1B model, optimized for efficient inference and deployment.

Model Details

Base Model: meta-llama/Llama-3.2-1B-Instruct
Fine-tuning Method: PEFT (Parameter-Efficient Fine-Tuning) using LoRA
Training Framework: Unsloth library for accelerated fine-tuning and merging
Quantization: ONNX format for optimized inference
Task: Text Generation (specifically, generating structured SOAP notes)

Paper

Intended Use

Input: Free-text medical transcripts (doctor-patient conversations or dictated notes).

Output: Structured medical notes with clearly defined sections (Demographics, Presenting Illness, History, etc.).

Usage with ONNX Runtime

import onnxruntime as ort
from transformers import AutoTokenizer
import numpy as np

# Load the ONNX model
model_name = "GetSoloTech/Llama3.2-Medical-Notes-1B-ONNX"
tokenizer = AutoTokenizer.from_pretrained("GetSoloTech/Llama3.2-Medical-Notes-1B")

# Initialize ONNX Runtime session
session = ort.InferenceSession(onnx_file_path)

SYSTEM_PROMPT = """Convert the following medical transcript to a structured medical note.

Use these sections in this order:

1. Demographics
   - Name, Age, Sex, DOB

2. Presenting Illness
   - Bullet point statements of the main problem and duration.

3. History of Presenting Illness
   - Chronological narrative: symptom onset, progression, modifiers, associated factors.

4. Past Medical History
   - List chronic illnesses and past medical diagnoses mentioned in the transcript. Do not include surgeries.

5. Surgical History
   - List prior surgeries with year if known, as mentioned in the transcript.

6. Family History
   - Relevant family history mentioned in the transcript.

7. Social History
   - Occupation, tobacco/alcohol/drug use, exercise, living situation if mentioned in the transcript.

8. Allergy History
   - Drug, food, or environmental allergies and reactions, if mentioned in the transcript.

9. Medication History
   - List medications the patient is already taking. Do not include any new or proposed drugs in this section.

10. Dietary History
    - If unrelated, write "Not applicable"; otherwise, summarize the diet pattern.

11. Review of Systems
    - Head-to-toe, alphabetically ordered bullet points; include both positives and pertinent negatives as mentioned in the transcript.

12. Physical Exam Findings
    - Vital Signs (BP, HR, RR, Temp, SpO₂, HT, WT, BMI) if mentioned in the transcript.
    - Structured by system: General, HEENT, Cardiovascular, Respiratory, Abdomen, Neurological, Musculoskeletal, Skin, Psychiatric—as mentioned in the transcript.

13. Labs and Imaging
    - Summarize labs and imaging results.

14. ASSESSMENT
    - Provide a brief summary of the clinical assessment or diagnosis based on the information in the transcript.

15. PLAN
    - Outline the proposed management plan, including treatments, medications, follow-up, and patient instructions as discussed.

Please use only the information present in the transcript. If an information is not mentioned or not applicable, state "Not applicable." Format each section clearly with its heading.

Alternative Usage with Transformers (Original Model)

If you prefer to use the original model instead of the ONNX version:

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "GetSoloTech/Llama3.2-Medical-Notes-1B"  
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name, device_map="auto")

def generate_structured_note(transcript):
    message = [
        {"role": "system", "content": SYSTEM_PROMPT},
        {"role": "user", "content": f"<START_TRANSCRIPT>\n{transcript}\n<END_TRANSCRIPT>\n"},
    ]

    inputs = tokenizer.apply_chat_template(
        message,
        tokenize=True,
        add_generation_prompt=True,
        return_tensors="pt",
    ).to(model.device)

    outputs = model.generate(
        input_ids=inputs,
        max_new_tokens=2048,
        temperature=0.2,
        top_p=0.85,
        min_p=0.1,
        top_k=20,
        do_sample=True,
        eos_token_id=tokenizer.eos_token_id,
        use_cache=True,
    )

    input_token_len = len(inputs[0])
    generated_tokens = outputs[:, input_token_len:]
    note = tokenizer.batch_decode(generated_tokens, skip_special_tokens=True)[0]
    if "<START_NOTES>" in note:
       note = note.split("<START_NOTES>")[-1].strip()
    if "<END_NOTES>" in note:
       note = note.split("<END_NOTES>")[0].strip()
    return note
