Usage

Loading the Model

This is a PEFT adapter that must be loaded on top of the base model:

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
import torch

# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
    "Qwen/Qwen2.5-Coder-7B-Instruct",
    device_map="auto",
    trust_remote_code=True,
    torch_dtype=torch.bfloat16
)

# Load MUMPS adapter
model = PeftModel.from_pretrained(
    base_model,
    "YanivWeiss123/Qwen2.5-Coder-7B-Instruct-MUMPS"
)

tokenizer = AutoTokenizer.from_pretrained(
    "YanivWeiss123/Qwen2.5-Coder-7B-Instruct-MUMPS",
    trust_remote_code=True
)

Inference Example

# Generate MUMPS code
prompt = "Write a MUMPS routine to register a new patient with name, DOB, and SSN"

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=200, temperature=0.7)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)

print(response)

Example Prompts

"Write a MUMPS routine to register a new patient"
"Create a MUMPS function to calculate age from date of birth"
"How do I use $ORDER to iterate through a global array?"
"Explain what this MUMPS code does: SET x=$PIECE(data,'^',3)"
"Write MUMPS code to retrieve all medications for a patient"
"Refactor this MUMPS routine for better error handling"

Capabilities

What the Model Can Do

✅ Generate MUMPS code from natural language descriptions ✅ Explain MUMPS syntax, functions, and commands ✅ Answer questions about MUMPS programming patterns ✅ Handle healthcare/EHR-specific scenarios (patient records, medications, etc.) ✅ Work with MUMPS globals, functions, and special variables ✅ Generate complete routines with proper structure ✅ Provide code examples with comments

Limitations

❌ Not trained on specific VistA/Epic/Cerner codebase internals ❌ May not know organization-specific global naming conventions ❌ Limited knowledge of proprietary MUMPS extensions ❌ General LLM limitations (hallucination, context length, etc.) ❌ Should not be used for production medical systems without review
