MadriMed 1.2
2B Multimodal Medical Vision-Language Model
---
## Overview
**MadriMed 1.2** is the second compact multimodal medical vision-language model by Madrisight. Building upon [madriMed-VL-2B](https://huggingface.co/madrisight/madriMed-VL-2B), MadriMed 1.2 delivers significant performance leaps across medical image understanding (Radiology, Pathology, CT, MRI, X-Ray) and medical reasoning.
It Delivers robust clinical reasoning capabilities, drastically reducing hallucinations and diagnostic contradictions while setting a new state-of-the-art benchmark for 2B medical vision models.
## What's New in MadriMed 1.2?
1. **Massive Diagnostic Accuracy Gains**:
- Massive jump on VQA-RAD overall score and most of the other evalution benchmarks.
2. **Resistant to Generation Hallucinations**:
- Substantially reduced token corruption, repetition and positive-bias tendencies observed in version one.
3. **Structured Formating**:
- Trained with graduated correctness scoring and reasoning-integrity penalties to enforce structured.

## Quick Start
### Installation
```bash
pip install torch torchvision transformers
```
### Input
```python
prompt = """Question: Examine the mammogram image shown above. Which of the following findings is most evident?
Answer Choices:
A. Well-circumscribed round mass with benign features
B. Clustered microcalcifications within an area of irregular density
C. Fat-containing lesion consistent with lipoma
D. Diffuse bilateral breast edema
Follow this exact step-by-step reasoning structure.
### 1. Key Clinical Findings
Extract the patient's age, gender, main symptoms, duration, objective physical exam findings, and abnormal laboratory/imaging results from the provided question and the images.
### 2. Differential Diagnosis
List 2-3 highly probable conditions based on the extracted findings. Briefly state why the current presentation fits.
### 3. Option Elimination
Analyze each provided choice. Write one sentence explaining why it is either correct or incorrect based on clinical guidelines.
### 4. Conclusion & Final Answer
State the final diagnostic/management conclusion.
### 5. Final correct choice
Provide final single correct choice.

### Run the model directly
```python
import torch
from transformers import AutoProcessor, Qwen3VLForConditionalGeneration
from PIL import Image
MODEL_ID = "madrisight/madrimed1.2-VL-2B"
device = "mps" if torch.backends.mps.is_available() else "cpu"
model = Qwen3VLForConditionalGeneration.from_pretrained(
MODEL_ID,
device_map=device,
dtype=torch.float32,
trust_remote_code=True,
).eval()
processor = AutoProcessor.from_pretrained(MODEL_ID, trust_remote_code=True)
# Multi-image input
image_paths = ["images/MM-1-a.png", "images/MM-1-b.png"]
images = [Image.open(path).convert("RGB") for path in image_paths]
# Chat Message Payload
messages = [
{
"role": "system",
"content": "You are an expert clinical medical educator and USMLE board reviewer.",
},
{
"role": "user",
"content": [{"type": "image"} for _ in images] + [{"type": "text", "text": prompt}]
}
]
# Tokenize, Process, and Generate
with torch.inference_mode():
text = processor.apply_chat_template(
messages,
tokenize=False,
add_generation_prompt=True
)
inputs = processor(
text=text,
images=images, # Pass the flat list of PIL Image objects
return_tensors="pt",
padding=True,
truncation=True,
).to(device)
generated_ids = model.generate(
**inputs,
max_new_tokens=1024,
do_sample=False,
)
output_text = processor.batch_decode(
generated_ids[:, inputs.input_ids.shape[1]:],
skip_special_tokens=True
)[0].strip()
```
### Output
```plaintext
### 1. Key Clinical Findings
- **Patient's age and gender**: Not explicitly mentioned, but mammograms are typically used for women.
- **Main symptoms**: Not specified, but mammograms are often performed for breast abnormalities.
- **Duration**: Not specified, but mammograms are usually performed at the time of suspicion.
- **Objective physical exam findings**: Not specified, but mammograms are used to detect abnormalities.
- **Abnormal laboratory/imaging results**: Not specified, but mammograms are used to detect breast abnormalities.
### 2. Differential Diagnosis
- **Well-circumscribed round mass with benign features**: This could be a benign lesion such as a fibroadenoma.
- **Clustered microcalcifications within an area of irregular density**: This could indicate a malignant process, such as ductal carcinoma in situ (DCIS) or invasive breast cancer.
- **Fat-containing lesion consistent with lipoma**: This is a benign lesion and could be a lipoma.
### 3. Option Elimination
- **Well-circumscribed round mass with benign features**: This is a plausible finding, but it is less likely to be the primary concern in a mammogram without additional symptoms or findings.
- **Clustered microcalcifications within an area of irregular density**: This is a highly suspicious finding for malignancy, as it is often associated with breast cancer.
- **Fat-containing lesion consistent with lipoma**: This is a benign finding and less likely to be the primary concern in a mammogram without additional symptoms or findings.
### 4. Conclusion & Final Answer
The mammogram findings are most indicative of a malignant process, specifically breast cancer, due to the presence of clustered microcalcifications within an area of irregular density.
### 5. Final correct choice
B. Clustered microcalcifications within an area of irregular density

## Limitations & Safety Guidelines
> **Research & Educational Use Only**
MadriMed 1.2 is an **experimental research model**. It is not certified for autonomous clinical diagnostic decision-making.
### No Treatment Prescriptions
The model should **not** be used as an authoritative source for:
- Pharmaceutical dosages
- Surgical interventions
- Direct treatment pathways
- Other high-stakes clinical decisions
All model-generated interpretations, medical reasoning, and visual inferences should be **reviewed and independently confirmed by a qualified, licensed medical professional** before being used in a clinical context.
