MedGemma 1.5 GGUF (Optimized for Intel Mac & Metal)

Project Overview

This model is a quantized version of MedGemma 1.5, developed as a core component of the MedGemma Local Triage system for the Kaggle MedGemma Impact Challenge.

The primary goal is to provide a high-performance, 100% offline clinical decision support tool capable of running on consumer-grade hardware (specifically Intel-based Macs) in infrastructure-less environments.

Quantization Details

• Method: Quantized using llama.cpp
• Format: GGUF
• Quantization Level: Q4_K_M (Optimal balance between clinical accuracy and memory efficiency)
• Target Hardware: Intel Mac with 16GB+ RAM and AMD GPU (Metal enabled)

Performance on Edge Hardware

In our local tests on an Intel Mac (i9/AMD Radeon Pro 5500M 4GB):

• Inference Speed: ~15 tokens/sec
• Reasoning Latency: Sub-second response for clinical triage logic.
• Memory Footprint: Fits comfortably within 16GB RAM constraints.

Intended Use

• Clinical Triage Assistance: Helping frontline workers prioritize patients based on MSF and US Army protocols.
• Offline Medical RAG: Serving as the reasoning engine for local vector databases (ChromaDB).
• Privacy-First Applications: Scenarios where patient data residency is strictly local.

How to Use

1. Download the .gguf file.
2. Use with llama.cpp or any GGUF-compatible runner.
3. For Metal acceleration on Mac:

   ./llama-cli -m medgemma-1.5-q4_k_m.gguf -ngl 99 --color -p "Patient presents with..."
