🍎 Your Health Data Stays Local: Building a Private RAG with Llama 3, MLX, and Apple Silicon

When it comes to personal data, nothing is intimate than your Apple Health records. We're talking about heart rate variability, sleep cycles, and blood glucose levels. While the cloud is convenient, uploading your entire medical history to a third-party LLM provider is a privacy nightmare. In this tutorial, we are building a Local-First Retrieval-Augmented Generation (RAG) system. We will leverage Llama 3, optimized via the MLX framework for Apple Silicon, to chat with your export.xml file. No data leaves your machine. No API keys are required. Just raw local power.
