Build a local RAG system on a mini PC with open-source tools

By PulseAugur Editorial · [1 sources] ·

A guide details how to set up a local Retrieval-Augmented Generation (RAG) system on a mini PC using open-source tools. The setup involves using EmbeddingGemma 2, a 740M-parameter embedding model from Google/Deepmind, and PDF Desk, a Python application for querying PDFs. The guide emphasizes that vector stores like Qdrant or Chroma are optional for initial setup, focusing on getting a basic pipeline running first. It provides step-by-step instructions for downloading the model, running the PDF Desk application, and discusses potential issues such as RAM limitations and the single-document constraint of PDF Desk.

    Local RAG on a mini PC: EmbeddingGemma 2, PDF Desk, and when to add a vector store

    <p>Local RAG doesn't require a GPU tower humming under your desk. On a mini PC you can assemble a working retrieval pipeline from two published pieces: EmbeddingGemma 2, an open 740M-parameter embedding model, and PDF Desk, a small Python/Streamlit app that answers questions abou…
