About

Hi I'm Cole Medin and I'm your guy for learning how to make a huge impact with AI agents and AI coding assistants. AI is no doubt the future of not just software development but the whole world. And I'm on a mission to master it and share everything with you. Join me as I push the limits of what is possible with AI. I'll be uploading videos weekly - at least every Wednesday at 7:00 PM CDT!

Video Description

Providing our AI Agents with external knowledge through RAG is crucial for a majority of AI applications. But generally, a basic RAG implementation is only going to be 50-75% accurate when retrieving the correct information from your knowledgebase. If you want to build real AI solutions, that just won’t cut it. I've been researching all the best strategies for making RAG more accurate (and scalable for millions of documents), and enhancing RAG with knowledge graphs has really stuck out to me, specifically using an incredible open source library called LightRAG. LightRAG not only vectorizes your documents like traditional RAG, it also builds up a knowledge graph that connects concepts, entities, and ideas together to take the contextual understanding of your AI agent to a new dimension. In this video, we'll build a LightRAG implementation that you can use as a starting point to build some VERY powerful RAG AI agents. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Check out Graphiti (free & open source) if you want to build RAG applications that work with real-time data: https://github.com/getzep/graphiti ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ LightRAG GitHub repo: https://github.com/HKUDS/LightRAG Link to my LightRAG implementation (with the ChromaDB version too): https://github.com/coleam00/ottomator-agents/tree/main/light-rag-agent ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 00:00 - Introducing LightRAG - Accurate & Scalable RAG 02:02 - LightRAG Overview & GitHub Repo 05:07 - LightRAG vs. "Traditional" RAG & GraphRAG 05:53 - Get Started with LightRAG in 2 Minutes 07:44 - Our LightRAG AI Agent 09:27 - Graphiti - Real-Time Knowledge Graphs 10:54 - Testing Our LightRAG vs ChromaDB AI Agents 13:29 - Building Our LightRAG Knowledge Graph 16:48 - LightRAG AI Agent Code Deep Dive 20:09 - Covering the ChromaDB "Traditional" RAG Agent 21:36 - Final Thoughts 22:34 - Outro ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Join me as I push the limits of what is possible with AI.
