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

RAG is the go-to solution for giving AI agents access to your knowledge base, but traditional RAG has major limitations - it misses context by splitting key ideas/concepts, can't connect information across documents, and lacks dynamic analysis capabilities. This ultimate n8n RAG template solves these issues using three key strategies: - Agentic RAG - Gives the agent intelligence to reason about how to explore your knowledge base (view full documents, semantic search, or query structured data based on the specific question) - Reranking - Expands initial search results then uses a specialized model to return only the most relevant information - Agentic Chunking - Uses an LLM to intelligently determine document split boundaries, preserving important context that traditional chunking destroys The result is a RAG agent that actually works the way you'd want it to - understanding your documents holistically, connecting related information, and giving you the comprehensive answers you're looking for. ~~~~~~~~~~~~~~~~~~~~~~~~~ - Try Depot today for blazing fast cloud infrastructure for application builds: https://fandf.co/4247Qys - Give the remote agent sandboxes a try for free: https://depot.dev/docs/agents/claude-code/quickstart ~~~~~~~~~~~~~~~~~~~~~~~~~ - If you're looking to join a community for early AI adopters to master AI Agents & RAG and transform your career or business, check out Dynamous: https://dynamous.ai - Neon (serverless Postgres I used in this video): https://get.neon.com/NsowhUM - Newest n8n RAG AI Agent Template: https://github.com/coleam00/ottomator-agents/tree/main/ultimate-n8n-rag-agent NOTE: The Langchain code node used in this template is only available when you self-host n8n.
