800+ Hours of Learning RAG + Agentic Design in 42 mins (n8n Masterclass)

In this comprehensive deep‑dive, you’ll learn the nine essential RAG design patterns that cover every use case, from basic naive RAG to state‑of‑the‑art multi‑agent systems. The video explains when to use each pattern, how model selection shapes the architecture, and how to balance intelligence, speed, and cost. It also covers real‑world use cases such as customer‑facing chatbots, AI assistants for legal departments, background RAG systems in content workflows, and fully local RAG for resource‑constrained environments. Advanced multi‑agent orchestration strategies, query routing, transformation, fusion, and verification techniques are demonstrated with real n8n implementations, and bonus coverage of Self‑RAG, CorrectiveRAG, guardrails, human‑in‑the‑loop, context expansion, and deep RAG patterns is included.
