Master the art of RAGs (Retrieval-Augmented Generations) without relying on frameworks like LangChain or LlamaIndex! In this video, we’ll guide you step-by-step to build 4 powerful RAGs—two in Python and two in JavaScript—all from scratch. Learn how to use embeddings, fetch data from the web, and work with APIs to create highly efficient RAG systems.

✨ No frameworks, no shortcuts—just raw Python and JavaScript magic.
