Building RAG Applications
A hands-on, intermediate course on Retrieval-Augmented Generation (RAG). Move beyond basic prompting and learn to build production-grade RAG pipelines using LangChain and LlamaIndex — covering text chunking, embedding models, vector stores, hybrid retrieval, advanced patterns like HyDE and query decomposition, and evaluation with RAGAS. Every module includes real Python code you can run today.
