RAG in Production
Build RAG systems that survive real users.
Go from a toy retrieval demo to a production-grade RAG pipeline: ingestion, chunking, embeddings, indexing, retrieval, and generation, built and illustrated end to end. Then level up with advanced retrieval, rigorous evaluation, and agentic and graph RAG.
