RAG & Grounding: Building AI on Your Own Data
Build AI that answers reliably from your documents — retrieval, reranking, evaluation, and production security.
A model's built-in knowledge is fixed, generic, and can't cite a source. Retrieval-Augmented Generation (RAG) grounds the model in your data — so it answers from evidence you control, with citations, and can be updated without retraining.
This hands-on course teaches RAG the way it's actually built in 2026: hybrid retrieval, reranking, contextual retrieval, honest evaluation, and the production concerns (permissions, freshness, cost) that make or break a real system. It pairs directly with the enterprise-prompting course's reliability theme.
What you'll be able to do
- Decide when RAG beats long context or fine-tuning
- Build a retrieval pipeline with hybrid search and reranking
- Evaluate a RAG system's retrieval and generation separately
- Ship RAG with per-user permissions, citations, and cost control
