About this lesson

Most RAG evaluations fail before they start — generate a synthetic RAG test set from your docs to make retrieval regressions measurable. Get reproducible questions and reference answers so you can quantify context_precision, detect retrieval/answer drops, and make retriever changes actionable. Hands-on demo uses Ragas, OpenAI LLMs, embeddings, Hugging Face Dataset and a simple Python retriever — scalable to ANN indexes.
