About Course
Retrieval-augmented generation (RAG) lets an AI assistant answer questions using your organisation’s own documents rather than only what the model learned in training. Learn how RAG works step by step, including chunking, embeddings and vector search, what it does well, where it goes wrong, and the security questions to ask, such as permissions and prompt injection.
