RAG works by converting documents into embeddings, storing them in a vector database, and then retrieving relevant passages to augment the prompt when a question is asked, enabling more factual and verifiable answers.

    What Is RAG? Retrieval-Augmented Generation Explained (2026)

    <p>Ask a language model about your company's refund policy and it will answer with complete confidence. The catch is that it has never seen your refund policy. It is guessing from patterns, and sometimes the guess sounds so reasonable that nobody notices until a customer does.</p…
