Why AI Hallucinates and How Retrieval-Augmented Generation Gives It a Research Assistant
Retrieval-Augmented Generation (RAG) equips large language models with a three‑step "retrieve‑augment‑generate" workflow, turning closed‑book AI into an open‑book system that lowers hallucinations, updates knowledge in real time, and improves answer accuracy, though it still faces retrieval errors and reasoning limits.
