Agentic RAG

Agentic RAG puts the agent in charge of retrieval instead of running one similarity search and hoping. The agent decides when to search, what to search for, and whether results are good enough, reformulating bad queries, searching multiple sources, and flagging contradictions in retrieved context. The book's analogy: basic RAG is ten blue links; agentic RAG is a research analyst who reads, evaluates, and synthesizes.
