Agentic RAG

RAG in which an agent decides when, where and how to retrieve, possibly over multiple iterations and sources.

Definition

Instead of a single retrieve-then-generate step, the model plans queries, calls search tools, evaluates results and retrieves again as needed. It handles complex questions at the cost of more latency and tokens.

Exam tip

Agentic RAG improves complex answers but adds latency, cost and more failure points than single-step RAG.
