Agentic RAG

RAG where an agent decides what to retrieve, when, and from which source — instead of a single static query.

Definition
Agentic RAG combines retrieval with agent loops. The model plans sub-queries, picks data sources (vector store, SQL, web), critiques results, and re-queries until it has enough evidence to answer. It handles ambiguous questions that classic single-shot RAG fails on.
Example
A finance assistant gets 'why did revenue drop in Q2?', runs a SQL query for raw numbers, retrieves the relevant board notes from a vector store, then pulls a competitor news article from the web before composing the answer.
