Does Agentic RAG always produce better answers than traditional RAG?
No — it produces better answers on questions where a single retrieval pass is insufficient, at the cost of more latency and more LLM calls per query. For simple factual lookups where one good retrieval reliably contains the answer, traditional RAG is faster and cheaper with no quality loss. Agentic RAG earns its cost on genuinely multi-step or ambiguous queries, not universally.
