Is Agentic RAG Worth It? New Research

A January 2026 arxiv paper experimentally compares RAG approaches and finds agentic RAG outperforms static RAG for multi-hop reasoning tasks but adds latency and cost. Key pitfalls: "over-search" (redundant retrievals) and "under-search" (missing needed retrievals). Practical takeaway: only move to agentic RAG when your task genuinely requires iterative or conditional retrieval — not by default.
