When a single LLM is tasked with answering thousands of queries per second, latency, cost, and knowledge consistency quickly become bottlenecks. A multi‑agent RAG system—where many specialized agents collaborate, each handling retrieval, reasoning, or generation—offers a path to both scalability and functional decomposition. ...
