RAG Architecture Needs Advanced Decision-Making Beyond Basic Retrieval

The article argues that basic retrieval-augmented generation (RAG) systems, which rely on simple top-k retrieval from document chunks, are insufficient for complex real-world applications. It highlights that answers can be spread across multiple document types and require multi-step retrieval processes. A more mature RAG architecture should treat retrieval as a series of decisions, including choosing the right source, method, and determining if evidence is sufficient, rather than a single similarity search.
