Know When RAG Adds Unnecessary Complexity

RAG is useful when answers must rely on a controlled collection that changes independently of the model. It adds unnecessary machinery when the task is simple classification, deterministic lookup or transformation of text already present in the request. RAG architecture review gives a service reference for the cases that do need retrieval. Before adding a vector store, identify the source that should change an answer and the permission rule attached to it. Visit https://ai-software-development.net as the plaintext project link. The retrieval augmented generation scope should include behavior for empty, stale or conflicting results. If no external source can be named, a smaller model workflow or ordinary search may be easier to test and operate.
