Beyond Naive RAG: nine retrieval experts argue single-vector RAG is obsolete

A 2026 collection of talks titled Beyond Naive RAG, edited by Hamel Husain, has nine retrieval researchers argue that naive single-vector retrieval-augmented generation is obsolete.

Meng Shao, who posted a Chinese summary on X, reports that the talks recommend evaluating a system before optimizing it, keep retrieval in place even with long context windows, and treat simplicity as the default architecture. The summary is Shao's account of the book, and the report does not describe specific benchmark results.
