DeepMind Paper Claims Current RAG Architectures Have Uncrossable Mathematical Limits

A recent paper from Google DeepMind argues that current RAG (Retrieval-Augmented Generation) architectures based on single-vector embeddings have an uncrossable mathematical limit.

For the past three years, the standard engineering solution to AI memory and data problems has been to chunk data and store it in a vector database. However, this research proves that compressing complex documents or queries into a single fixed-length vector has a core flaw. Simply throwing more parameters or compute at the problem will not make the search smarter.
