Fresh agentic-RAG references worth bookmarking

Two new arXiv entries give a current map of where retrieval-augmented agents are heading.

The SoK: Agentic Retrieval-Augmented Generation systematization lays out a taxonomy, architectures, and an evaluation framework for agentic RAG — a good shared vocabulary if your team is past single-pass RAG and arguing about what to build next.

A-RAG proposes hierarchical retrieval interfaces to scale agentic RAG, treating retrieval as a layered tool the agent navigates rather than a flat lookup. Useful when your retrieval layer — not the model — has become the accuracy ceiling.
