Beyond Vector Search: Building an Adaptive Retrieval Router for Agentic AI Systems
Author(s): Abi
Originally published on Towards AI.
A hands-on guide to making retrieval a learnable decision layer—with code, architecture, and production trade-offs.
Vector search works great for “one query, one answer” workflows. But agentic AI systems retrieve multiple times across a plan — and a small miss early becomes a compounding error that derails the entire task.
The article discusses the need for an adaptive retrieval system for agentic AI, highlighting the problems with static retrieval in dynamic workflows and illustrating the design of an adaptive retrieval router that improves decision-making through feedback loops, thereby addressing compounding errors and enhancing performance in retrieval tasks.
