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. Adaptive Retrieval Router Architecture: Query → Router (extracts features, scores strategies) → Retriever (keyword/vector/hybrid) → Evaluator → Feedback Loop → TelemetryThe […]
