We Built an Alternative to Vector RAG for AI Agent Memory
This article introduces Agentic RAG as a new approach to AI agent memory, where retrieval is an active tool controlled by the agent, rather than a fixed pipeline. It suggests this method is more suitable for complex AI agent workflows than traditional vector RAG.
Why it matters
This development could significantly impact how AI agents access and utilize external information, potentially leading to more sophisticated and adaptable AI systems. It challenges the current standard in Retrieval-Augmented Generation.
Back to blog RAG · Agents October 5, 2026 By Gael Anaya RAG for AI Agents: Why Agentic Retrieval Is Replacing Fixed Vector Pipelines Agentic RAG treats retrieval as a tool the agent can invoke, evaluate and repeat. Vector databases remain useful, but they should not be the first architecture for every document agent.
RAG for AI agents gives an agent access to external information while it reasons and acts. Agentic RAG treats retrieval as a tool the agent can invoke, evaluate and repeat. Vector databases, embeddings and chunking remain useful, but they should not be the first architecture for every document-agent workflow.
Retrieval-Augmented Generation has become one of the standard ways to connect language models to external information. The traditional approach is familiar: split documents into chunks, generate embeddings, store those vectors in a database and retrieve the nearest passages before asking the model to answer.
