RAG Is Dead. Long Live the Agent That Replaced It.

Last year, every AI engineer I knew was building a RAG pipeline.
Retrieval-Augmented Generation was the shiny new hammer — the way to make large language models “smarter,” more grounded, and enterprise-ready.

You probably built one too.

But here’s the uncomfortable truth:
Your RAG pipeline is already obsolete.

AI has evolved — and what’s replacing RAG isn’t just a better retrieval system.
It’s something smarter.
Something autonomous.
Something that doesn’t just generate answers, but thinks, plans, and acts.

Welcome to the age of agentic AI.

When LLMs hallucinated or went off-script, RAG came to the rescue:

• Retrieve relevant documents from a knowledge base.
