Solving the Relevancy Problem

Listen to full episode:

Summary: In this episode, Ed and Anant unpack how retrieval, context windows, and agentic systems are reshaping practical AI architecture. They argue that while the hype keeps shifting, the underlying need for strong data infrastructure has never gone away.

Sound Bites:

“RAG does not equal vector retrieval.”

“If you can’t depend on it, it’s entertainment.”

“The context window getting bigger, that’s awesome. That means maybe I don’t have to be as fine-grained in my chunking.”
