Overview

Let’s be honest for a second. When you are building a RAG (Retrieval‑Augmented Generation) pipeline, how do you pick your chunk_size and overlap?
If you are like 90 % of us, you copy‑paste 1000 and 200 from a tutorial, run it, and hope the LLM doesn’t hallucinate.
I realized I was doing “vibes‑based …”
