7 Levels of RAG Apps

#rag #ai #machinelearning #python

7 levels of RAG apps — which level is yours at?

1 Notebook · 2 Chunker · 3 Hybrid (dense + BM25) · 4 Re-ranker · 5 Gatekeeper (a confidence gate that refuses to answer) · 6 Auditor (citations + 196 tests) · 7 Operator (multi-provider fallback, ~220 MB in prod).

Level 7 is RAG.NextUpgrad, which I built and open-sourced: github.com/Pranjulrathour/RAG.NEXTUPGRAD · write-up at pranjulrathour.scult.in/projects/rag-nextupgrad

I teach this as a hands-on college workshop, free for student communities. Pranjul Rathour · GenAI engineer, Kanpur · pranjulrathour41@gmail.com
