LLM vs RAG vs Agent in one line: knows, looks up, does
techNmak · x · 2026-09-08
A minimalist explainer tweet distinguishing three terms in one line each:
- LLM = knows things
- RAG = knows things + looks things up
- Agent = knows things + looks things up + does things
Low information density, but a crisp way to explain the progression to non-technical readers.
