NLP vs RAG
NLP (Natural Language Processing) and RAG (Retrieval-Augmented Generation) both come up in ai & ml conversations and get confused. Here's the plain-English difference, side by side, so you can use each one with confidence.
The key difference: NLP refers to natural language processing, while RAG refers to retrieval-augmented generation — they describe different things even when they show up in the same sentence.
NLP — Natural Language Processing
A branch of AI that helps computers understand, interpret, and manipulate human language.
RAG — Retrieval-Augmented Generation
An AI technique that combines information retrieval with text generation to produce more accurate and contextual responses.
When to use NLP
Reach for "NLP" when the conversation is specifically about natural language processing. A branch of AI that helps computers understand, interpret, and manipulate human language.
When to use RAG
Reach for "RAG" when the conversation is specifically about retrieval-augmented generation. An AI technique that combines information retrieval with text generation to produce more accurate and contextual responses.
FAQs

Are NLP and RAG the same thing?
No. They're often used in the same conversation because they're related, but they describe different concepts. NLP = Natural Language Processing. RAG = Retrieval-Augmented Generation.
