Why RAG Produces More Trustworthy Answers

 

✍️ 

🚀 Introduction

One of the biggest challenges with AI is accuracy.

This problem is addressed by:

👉 RAG (Retrieval-Augmented Generation)


🎯 Objective: GROUND

Instead of relying only on the model's memory, RAG retrieves information from external sources first.

📚 Example

Question:

Plain Text
1

GenAI may guess.

RAG will:

Generate answer

✅ Benefits

More Accurate
