RAG: Giving AI a Brain Upgrade

Retrieval-Augmented Generation (RAG) is a technique that enhances Large Language Models (LLMs) like GPT-4 by connecting them to external, private data sources.

The problem it solves

LLMs hallucinate and don't know about your specific business data. RAG retrieves relevant facts from your documentation/database first, then feeds them to the AI to generate an accurate answer.

Use cases

  • Customer Support Chatbots: "What is your return policy for Item X?" (RAG looks up the policy, AI writes the polite answer).
  • Internal Search: Employees asking "How do I file expenses?" and getting a summarized answer from the company handbook.
