What Is Retrieval-Augmented Generation (RAG) | NiCE Cognigy
Retrieval-Augmented Generation (RAG)
Retrieval-Augmented Generation (RAG) is an AI architecture that enhances a generative language model by grounding its responses in content retrieved from a curated, up-to-date knowledge base — rather than relying solely on what the model learned during training. When a customer asks a question, a RAG system first retrieves relevant passages from company documents, FAQs, product manuals, or knowledge bases, then passes that context to the LLM, which generates a precise, grounded answer. RAG dramatically reduces hallucination, keeps responses accurate as policies and products change, and ensures AI Agents cite enterprise-approved knowledge. NiCE Cognigy's Knowledge AI module implements enterprise-grade RAG.
For enterprise teams, Retrieval-Augmented Generation (RAG) matters because real-world outcomes depend on how the capability is integrated, governed, and measured — not just on the underlying technology. RAG dramatically reduces hallucination, keeps responses accurate as policies and products change, and ensures AI Agents cite enterprise-approved knowledge.
Key Points
- Grounds LLM responses in content retrieved from verified enterprise knowledge sources
- Retrieves relevant passages first — LLM generates answers from those passages, not training data
- Dramatically reduces hallucination and keeps answers current as policies change
- Supports FAQs, PDFs, product manuals, web content, and custom knowledge sources
- Implemented as Knowledge AI in the NiCE Cognigy platform with full governance controls
