One of the main challenges of generative AI in business is the reliability of its responses. How can we ensure that an AI agent isn't "hallucinating," that it's relying on verified and up-to-date data? The answer lies in three letters: RAG (Retrieval-Augmented Generation).
RAG: what is it and why is it essential?
RAG is an architecture that combines the power of Language Learning Models (LLMs) with information retrieval from a document database. Specifically, before generating a response, the AI agent will first search for relevant information in your internal documents, then use it to construct a precise, sourced and coherent answer.
This is the fundamental difference between a "naked" LLM — which only knows its training data — and a AI agent augmented by your company data.
What internal documents can be used to populate the RAG?
On a platform like AI-Enterprise, you can connect a wide variety of sources:
- Internal policies and procedures quality manuals, charters, regulations
- Product documentation Technical specifications, user manuals, FAQs
- Regulatory data standards, compliance, applicable laws
- Knowledge bases Training guides, best practices, feedback from experience
- Contracts and legal documents General terms and conditions, framework agreements
These documents are indexed and made available to all AI agents configured on the platform. When a document is updated, the agents automatically receive the new version.
The concrete advantages of RAG in business
1. Reliable and sourced answers
Each answer is based on excerpts from your internal documents. The agent doesn't "guess": they quote and rephrase from verified sources. This significantly reduces the risk of hallucination.
2. Complete documentary consistency
All agents in your organization share the same document database. Whether it's the sales department, compliance, or customer support, everyone receives answers aligned with the same reference data.
3. Real-time updates
When an internal policy changes, a product evolves, or regulations are updated, simply replace the source document. All AI agents benefit immediately, without manual reconfiguration.
4. Compliance with confidentiality requirements
The documents remain within your secure perimeter. With AI-Enterprise, you choose cloud or on-premise hosting, and access rights determine which agents (and which users) can access which sources.
RAG and enterprise metadata: a powerful combination
The RAG does not work alone. On AI-Enterprise, it is combined with the centralized enterprise metadata Product catalogs, sales offers, technical data, key messages. Result: an AI agent that knows both your procedures (via the RAG) and your products (via metadata), for complete and actionable answers.
Concrete use cases
- Sales support An AI agent answers prospects' questions based on your product sheets and commercial terms.
- Compliance An agent verifies that an internal process complies with current regulations.
- Onboarding An agent guides new employees through internal procedures and available resources.
- Legal An agent analyzes a contract by comparing it to your standard templates and conditions.

Conclusion: RAG, a pillar of reliable AI in business
RAG is not an option—it's a prerequisite for any organization that wants to deploy generative AI reliably and responsibly. By connecting your internal documents to your AI agents, you get accurate, up-to-date answers that are aligned with your repositories.
