Génération augmentée par récupération (RAG)
Retrieval-Augmented Generation (RAG) is a framework that allows Generative AI models to fetch fresh, external data from specific sources (like your website) before generating an answer. It bridges the gap between an LLM's frozen training data and real-time facts, reducing hallucinations and improving accuracy by treating structured data as a live knowledge base.
Why RAG is Critical for AI-Powered Search
Standard LLMs are stuck in the past—their training data has a cutoff date, meaning they can't know your current inventory, pricing, or product updates. RAG solves this by allowing an AI agent to actively fetch information from your website in real-time. Your JSON-LD schema acts as the "API" for this retrieval system. When a user asks an AI assistant about your products, RAG enables it to check your actual database and respond with accurate, up-to-date information instead of hallucinating outdated or incorrect details. This is essential for e-commerce, SaaS platforms, and any business where data changes frequently.
Static LLM vs. RAG-Powered System
Impact dans le monde réel
Customer asks ChatGPT about iPhone 15 pricing
AI: "I don't have current pricing information"
Customer leaves to check Apple.com manually
Same question with RAG system checking Apple's JSON-LD
AI: "The iPhone 15 is currently $799 on Apple.com"
Customer gets answer instantly, clicks citation link
