Retrieval-Augmented Generation (RAG) fetches live data from external sources for accurate, up-to-date responses but is slower and more expensive. Cache-Augmented Generation (CAG) uses pre-stored information for faster, cost-effective answers but risks serving outdated content. RAG suits scenarios requiring real-time accuracy like financial updates or unpredictable queries, while CAG excels at repetitive tasks like FAQ chatbots. Hybrid approaches combine both, using cached responses for speed while falling back to live retrieval when needed. The choice depends on query patterns, budget, performance requirements, and data freshness needs.
