Top 10 Generative AI Architecture Patterns for Large Enterprises

1. RAG (Retrieval-Augmented Generation) Pattern

A foundational pattern that enhances Large Language Models by retrieving relevant information from external knowledge bases before generating responses. This pattern combines the generative capabilities of LLMs with the accuracy and freshness of retrieved documents, reducing hallucinations and providing source attribution.

When to Use

Use this pattern when you need to provide accurate, up-to-date information that may not be in the LLM's training data, when you require source attribution for generated content, or when working with proprietary or domain-specific knowledge bases. Ideal for customer support systems, knowledge management platforms, and technical documentation assistance.
