A technical infographic comparing three types of Retrieval-Augmented Generation (RAG) architectures. It details the workflows for Classic RAG (vector-based), GraphRAG (entity-rich/relational), and Agentic RAG (reasoning-based with self-evaluation), highlighting the strengths of each from simple retrieval to adaptive multi-source reasoning. #RAG #GraphRAG #AgenticAI #LLM #AIArchitecture #GenerativeAI #VectorDB #KnowledgeGraph
