LangChain vs LlamaIndex vs LangGraph en 2026: Matriz de decisión arquitectónica

LangGraph provides cyclical state machine execution and checkpoint persistence for autonomous multi-agent loops. LlamaIndex remains the gold standard for dense heterogeneous document ingestion, recursive chunking, and semantic vector retrieval.

Design resilient loops with typed dictionaries, conditional router edges, and circuit-breaker iteration caps.

Modern enterprise architectures standardize on LlamaIndex for knowledge retrieval coupled with LangGraph for execution orchestration.
