LangChain Architecture

Acerca de

LangChain Architecture provides comprehensive guidance for developers building production-grade AI applications. It covers essential patterns for creating autonomous agents with tool access, managing conversation history across diverse memory types, and implementing efficient Retrieval-Augmented Generation (RAG) pipelines. By offering modular templates for chains and document processing, this skill helps developers move from basic prompts to complex, multi-step workflows while ensuring observability through integrated callback systems and robust testing strategies.
