LangChain
Walks through LangChain's component model and chain orchestration, then shows how prompt templates, retrieval augmentation, memory and tracing support RAG pipelines, assistants and automation in production.
LangChain is an open-source framework for building large language model applications. Reusable components turn model calls, tool connections and business steps into maintainable chains, covering prompt templates, retrieval augmentation, memory and agents, while tracing keeps failures on long call paths easy to locate. Being code-first, RAG pipelines and assistants share one versionable orchestration layer.
