Is LangChain just one library? The docs reveal a deliberate three-layer architecture designed for different levels of control. We explore the low-level orchestration of LangGraph, the high-level components of LangChain, and the "batteries-included" Deep Agents framework. Learn why the new Functional API lets you write agents as standard Python functions, how virtual filesystems solve context limits, and why durable execution changes debugging forever.
