A state machine decomposes complex processes into discrete state nodes and defines transition conditions between nodes; LangGraph explicitly manages transition relationships through a graph structure and maintains a state object that persists throughout execution, with the core difference from chained calls being that it allows loops, branches, and interrupt recovery.

UnverifiedIn LangGraph, each node represents a computation step (such as an LLM call, tool execution, or conditional judgment), and edges represent state transition paths.75% similarUnverifiedCompared with the early chain-style calls of LangChain, LangGraph supports cyclic execution, conditional branching, and persistent state74% similarUnverifiedGraph structures are more suitable than chain structures for expressing an Agent's decision loop, and can represent complex control flows such as conditional branching, loops, parallel execution, and state backtracking.71% similarUnverifiedIn LangGraph, Nodes represent processing units, Edges define flow logic, State is the continuously passed shared context, and Reducer functions control the concurrent update strategy.71% similarUnverifiedIn a graph structure, agents or processing nodes are abstracted as graph nodes (Nodes), and the invocation relationships, conditional branches, and loops between nodes are abstracted as edges (Edges), which naturally support parallel execution, conditional jumping, and loop backtracking compared to linear Chains.71% similar
