Unverified按调用付费模式适合Agent这种任务驱动、工具动态选择的使用模式，使成本与实际价值产出精确对齐74% similarUnverifiedIn terms of Agent strategy selection, empirical testing shows that ReAct is more stable than Function Calling, especially with stronger fault tolerance in complex multi-step, multi-tool collaborative tasks.74% similarUnverifiedAn agent's behavioral chain is essentially a probabilistic reasoning process in which the same input may produce different tool-call sequences, which is what makes agent evaluation difficult.72% similarVerifiedIn LangChain's Agent architecture, the Agent itself is only responsible for reasoning and generating tool-call instructions, while the Agent Executor is responsible for executing tools, handling responses, and managing the iteration loop.72% similar
