VerifiedFunction Calling 的底层实现并非模型真正执行函数，而是模型输出结构化调用意图描述，由宿主程序实际调度执行并将结果回传给模型80% similarUnverifiedThe LLM in Function Calling does not execute code directly, but generates structured descriptions of calling intent, decoupling decision-making from execution79% similarUnverifiedFunction Calling本质上是模型决策、外部执行的两阶段流程，模型本身并不直接运行代码79% similarUnverified函数调用中模型本身无法主动执行代码，仅识别意图并生成符合函数签名的结构化参数，实际执行由调用方负责79% similarUnverifiedFunction Calling采用关注点分离设计，语言模型只负责决策，真正的工具执行由应用层代码负责，模型不直接触碰外部系统77% similar
