UnverifiedFunction 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85% similarVerifiedThe underlying implementation of Function Calling does not involve the model actually executing a function; instead, the model outputs a structured description of the calling intent, and the host program actually dispatches the execution and returns the result to the model.84% similarUnverifiedFunction Calling refers to the model declaring, when generating a response, that a specific function needs to be called with specific parameters, which is then executed by an external system and the result returned to the model.82% similarVerifiedWhen a large model executes Function Calling, it does not actually perform the call itself—it only outputs an intent declaration, and the actual execution is completed by the host application.79% similarVerifiedThe principle of Function Calling is that, in addition to generating natural language text during inference, the model can also output structured function-call instructions (JSON containing the function name and parameters).79% similar
