UnverifiedFunction 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82% similarVerifiedFunction Calling is the core mechanism for large models to interact with external systems, allowing the model to call predefined functions after identifying user intent.82% 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.81% similarUnverifiedFunction Calling是模型层面的原子能力，而一个Skill可能包含多次Function Calling的编排、错误处理、重试策略和结果后处理78% 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).78% similar
