VerifiedFunction Calling is the core mechanism for large models to interact with external systems, allowing the model to call predefined functions after identifying user intent.80% 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76% 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).76% similar
