UnverifiedFunction Call通过JSON Schema定义工具，能让大模型以接近100%的准确率生成合法的工具调用请求69% similarUnverifiedThe core mechanism of Function Calling is that developers describe external function signatures in JSON Schema format, and the model outputs structured JSON invocation instructions that conform to the schema specification.68% similarVerifiedFunction Call does not actually execute code; the model only outputs a structured JSON string, and the actual execution is performed by the host program.64% similarVerifiedFunction Calling机制中，开发者将工具的名称、功能描述、参数Schema（通常为JSON Schema格式）注入到模型的请求中，模型输出结构化的JSON而非自然语言来调用工具63% similar
