Tool Calling is a capability of large language models: when generating a reply, the model outputs structured JSON indicating which function to call and what parameters to pass, but the model only outputs intent and does not execute code; the responsibility for execution lies on the application side.

VerifiedAgents use the Tool Calling mechanism to allow models to output calling intent in a structured JSON format, with external programs executing the actual operations and feeding results back to the model.80% similarUnverified当模型决定调用工具时会生成带tool_calls字段的AIMessage,工具执行结果以ToolMessage形式回传给模型形成工具调用闭环79% similarVerifiedTools (Function Calling) is the method by which large models communicate with one's own system, achieved by registering business method names, descriptions, and parameter structures with the large model to enable invocation.78% similarVerified工具调用(Function Calling/Tool Use)是Agent系统的核心能力,允许模型动态调用搜索引擎、代码解释器、数据库查询、API接口等外部资源74% similar
