VerifiedThe tool-calling (Function Calling / Tool Use) capability enables LLMs to output structured intent instructions, which are captured by an external execution layer to actually operate on systems.78% similarVerifiedFunction Calling (Tool Use) is a standardized mechanism for large models to invoke external tools, where developers pre-declare tool names, descriptions, and parameter schemas, and the model autonomously determines when to make a call.77% similarUnverifiedThe Function Calling workflow consists of five steps: defining the function, the model reasoning whether to invoke it, generating the function call instruction and preparing parameters, the developer's code actually executing the function, and the model generating the final answer from the returned result.76% similarUnverifiedTools（Function Calling）是让大模型与自己内部系统进行通信的方式，基础大模型本身不具备调用外部API的能力76% similarUnverifiedPlanning capability relies on large language model Chain-of-Thought (CoT) reasoning, tool invocation is implemented via Function Calling or plugin mechanisms, and the orchestration layer plays the role of a workflow engine.71% similar
