This article explains the underlying mechanism of function calling in large language models, clarifying that models do not directly execute functions but rather generate text that requests a function call. This process involves serializing tool schemas into the prompt, training the model to generate structured tool calls, and then parsing this output back into a usable format for the developer. Understanding this text-generation basis helps in debugging and optimizing tool usage within AI agents. AI
