UnverifiedOpenAI's function calling/tool use mechanism is a hard constraint; the model inference engine directly constrains the valid set of output tokens during the decoding phase, thereby guaranteeing format compliance at the protocol level.83% similarUnverifiedIn OpenAI's Function Calling, developers declare function names, parameter types, and descriptions in advance, and the LLM autonomously determines when and which function to call during inference, returning a structured call request to the application layer for execution.82% similarUnverifiedOpenAI自GPT-4起引入了结构化的Function Calling机制，允许模型在对话中动态决定何时调用哪个工具、传入什么参数，并将结果整合回答复中82% similarUnverified函数调用（Function Calling）让模型能够调用外部函数和API与真实业务系统对接80% similarVerifiedOpenAI launched the Function Calling specification in 2023, allowing developers to describe function interfaces in JSON Schema format, with the model autonomously deciding when to call them and what parameters to pass.79% similar
