前言

tool_choice
- “none” 就是不用tools， tools傳入也為味空
- auto，就是可能調用tool，或者不調用，agent loop，很多寫的范式都是，調用tool，就執行拿到結果進入下一個loop，如果不調用tool就直接
- required：必須使用其中一個到多個工具，這樣的agentloop可能就是tools里有對應的類似于stopTool，調用到就agent ending
- forced function： 只調用一個特定tool。
claude也是一樣的，就是傳入參數 required 為any了
parallel_tool_calls
parallel_tool_calls = True的時候返回的ChatCompletionMessage中的choice.message.tool_calls有多個 toolcall
為False的時候， 只能每次調用一個tool
Strict mode
“strict”= true的時候更能保證json output的輸出，這個參數感覺大家用的很少，實際上為true和false，對于tool的parameters寫法很多都可以等價
比如：
{"type": "function","function": {"name": "get_weather","description": "Retrieves current weather for the given location.","parameters": {"type": "object","properties": {"location": {"type": "string","description": "City and country e.g. Bogotá, Colombia"},"units": {"type": "string","enum": ["celsius", "fahrenheit"],"description": "Units the temperature will be returned in."}},"required": ["location"],}}
}
這個是我們平時很愛寫的寫法，看到的基本上都是這種，只會把一定需要的參數寫為required中，但openai的"strict"= true， 對type做一下修改是一樣的效果
{"type": "function","function": {"name": "get_weather","description": "Retrieves current weather for the given location.","strict": true,"parameters": {"type": "object","properties": {"location": {"type": "string","description": "City and country e.g. Bogotá, Colombia"},"units": {"type": ["string", "null"],"enum": ["celsius", "fahrenheit"],"description": "Units the temperature will be returned in."}},"required": ["location", "units"],"additionalProperties": false}}
}
加入 "null"的type
