php调用chatgpt的gpt-3.5-turbo-0613的functions笔记

最近，OpenAI更新了ChatGPT，将GPT-3.5 Turbo模型更新为GPT-3.5 Turbo-0613，支持最长16k的tokens，这是一个非常给力的更新。这意味着AI的能力正在不断增强。以前，AI只能写代码片段，理解短篇PDF文档等任务。但是，随着tokens数量的增加，未来AI将能够一次性读取长篇小说、大型项目的源码，并对其进行修改和总结等操作。

此外，OpenAI还增加了一个functions的调用功能。通过这个功能，用户可以将prompt和函数的参数及返回结果等信息发送给ChatGPT，让它帮你理解函数的参数并直接调用函数。这个功能非常实用，将改变应用的使用方式。以前，执行用户的指令需要理解用户的意图，容易出错。现在，通过ChatGPT生成函数的参数，执行指令变得更加容易。
