近期有个很火的话题啊，那就是CahtGPT，这玩意是美国OpenAI研发的聊天机器人，于2022年11月30日发布。

ChatGPT是人工智能技术驱动的自然语言处理工具，它能够通过学习和理解人类的语言来进行对话，还能根据聊天的上下文进行互动，真正像人类一样来聊天交流，甚至能完成撰写邮件、视频脚本、文案、翻译、代码等任务。

接下来带你一分钟学会开发自己的OpenAI的应用

如果您需要获取ApiFox或者postman类接口可以联系我哦。点击联系我

先体验下ChatGPT的魅力

生成API密钥

在我们开始使用 OpenAI API 之前，我们需要登录我们的 OpenAI 帐户并生成我们的API 密钥。
注册OpenAI账号需要科学上网，这里推荐一个中国区注册OpenAI账号试用ChatGPT指南，可自行百度，链接贴不上来😂

账号注册完毕后，点击右上角，如下图

可以看到如下，就可以创建APIKEY了，记住它，接下来会用到

OpenAI的Restful接口

API接口是不需要翻墙的

列举可用模型

请求

GET https://api.openai.com/v1/models
Accept: application/json
Authorization: Bearer 上面注册的APIKEY
User-Agent: Apifox/1.0.0 (https://www.apifox.cn)
Accept: */*
Host: api.openai.com
Connection: keep-alive

响应

这个响应有点长啊，就不贴了

检索模型

请求

GET  https://api.openai.com/v1/models/text-davinci-003 HTTP/1.1
Host: api.openai.com
Authorization: Bearer 上面注册的APIKEY
User-Agent: Apifox/1.0.0 (https://www.apifox.cn)

响应

创建补全

请求

POST https://api.openai.com/v1/completions HTTP/1.1
Host: api.openai.com
Authorization: Bearer 上面注册的APIKEY
User-Agent: Apifox/1.0.0 (https://www.apifox.cn)
Content-Type: application/json
Accept: */*
Host: api.openai.com
Connection: keep-alive

{
    "model": "text-davinci-003",
    "prompt": "用python画一朵玫瑰花",
    "max_tokens": 100,
    "temperature": 0
}

参数说明

• model ：要使用的模型的 ID（在这里你可以看到所有可用的模型）
• Prompt：生成结果的触发指令
• max_token：完成时生成的最大token数量（这里可以看到OpenAI使用的tokenizer）
• temperature：要使用的采样策略。 接近 1 的值会给模型带来更多风险/创造力，而接近 0 的值会生成明确定义的答案。
