之前写了一个tg机器人，但是一直没有继续去写，所以他只会echo。最近觉得手机上使用GPT有些麻烦，于是决定让机器人接入GPT。经过了解发现OpenAI的官方API缺点如下：

• 只能用信用卡付款。
• 并发很低，一分钟只能调用几次。
• 假如服务器在国内就无法连接。

于是去寻找第三方API替代，最终找到了AI Proxy。(官网地址：AIProxy)看了下定价应该是比官方稍贵一点：

gpt4尚未测试过实际消耗，如果是gpt-3.5-turbo，实际消耗比标的Max Per Request还要低得多。

注册登录后充值积分（充值时输入邀请码：IAMCZY，可以赠送额外3%积分）。随后在控制台中找到API Key，修改一下我们之前的机器人代码就好啦
