前言

一个月前马斯克开源了自家的大语言模型 grok-1 并顺带着嘲讽了一下 OpenAI,想看看 OpenAI 关于 “Open” 的部分。

这波我肯定是站马斯克了,记得第一次听说 OpenAI 名字的时候,还以为这是一个研究 AI 的开源社区,应为它遵循了 OpenCV, OpenGL 这样的命名模式。

后来 GPT-4 需要一个月 20 刀的时候,也算是认清 OpenAI 的真面目了。

自从大语言模型诞生以来,中国民众想使用 AI 服务是真的难。可谓是双向卡脖子,一方面阿美丽卡的公司不对中国开放服务。另一方面国民无法访问自由的互联网。

最近,ChatGPT-3.5 可以免注册使用了(它总算是 Open 了一小部分😂),也就是说对于我们来说又少了一道使用 ChatCPT 的门槛。

这篇博客介绍了一种访问 chat.openai.com 的方法。

基于 Cloudflare 搭建 Vless 节点

既然 chat.openai.com 已经可以免注册使用了,那么原则上我们就只剩下 GFW 这一个障碍了。但并不是任何一个梯子都可以访问 chat.openai.com 的,比如我的甲骨文云的梯子就不行。

原因在于 OpenAI 屏蔽了许多知名云服务提供商的 IP,也就是专门针对我们这些使用代理的用户设置的障碍。

把代理节点搭建在 Cloudflare 家里,使用 Cloudflare 的 IP 就可以正常访问 chat.openai.com 了。

免费的东西,建议人手一个。

节点搭建

  1. 登录 Cloudflare

    https://www.cloudflare.com/

  2. 按下图操作依次执行

  1. 进入到编辑代码界面后,删除默认内容,然后复制下面的代码并粘贴到 worker.js 代码框中

获取节点配置

完成部署后,使用你的 UUIDWorker 域名 替换如下字符串来获得分享链接

vless://UUID@www.visa.com.sg:8880?encryption=none&security=none&type=ws&host=Workers domain&path=%2F%3Fed%3D2048#Workers domain

例子:

vless://60da4750-617a-42a3-97a2-8ccdc2b45589@www.visa.com.sg:8880?encryption=none&security=none&type=ws&host=freedom.wgx.workers.dev&path=%2F%3Fed%3D2048#freedom.wgx.workers.dev

获得配置链接后,导入你的代理客户端,就可以开启科学上网之旅了。
