 # ChatGPT Web
 
-使用 express 和 vue3 搭建的 ChartGPT 演示网页
+使用 `express` 和 `vue3` 搭建的支持 `ChatGPT` 双模型演示网页
 
 ![cover](./docs/cover.png)
 ![cover2](./docs/cover2.png)
 
-> 提示：目前 `OpenAI` 开放的模型最高只有 `GPT-3`，和现在网页所使用的 `GPT-3.5` 或 `GPT-4` 有很大差距，需要等官方开放最新的模型接口。
+## 介绍
+
+支持双模型，提供了两种非官方 `ChatGPT API` 方法
+
+|  方式   | 免费？  | 可靠性  | 质量 |
+|  ----  | ----  | ----  | ----  |
+| `ChatGPTAPI(GPT-3)`  | 否 | 	可靠 | 较笨 |
+| `ChatGPTUnofficialProxyAPI(网页 accessToken)`  | 	是 |  不可靠 | 聪明 |
+
+***Note:*** 网页 `accessToken` 存在大约 8 小时，而且国内地区网络问题更推荐使用 `GPT-3` 的方式
+
+对比：
+1. `ChatGPTAPI` 使用 `text-davinci-003` 通过官方`OpenAI`补全`API`模拟`ChatGPT`（最稳健的方法，但它不是免费的，并且没有使用针对聊天进行微调的模型）
+2. `ChatGPTUnofficialProxyAPI` 使用非官方代理服务器访问 `ChatGPT` 的后端`API`，绕过`Cloudflare`（使用真实的的`ChatGPT`，非常轻量级，但依赖于第三方服务器，并且有速率限制）
+
+切换方式：
+1. 进入 `service/.env` 文件
+2. 使用 `OpenAI API Key` 请填写 `OPENAI_API_KEY` 字段 [(获取 apiKey)](https://platform.openai.com/overview)
+3. 使用 `Web API` 请填写 `OPENAI_ACCESS_TOKEN` 字段 [(获取 accessToken)](https://chat.openai.com/api/auth/session)
+4. 同时存在时以 `OpenAI API Key` 优先
+
+反向代理：
+
+`ChatGPTUnofficialProxyAPI`时可用 [详情](https://github.com/transitive-bullshit/chatgpt-api#reverse-proxy)
+
+```shell
+# service/.env
+API_REVERSE_PROXY=
