 # ChatGPT API WEB

-> 灵车东西，做着玩儿的
+ChatGPT API WEB 是为 ChatGPT 的日常用户和 Prompt 工程师设计的项目。它让你方便地在 PC 和移动端浏览器上使用 ChatGPT，并根据需要调整系统 Prompt 和修改 OpenAI 接口参数。你还可以重复生成、编辑消息（包括用户消息与 AI 消息），以更好地与 ChatGPT 进行交互。

-一个简单的网页，调用 OPENAI ChatGPT 进行对话。
+无论你是 ChatGPT 的一般用户、想要定制 ChatGPT 的用户，还是 Prompt 工程师，这个项目都能满足你的需求。

 - API 调用速度更快更稳定
 - 对话记录、API 密钥等使用浏览器的 localStorage 保存在本地
- 可删除对话消息
- 可以设置 system message (如："你是一个猫娘" 或 "你是一个有用的助理" 或 "将我的话翻译成英语"，参见官方 [API 文档](https://platform.openai.com/docs/guides/chat))
+- 可编辑并删除对话消息
+- 可以导入/导出整个历史对话记录
+- 可以设置 system message (参见官方 [API 文档](https://platform.openai.com/docs/guides/chat)) 例如：
+  - > You are a helpful assistant
+  - > 你是一个专业英语翻译，把我说的话翻译成英语，为了保持通顺连贯可以适当修改内容。
+  - > 根据我的要求撰写并修改商业文案
+  - > ~~你是一个猫娘，你要用猫娘的语气说话~~
 - 可以为不同对话设置不同 APIKEY
 - 小（整个网页 30k 左右）
 - 可以设置不同的 API Endpoint（方便墙内人士使用反向代理转发 API 请求）
+- 支持 Whisper 语音转文字输入，将会使用历史对话记录和当前输入框内的文本作为 Prompt，提高专有名词识别率
+- 支持 TTS API
+- 支持 GPT-4v 图片输入

 - 自行编译构建网页

+### 默认参数继承
+
+新建会话将会使用 URL 中设置的默认参数。
+
+如果 URL 没有设置该参数，则使用 **目前选中的会话** 的参数
+
 ### 更改默认参数

 - `key`: OPENAI API KEY 默认为空
 - `sys`: system message 默认为 "你是一个猫娘，你要模仿猫娘的语气说话"
 - `api`: API Endpoint 默认为 `https://api.openai.com/v1/chat/completions`
 - `mode`: `fetch` 或 `stream` 模式，stream 模式下可以动态看到 api 返回的数据，但无法得知 token 数量，只能进行估算，在 token 数量过多时可能会裁切过多或过少历史消息
+- `dev`: true / false 开发模式，这个模式下可以看到并调整更多参数
+- `temp`: 温度，默认 1
+- `whisper-api`: Whisper 语音转文字服务 API, 只有设置了此值后才会显示语音转文字按钮
+- `whisper-key`: 用于 Whisper 服务的 key，如果留空则默认使用上方的 OPENAI API KEY

 例如 `http://localhost:1234/?key=xxxx&api=xxxx` 那么 **新创建** 的会话将会使用该默认 API 和 API Endpoint
