+# Bingo OpenAI 
+
+为了方便将 `new bing` 接入到其他 `gpt` 类的项目，现开放 `OpenAI` 格式的 `API` 接口供大家调用。
+
+## 接口说明
+### 入参
+ * url: /openai/chat/completions (PS: 为了方便兼容不同的项目，所有以 `/completions` 结尾的请求都会被支持)
+ * Content-Type: application/json
+ * 参数说明
+    * messages 输入的消息列表，完整格式参见 https://platform.openai.com/docs/guides/gpt/chat-completions-api
+    * model 模型名称（此字段被用于指定 new bing 风格，参数为 Creative、Balanced、Precise 中的一种）
+    * stream 是否使用流式输出，默认为 
+    
+### 出参
+  * Content-Type: application/json 或者 text/event-stream
+  * 参数说明
+    * choices 返回的消息内容，完整格式参见 https://platform.openai.com/docs/guides/gpt/chat-completions-response-format
+    * id 会话 ID，如需保持上下文，则需要传入此参数，否则会丢失上下文
+
+### 示例
+以下以 `curl` 为例
+```
+curl -kL 'https://hf4all-bingo-api.hf.space/api/v1/chat/completions' \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "messages":[{"role":"user","content":"你好"}],
+    "stream":true,
+    "model":"Creative"
+  }' \
+--compressed
+```
+
+### 限制
+ * 暂时只支持聊天(`/completions`)接口，其他接口如有需求，请在 [issue](https://github.com/weaigc/bingo/issues) 提出
+ * 受 new bing 限制，暂不支持自定义历史记录
+
+## 调用方式
+除了使用 HTTP POST 请求来调用之外，你也可以使用自己熟悉的方式来调用 new bing，如 python 的 openai 库或其它语言的同名包。下面例举一下 Python 和 Node.js 的用法
+
+### Python
+```
+import openai
+openai.api_key = "dummy"
+openai.api_base = "https://hf4all-bingo-api.hf.space" # 这里可以改为你自己部署的服务，bingo 服务版本需要 >= 0.9.0
+
+# create a chat completion
+chat_completion = openai.ChatCompletion.create(model="Creative", messages=[{"role": "user", "content": "Hello"}])
+
+# print the completion
+print(chat_completion.choices[0].message.content)
+```
+
+流式输出
+```
+
+```
+> 更多使用说明参考 https://github.com/openai/openai-python
+
+### Node.js
+```
+import OpenAI from 'openai';
+
+const openai = new OpenAI({
+  baseURL: 'https://hf4all-bingo-api.hf.space' // 这里可以改为你自己部署的服务，bingo 服务版本需要 >= 0.9.0
+});
+
+async function main() {
+  const stream = await openai.chat.completions.create({
+    model: 'Creative',
+    messages: [{ role: 'user', content: 'Hello' }],
+    stream: true,
+  });
+  for await (const part of stream) {
+    process.stdout.write(part.choices[0]?.delta?.content || '');
+  }
+}
+
+main();
+```
+> 更多使用说明参考 https://github.com/openai/openai-node
