 > 大多数 OpenAI 客户端不支持 Azure OpenAI Service，但Azure OpenAI Service的申请和绑卡都非常简单，并且还提供了免费的额度。此脚本使用免费的 Cloudflare Worker 作为代理，使得支持 OpenAI 的客户端可以直接使用 Azure OpenAI Service。
 
+### 项目说明:
+- 我没有服务器可以使用吗?
+    - 这段脚本跑在Cloudflare Worker, 不需要服务器, 不需要绑卡, 每天10W次请求 免费
+- 我没有自己的域名可以使用吗?
+    - 也可以, 参考: https://github.com/haibbo/cf-openai-azure-proxy/issues/3
+- 实现打印机模式：
+    - Azure OpenAI Service's 回复是一段一段回复的（当前仅GPT-4有此问题， GPT-3的问题Azure已经解决）
+    - 返回给客户端的时候， 本项目拆出一条条的消息, 依次给， 达到打印机模式
+- 项目也支持 Docker 部署（基于 wrangler）

 代理 OpenAI 的请求到 Azure OpenAI Serivce，代码部署步骤：
 
 1. 注册并登录到 Cloudflare 账户
 2. 创建一个新的 Cloudflare Worker
 3. 将 [cf-openai-azure-proxy.js](./cf-openai-azure-proxy.js) 复制并粘贴到 Cloudflare Worker 编辑器中
