+### 3. 配置网络代理（可选）
+
+通过 `config.json` 的 `proxies` 数组为所有下游请求配置代理。数组为空表示直连；配置多个代理时会按照数组顺序轮询使用。
+
+```json
+{
+  "proxies": [
+    {
+      "name": "default-proxy",
+      "url": "http://127.0.0.1:3128"
+    },
+    {
+      "name": "auth-proxy",
+      "url": "http://username:password@123.123.123.123:12345"
+    }
+  ]
+}
+```
+
+- `url` 支持带用户名和密码的 `http://user:pass@host:port` 或 HTTPS 代理地址，必要时请为特殊字符进行 URL 编码。
+- 每次请求都会调用下一项代理，配置发生变化时索引会自动重置。
+- 当配置合法代理时，日志会输出类似 `[INFO] Using proxy auth-proxy for request to ...`，可用于验证命中情况。
+- 代理数组留空或所有条目无效时，系统自动回退为直连。
+
 #### 推理级别配置
 
 每个模型支持五种推理级别：
