 In addition, you need to apply for the DuerOS profile on the [DuerOS Open Platform](https://dueros.baidu.com/didp/doc/overall/console-guide_markdown) in advance, and replace the empty file in `ADF_PATH/components/dueros_service/duer_profile`.
 
+## `WenXinYiYan` support
+
+This example can access to `WenXinYiYan` which provided by baidu. Interacting with the cloud through this example, responses from the AI can be obtained, providing richer and more intelligent answers.
+
+To integrate "WenXinYiYan", a profile with feature enabled is needed. So, please enable this requirement when applying for the DuerOS profile.
+
+With the correct profile and after compiling and flashing the profile and program as described below, we can interact with the AI after wake up the device.

 此外，本例程需要预先在 [百度 DuerOS 开放平台](https://dueros.baidu.com/didp/doc/overall/console-guide_markdown) 申请 DuerOS 的 profile，并替换 `ADF_PATH/components/dueros_service/duer_profile` 中的空文件。
 
+## 文心一言
+
+本例程已经支持接入百度`文心一言`，使用本例程与云端交互，可以得到来自大模型更加丰富与智能的结果。
+
+接入`文心一言`需要使用开通此功能的 profile，在申请 DuerOS profile 时请明注意勾选该需求。
+
+在有正确的 profile 并按照下文介绍的步骤编译并烧录 profile 与程序之后，唤醒设备就可以与`文心一言`进行交互。
