 - Enhances the ability to interact directly with large models, supporting text conversations, multimodal expressions, and more.
 - Improves interaction capabilities for common output types, such as providing options to copy or run code when outputting it.
+- Built-in OpenAI models are available, and you can also extend models in the following ways:
+  - Define variables for LLMs, agents, and other dialogue objects based on Langchain, which can be directly used in Prompt Cells.
+  - Extend your own models based on libro-ai.

 ### Sql Cell
 
 - Supports interaction capabilities for executing SQL commands.
 - Connect to SQL databases to write SQL code directly in the notebook.

 - 增强直接与大模型交互的能力，支持文本对话，多模态表达等。
 - 增强对于常见输出类型的交互能力，如在输出代码时给出复制、运行等操作能力。
+- 内置了 OpenAI 系列模型，您还可以通过以下方式扩展模型～
+  - 基于 langchain 定义 llm、agent 等可对话对象的变量，他们可以直接用在 Prompt cell 中。
+  - 基于 libro-ai 扩展自己的模型。
+- 支持选择聊天标识，使得选择该聊天标识的 Prompt Cell 都在一个聊天上下文中。
+- 支持 Prompt Cell 保存为一个变量，该变量即为 langchain 的 AIMessage。
