#### *property* Session.chat *: [Chat](./atoti_ai.chat#atoti_ai.Chat) | [None](https://docs.python.org/3/library/constants.html#None)*

The Atoti Chat configuration.

`None` if [`atoti_ai.AiConfig.connection`](./atoti_ai.ai_config#atoti_ai.AiConfig.connection) or [`atoti_ai.AiConfig.chat`](./atoti_ai.ai_config#atoti_ai.AiConfig.chat) are `None`.

`None` when Atoti Intelligence is disabled or no LLM is configured:

>>> session.chat is not None
True
```
