"""**Chat Models** are a variation on language models.

While Chat Models use language models under the hood, the interface they expose
is a bit different. Rather than expose a "text in, text out" API, they expose
an interface where "chat messages" are the inputs and outputs.

**Class hierarchy:**

.. code-block::

    BaseLanguageModel --> BaseChatModel --> <name>  # Examples: ChatOpenAI, ChatGooglePalm

**Main helpers:**

.. code-block::

    AIMessage, BaseMessage, HumanMessage
