AbstractChatModel

[recursix]

Something like this:

class AbstractChatModel(ABC):
    @abstractmethod
    def __call__(self, messages: list[dict]) -> dict:
        pass

    def invoke(self, messages: list[dict]) -> dict:
        return self(messages)

    def get_stats(self):
        return {}

• make other ChatModle extend this.
• Don't implement get_stats if returning nothing
• do we still need both call and invoke?
  • If no, remove one of the two everywhere.
  • If yes, are they exactly the same? if so, just clone it in the base class.
