Use to represent the result of a chat model call with a single prompt.
This container is used internally by some implementations of chat model, it will
eventually be mapped to a more general LLMResult object, and then projected into
an AIMessage object.
LangChain users working with chat models will usually access information via
AIMessage (returned from runnable interfaces) or LLMResult (available via
callbacks). Please refer the AIMessage and LLMResult schema documentation for
more information.
