are building chains that are agnostic to the underlying language modeltype (e.g., pure text completion models vs chat models).
Parameters

stop (Optional[List[str]]) – Stop words to use when generating. Model output is cut off at the
first occurrence of any of these substrings.
callbacks (Optional[Union[List[BaseCallbackHandler], BaseCallbackManager]]) – Callbacks to pass through. Used for executing additional
functionality, such as logging or streaming, throughout generation.
**kwargs (Any) – Arbitrary additional keyword arguments. These are usually passed
to the model provider API call.
