--
-- * 'lmNameContains' - A string in the training job name. This filter returns only models in the training job whose name contains the specified string.
--
-- * 'lmCreationTimeAfter' - A filter that returns only models created after the specified time (timestamp).
--
-- * 'lmNextToken' - If the response to a previous @ListModels@ request was truncated, the response includes a @NextToken@ . To retrieve the next set of models, use the token in the next request.
--
-- * 'lmSortOrder' - The sort order for results. The default is @Ascending@ .

-- * 'lmCreationTimeBefore' - A filter that returns only models created before the specified time (timestamp).
--
-- * 'lmMaxResults' - The maximum number of models to return in the response.
