:param filter: An expression for filtering the results of the request. For field names both
snake_case and camelCase are supported.
- ``model`` supports = and !=. ``model`` represents the Model ID, i.e. the last segment of the
Model's [resource name][google.cloud.aiplatform.v1.Model.name].
- ``display_name`` supports = and !=
- ``labels`` supports general map functions that is:
-- ``labels.key=value`` - key:value equality
-- \`labels.key:\* or labels:key - key existence
-- A key including a space must be quoted. ``labels."a key"``.
:param page_size: The standard list page size.
:param page_token: The standard list page token. Typically obtained via
[ListModelsResponse.next_page_token][google.cloud.aiplatform.v1.ListModelsResponse.next_page_token]
of the previous
[ModelService.ListModels][google.cloud.aiplatform.v1.ModelService.ListModels]

:param order_by: A comma-separated list of fields to order by, sorted in ascending order. Use "desc"
after a field name for descending.
