``:ref:`ov::pass::ModelPass <doxid-classov_1_1pass_1_1_model_pass>``` is used for transformations that take entire ``:ref:`ov::Model <doxid-classov_1_1_model>``` as an input and process it.

Template for ModelPass transformation class

Using ``:ref:`ov::pass::ModelPass <doxid-classov_1_1pass_1_1_model_pass>```, you need to override the ``run_on_model`` method where you will write the transformation code.
|
|
Return value is ``true`` if the original model has changed during transformation (new operation was added, or operations replacement was made, or node attributes were changed); otherwise, it is ``false``.
|
|
Also ``:ref:`ov::pass::ModelPass <doxid-classov_1_1pass_1_1_model_pass>``` based transformations can be executed via ``:ref:`ov::pass::Manager <doxid-classov_1_1pass_1_1_manager>```.
