Where are the models stored？

Hi everybody
I’m using 2.0.

When I see the results of the program, I wonder that where the classifier models that are called in the program are stored. As we can see with this' model_id = 2 'and so on(below), where are all the models stored？Are these models stored in a file for invocation, or are they stored on some other public platform?
