What is the equivalent of django.db.models.loading.get_model() in Django 1.9?

I want to use get_model() to avoid cyclic imports in my models, but I get name 'get_model' is not defined error. I read that get_model() was depreciated in 1.8 and apparently is not present in 1.9. What is the equivalent call? Or is there another way to avoid cyclic imports in two models.py files?
