You want the in_bulk queryset method which, according to the docs:

Takes a list of field values (id_list) and the field_name for those values, and returns a dictionary mapping each value to an instance of the object with the given field value. If id_list isn’t provided, all objects in the queryset are returned. field_name must be a unique field, and it defaults to the primary key.

It takes a list of IDs, so you'll need to get that first via the values_list method:

ids = MyModel.objects.values_list('id', flat=True)
ids_to_model_instances = MyModel.objects.in_bulk(ids)
# {1: , 2: , 3: }
