How many (classes of) objects can YOLO detect?

[ridvanozdemir]

I have 850 different objects to detect and I am thinking using YOLO to solve this problem. but as you know default yolo algorithm works on 80 different objects.
has any one used yolo to detect objects which is number is more than 80? and how did it well?
