> You’d expect the same answer each time. It’s the same photo, the same model, the same question. But you won’t get the same answer. Not even close — and the differences are large enough to cause a hypoglycaemic emergency.

Already the first paragraph highlights the issue; unless you set temperature=0.0 and the model can actually do reproducible inference, none of the "answers" you get are deterministic!

But it's a very common misconception that "same question gets same answer" would be true, when it's almost by accident you get the same answer for the same question. The part that people expect this, is the problem, as most platforms are not built to provide that experience. Of course you'd get different responses, it's on purpose!
