They don’t need to be dererministic, only reproducible.

They’re not reproducible, nor are they even reliable right now.

I don't think there's a meaningful difference between "deterministic" and "reproducible" the way you just used them. How can something be reproducible if you can't accurately predict what it will do?

Regardless, you can make them deterministic by turning the temperature down to zero. Just nobody likes doing that for whatever reason. I guess it ruins some sort of illusion people seem to like.
