Well, you could say that about computers in general. I'm assuming you're referring to temperature (or something similar) which can be set to always pick the most probable token. Floats aside, this should be deterministic. But practically I don't think that changes much since adjusting the input slightly can lead to very different output. Also back in the day the temperature helped it avoid cyclic loops
Yes but chaotic is very different than non deterministic, and not just in an academic way because e.g. I can write tests against chaotic outputs but not really against non deterministic outputs.
