Ok. I see. I guess people are not referring to the raw models themselves when they say non-deterministic, but are also including the harness used in conjunction with the model. Then, in that case, for the exact same input you could get a non-deterministic output. But the model itself and all the mathematical machinery around the model is still very much deterministic.

I guess if we really needed to, we could construct a deterministic agent harness. But in most use cases we probably want some chaotic behavior to increase our chances of stumbling on the desired results.

Thank you for the clarification
