I would argue with your definition of hallucination here. It's just a value judgement we humans apply to output that does not correspond to reality in some way that we don't find useful.

We can control how diverse or creative output is via temperature. I am assuming that these new models could work at higher temperatures (i.e. more creative) while maintaining factual accuracy for things you care about. Or alternatively, keep the same temperature but have far fewer hallucinations (i.e. wrong answers).
