Humansand introduced Persimmon, billed as the first large-scale model designed to realistically simulate how people talk and interact.
A widely-shared take from daumiller explains why this matters: anyone building frontier LLMs knows you can't create high-quality data for arbitrary long-horizon tasks without either sacrificing speed & money (humans) or quality — realistic conversation simulation targets exactly that bottleneck.
