Humansand launches Persimmon, first large-scale model simulating how real humans behave
gharik · x · 2026-09-11
Startup Humansand introduced Persimmon, billed as the first large-scale model designed to realistically simulate how real people talk and interact across people, contexts, and time.
The company's premise: for AI to collaborate with humans, it must first understand them. Investors at Felicis publicly backed the thesis, calling models that understand people the next frontier.
Potential use cases include social simulation, user research, and agent collaboration testing — though the launch is based on official claims, with no independent evaluations yet.
