Startup Humans& has launched Persimmon, a user simulation model built on NVIDIA's Nemotron 3 Ultra, designed to realistically model how people communicate and interact.
Targeted use cases:
- Agent training: giving AI agents more realistic human counterparts to practice against
- Evaluation: replacing human testers with simulated users to cut evaluation costs
Early observers call it a promising step toward more realistic user simulation.
