PHYSIX OBSERVATION

Hy4 had to be scaled up one day after launch because its quota was snapped up, showing that user demand for domestic Agent models is real. More noteworthy is its cost efficiency: at the same score, its price is an order of magnitude lower than competitors, which may force open-source model competition to shift from chasing benchmark scores to chasing cost-performance, and expand the choices available to small and mid-sized developers.
