  The spherical model is a popular solvable model and has been applied to
describe several critical phenomena such as the ferromagnetic transition,
Bose-Einstein condensation, spin-glass transition, glass transition, jamming
transition, and so on. Motivated by recent developments of active matter, here
we consider the spherical model driven by the Ornstein-Uhlenbeck type
self-propulsion force with persistent time $\tau_p$. We show that the model
exhibits the Ising universality for finite $\tau_p$. On the contrary, the model
exhibits the random field Ising universality in the limit $\tau_p\to\infty$.
