We study the atypically large deviations of the height at the origin at late times in (1 + 1)-dimensional growth models belonging to the Kardar-Parisi-Zhang (KPZ) universality class. We present exact results for the rate functions for the discrete single-step growth model, as well as for the continuum KPZ equation in a droplet geometry. Based on our exact calculation of the rate functions we argue that models in the KPZ class undergo a third-order phase transition from a strong-coupling to a weak-coupling phase, at late times.
