Slow-roll inflation successfully provides the initial conditions of the Universe on scales observed by cosmic microwave background measurements and large scale structure surveys. We will discuss the initial conditions predicted by beyond slow-roll inflation models, such as small-scale curvature perturbations that seed the formation of primordial black holes and give rise to parity-violating four-point correlation functions, chiral gravitational waves at pulsar-timing-array, LISA, and LIGO-Virgo-KAGRA sensitivities, and helical primordial magnetic fields.
