In a recent paper we presented pop-cosmos, a state-of-the-art stellar population synthesis (SPS) framework. We described the details of how we fitted this framework to a large, deep, flux-limited (r < 25) sample of galaxies from the Cosmic Evolution Survey (COSMOS), enabling investigation of the full web of dependencies between different galaxy properties for the first time. In this talk I will present my recent work investigating the star formation histories (SFHs) of galaxy populations up to z=4 utilising the pop-cosmos model. I will begin by summarizing the details of our model and the SFH prescription employed in it. I will then present key galaxy evolution results such as the mean stellar mass assembly histories of galaxy populations through cosmic time. Further, by defining star-forming and quiescent subpopulations based on recent star formation activity (i.e. last 100 Myr), these relations will highlight how these subpopulations build up their stellar mass.
