RADCOSMOS conference was largely devoted to many aspects of stellar photospheric modeling, and namely a great success of Ivan's code TLUSTY was emphasized. In this short contribution we focus on models of solar and stellar chromospheres which are not in radiative equilibrium and thus require the knowledge of various nonradiative heating mechanisms. We desrcibe both semiempirical, as well as fully 3D RMHD models and mention the importance of partial redistribution for a proper line diagnostics. Finally, since RADCOSMOS was also covering topic of the polarized line transfer, we present here some of the latests achievements related to the solar chromosphere.
