Abstract: Grids of stellar atmosphere models and associated synthetic spectra arenumerical products which have a large impact in astronomy due to theirubiquitous application in the interpretation of radiation from individual starsand stellar populations. 3D model atmospheres are now on the verge of becominggenerally available for a wide range of stellar atmospheric parameters. Wereport on efforts to develop a grid of 3D model atmospheres for late-type starswithin the CIFIST Team at Paris Observatory. The substantial demands incomputational and human labor for the model production and post-processingrender this apparently mundane task a challenging logistic exercise. At themoment the CIFIST grid comprises 77 3D model atmospheres with emphasis ondwarfs of solar and sub-solar metallicities. While the model production isstill ongoing, first applications are already worked upon by the CIFIST Teamand collaborators.
