The accuracy of current theoretical descriptions of nuclear masses is studied. Ten theoretical models of various kinds are taken for the study: the macroscopic-microscopic, purely microscopic (self-consistent), and models of other natures. Some of them are traditional, but still widely used, while the others are very recent. The most recently evaluated experimental masses of 2012 are taken for the test of the models. Much attention is given to the dependence of the accuracy on the region of nuclei described by the models. The macroscopic-microscopic approaches are still found to be the most accurate in the description of atomic masses. However, the recently developed purely microscopic models (the Hartree-Fock-Bogoliubov approach) reach comparable accuracy. A strong dependence of the accuracy on the region of nuclei described is found, knowledge of which is crucial for a realistic description of specific nuclei.
