Abstract
A new generalized ModMax model of nonlinear electrodynamics with four parameters is proposed. The ModMax model and Born--Infeld-type electrodynamics are particular cases of the present model It is shown that a singularity of the electric field at the center of point-like charged particles is absent. We found corrections to Coulomb's law at and obtain the total electrostatic and magnetic energies of point-like charges. Free electric and magnetic charges and their densities are obtained.
