A number of non-LTE model atmospheres for hot stars are developed, which do not have the artificial division of earlier models between the hydrostatic photosphere and the supersonic stellar wind envolope. The only parameters needed in these models are the stellar effective temperature, gravity, and radius, defined at the inner atmospheric boundary. The models yield stellar energy distributions and hydrogen and helium line spectra. Calculations and results are presented for the O4f star Zeta Puppis, together with a sequence of models for Central Stars of Planetary Nebulae.
