GRB 080319B was a very bright gamma-ray burst with a total isotropic energy ~1054 erg. It was also distinguished by the strong prompt optical emission with a peak magnitude ~5th. In this work we interpret the prompt optical (soft γ-ray) emission as the synchrotron (synchrotron self-Compton) radiation of internal shocks at a rather large radius ~1016 cm. In this model, the GRB outflow is baryonic rather than Poynting-flux dominated. The 2nd-order Inverse Compton radiation of the internal shocks may have not been effectively suppressed and a GeV-TeV flare as energetic as the keV-MeV emission is plausible, which is detectable by a satellite like GLAST or AGILE.
