  We calculate the anomalous dimensions of higher-spin currents, both singlet
and non-singlet, in the Gross-Neveu model at the $1/n^2$ order. It was
conjectured that in the critical regime this model is dual to a higher-spin
gauge theory on $AdS_4$. The $AdS/CFT$ correspondence predicts that the masses
of higher-spin fields correspond to the scaling dimensions of the singlet
currents in the Gross-Neveu model.
