We present systematic study of the Gauged Nambu–Jona–Lasinio model in the DSB regime. The principle of selection for 4-fermion models as a low-energy approximation of QCD it is given. On their basis are considered a possibility an intrinsic stability such models with a finite cutoff $\Lambda$. In the framework of our approach we have found the role of the effects of the gluon condensate on the parameters of the effective chiral Lagrangian in a low-energy region.
