  We consider intersecting D-brane models which have two dimensional chiral
fermions localized at the intersections. At weak coupling, the interactions of
these fermions are described by generalized Gross-Neveu models. At strong
coupling, these configurations are described by the dynamics of probe D-branes
in a curved background spacetime. We study patterns of dynamical chiral
symmetry breaking in these models at weak and strong coupling, and also discuss
relationships between these two descriptions.
