We consider the predictions of the Quark-Gluon String Model (QGSM) and of the Lund Model algorithm (PYTHIA) for the inclusive spectra and multiplicity distributions of different secondary hadrons produced in pp (or ppBAR) collisions in the energy interval square-root s = 62 GeV divided-by 200 TeV. Both models describe reasonably well the existing experimental data, however their predictions for the case of very high energies are different. We discuss the possible reasons for these differences.
