We consider the inflation models where the string axions play the role of the inflaton. The simple two-field case is not sufficient to solve many cosmological problems, but with a large enough number of fields we can remove this difficulty. The mass distribution of the fields in this case is of crucial importance for observations and dynamics after inflation.
