We explore the possible origin of inflation from computable potentials in string theory. The brane-antibrane system provides a particularly interesting system for which we find that inflation is not generic but possible in specific configurations. The corresponding tachyon field allows to end inflation in a brany realization of hybrid inflation. It also provides a natural possibility for initial conditions in terms of a cascade of brane-antibrane systems.
