  We present the general discussion on the inflection point inflation with
small or large inflaton fields and show the effects of reheating dynamics on
the inflationary predictions. In order to compare the model predictions with
precisely measured CMB anisotropies and constrain the inflation models, the
knowledge of the reheating dynamics is required. Inflection point inflation
extended to the trans-Planckian regime can accommodate a sizable
tensor-to-scalar ratio at the detectable level in the future CMB experiments.
