  We describe how monomial chaotic inflation becomes compatible with the latest
CMB data thanks to radiative corrections producing a plateau. The interactions
of the inflation with other fields, required for reheating, can flatten the
potential and moderate the production of primordial gravitational waves,
keeping these below the current upper bound. We show that the appearance of a
plateau requires that the inflaton couples to fermions and to another scalar or
a gauge group. We give concrete examples of minimal particle physics models
leading to plateaus for quadratic and quartic chaotic inflation. We also
provide a three-parameter model-independent description of radiatively
corrected inflation that is amenable to CMB analyses.
