Abstract

I discuss the basic model of Higgs inflation, with a large non-minimal curvature coupling, from the point of view of effective field theory. It is pointed out that the effective cutoff scale is uncomfortably low compared to the inflation scale, thus rendering these models extremely sensitive to the details of the ultraviolet completion.
