After the Planck 2015 results, which remain consistent with some of the simplest single-field models of inflation, one may ask whether there remains any motivation to consider inflationary models with multiple light fields. I discuss this question, and present one way of answering it by performing a Bayesian model comparison between the curvaton scenario (which has two fields and at least four free parameters) and simpler single-field scenarios. I also show an application to one of the cosmological anomalies, the dipolar power asymmetry observed in the CMB temperature.
