     An obvious difference between plateau-like models like this and the simplest inflationary models, like ${\displaystyle V(\phi )=\lambda \phi ^{4}}$, is that the simplest models require only one parameter and absolutely no tuning of parameters to obtain 60 or more e-folds of inflation, while the plateau-like models require three or more parameters and must be fine-tuned to obtain even a minimal amount of inflation.
