In this work, a numerical study of the $\alpha$–Starobinsky inflationary model. For an appropriate choice of parameters, it reproduces the standard Starobinsky limit. We compute numerically the scalar and tensor power spectra over the parameter space and evaluate the associated inflationary observables. Finally, we provide a comparative analysis in the $(n_S,A_S)$ parameter space, presented via a contour plot. Our results indicate that, for certain choices of parameters, the $\alpha$-Starobinsky model is favored by recent observations.
