  We provide the latest constraints on the power spectra of both scalar and
tensor perturbations from the CMB data (including \textit{Planck}~2015, BICEP2
\& \textit{Keck Array} experiments) and the new BAO scales from SDSS-III BOSS
observation. We find that the inflation model with a convex potential is not
favored and both the inflation model with a monomial potential and the natural
inflation model are marginally disfavored at around $95\%$ confidence level.
But both the Brane inflation model and the Starobinsky inflation model fit the
data quite well.
