  Inflation creates perturbations for the large scale structures in the
universe, but it also dilutes everything. Therefore it is pertinent that the
end of inflation must explain how to excite the Standard Model {\it dof} along
with the dark matter. In this paper we will briefly discuss the role of visible
sector inflaton candidates which are embedded within the Minimal Supersymmetric
Standard Model (MSSM) and discuss their merit on how well they match the
current data from the Planck. Since the inflaton carries the Standard Model
charges their decay naturally produces all the relevant {\it dof} with no {\it
dark/hidden sector radiation} and no isocurvature fluctuations. We will first
discuss a single supersymmetric flat direction model of inflation and
demonstrate what parameter space is allowed by the Planck and the LHC. We will
also consider where the perturbations are created by another light field which
decays after inflation, known as a {\it curvaton}. The late decay of the
curvaton can create observable non-Gaussianity. In the end we will discuss the
role of a {\it spectator} field whose origin may not lie within the visible
sector physics, but its sheer presence during inflation can still create all
the perturbations responsible for the large scale structures including possible
non-Gaussianity, while the inflaton is embedded within the visible sector which
creates all the relevant matter including dark matter, but no dark radiation.
