  An overview of the latest results on the hard probes from the PHENIX
experiment at RHIC is given. The results on the measurements of high $p_{T}$
hadrons, hadron-hadron correlations, open heavy flavor and quarkonia, and
direct photons from large (Au+Au) to small collision systems ($p$+Al and
$p/d/^3$He+Au) provided a deeper insight on the medium created in the large
systems and the possible onset of QGP-nization in transition from small to
large systems.
