The recent observation of the 750 GeV diphoton excess at 13 TeV LHC hasmotivated many scenarios of physics beyond the Standard Model. In this work, webegin by showing that many models which explain the observed excess tend to getstrongly coupled well below the Planck scale. We then study a simple scenarioinvolving colored vector-like fermions with exotic charges, which is expectedto stay weakly coupled till the Planck scale. We find the conditions underwhich this happens, derive the Renormalization Group equations for such modelsand solve them to show that perturbativity till Planck scale can be maintainedfor a very reasonable choice of parameters. Finally, we discuss issues relatedto vacuum stability and the possibility of inflation in the scenarios we study.
