  We summarize the results obtained for the quark masses (u,d,s,c, and b) in
Refs.~\cite{AlamKhan:2023ili,AlamKhan:2023kgs} and strong coupling ($\alpha_s$)
using renormalization group (RG) improvement of the theoretical expressions and
experimental inputs that enter in the QCD sum rules. We obtain $m_{u}(2
GeV)=2.00_{-0.40}^{+0.33}$ MeV, $m_{d}(2 GeV)=4.21_{-0.45}^{+0.48}$ MeV, and
$m_{s}(2 GeV)=104.34_{-4.24}^{+4.32}$ MeV using Borel Laplace sum rules for the
divergence of the axial vector currents. The relativistic sum rules for the
moments of the heavy quark currents lead to the determination of
$\alpha_s(M_Z)=0.1171(7)$, $\overline{m}_{c}=1281.1(3.8)$ MeV and
$\overline{m}_{b}=4174.3(9.5)$ MeV.
