We present preliminary results to determine the strong coupling constant by using the gradient
flow. Pure SU(3) gauge theory is studied. We carry out a direct analysis on very fine zero temperature
lattices where the gradient flow is calculated in the continuum limit. As a second method
we applied the finite-size scaling method to move towards the perturbative regime
