This talk is about the computation ab initio of masses from lattice QCD. In the first part, the light hadron spectrum is computed. Thanks to simulations with $N_f = 2 + 1$ flavors, light hadron masses are extracted and I will show they agree with experiment with a few percent accuracy and all the systematic errors are under control. In the second part, the light quark masses are determinated. We obtain in this work the first full non-perturbative results at the physical point with a high accuracy since we obtain an error of about $5 \%$.
