In this talk, the latest measurements of |Vub | and |Vcb | by the Belle II collaboration are presented. These results are based on 189 fb−1 of Belle II data recorded at the Υ(4S) resonance. We report measurements with inclusive and exclusive B decays. Two main strategies are employed for these results, one where the other B in the event is exclusively reconstructed (tagged) and another where the other B is not (untagged). We also report on a novel approach to measuring inclusive |Vcb | by determining the < q2 > moments of B → Xclν.
