Abstract: In this talk, the latest measurements of $|V_{cb}|$ and $|V_{ub}|$ 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 $|V_{cb}|$ by determining the < q$^2$ > moments of $B → X_clν$.
