$\mathrm{D_s^+/D^+}$ production yield ratio measured in pp collisions at midrapidity $(\lvert y\rvert<0.5)$ at $\sqrt{s}=13.6$ TeV as a function of the charged-particle multiplicity per unity of pseudorapidity ($\langle\mathrm{d}N_\mathrm{ch}/\mathrm{d}\eta\rangle$) and $\pt$ compared to predictions obtained with different PYTHIA 8 tunes and EPOS4HQ predictions in both pp and $\mathrm{Pb-Pb}$ collisions. The results obtained by the ALICE Collaboration in $\mathrm{Pb-Pb}$ collisions at $\sqrt{s_\mathrm{NN}}=5.02$ TeV are also reported.
