| contents | We present the predictions of various observables for strange ($\mathrm{K}^{0}_{\mathrm S}$, $Λ$($\overlineΛ$)) and multi-strange hadrons ($Ξ^-$($\overlineΞ^+$), $ϕ$, and $Ω^-$($\overlineΩ^+$)) using the recently updated 3+1D hydrodynamics-based EPOS4 framework and AMPT model. In this study, we report the transverse momentum (${p_{\rm T}}$) spectra, particle yields (${\mathrm{d}N/\mathrm{d}y}$), and ${p_{\rm T}}$ integrated yield ratios relative to pions for $O+O$ collisions at $\sqrt{s_{\mathrm{NN}}}=7$~TeV. The results reveal that there are indications of stronger radial flow in EPOS4 compared to AMPT. We observe a final state multiplicity overlap with small ($p+p$ and $p+Pb$) and large ($Pb+Pb$) collision systems. |
