 which is executed element-wise and subsequently summed over the different chemical species. More details on the accuracy of the MACE models can be found in @Maes2024. Fig. \ref{fig:int4} shows the abundance profiles of seven chemical species, where the full curves indicate the MACE test of model *int4* from @Maes2024, and the dashed curves give the result for the classical model. On average, the MACE routine provides a speed-up of a factor 26, not taking into account the potential extra speed-up factor due to efficient vectorisation when coupling MACE with an SPH hydrodynamical model.
