At the same time, the energy landscapes need to be accurately mapped, as small errors in barriers can lead to large deviations in reaction probabilities. This brings a particularly interesting challenge for machine learning interatomic potentials, which are becoming well-established tools to accelerate molecular dynamics simulations. We compare state-of-the-art machine learning interatomic potentials with a particular focus on their inference performance on CPUs and suitability for high throughput simulation of reactive chemistry at surfaces. The considered models include polarizable atom interaction neural networks (PaiNN), recursively embedded atom neural networks (REANN), the MACE equivariant graph neural network, and atomic cluster expansion potentials (ACE) . The models are applied to a dataset on reactive molecular hydrogen scattering on low-index surface facets of copper. All models are assessed for their accuracy","cbCaiiYzjPbJveYf","https://ap.wps.com/l/cbCaiiYzjPbJveYf","pdf",1535625,7,1,18,"English","en",105,"# Abstract\n# Introduction\n## Benchmarking approach\n## Models and dataset\n## Evaluation metrics\n# Results\n## Accuracy and inference performance\n## Reactive sticking probabilities\n# Conclusion","[{\"question\":\"Why is benchmarking ML interatomic potentials important for reactive gas–surface dynamics?\",\"answer\":\"Gas–surface reaction predictions need very large ensemble averages and highly accurate energy landscapes; even small barrier errors can cause large deviations.
