# SO3krates

SO3LR Tauri extends the earlier SO3LR force field from eight elements and 4 million structures to 85 elements and roughly 148 million structures, and rewrites its short-range repulsion, electrostatics and dispersion modules. Keeping the fast SO3krates message-passing backbone, it reproduces nucleobase-pair and protein–ligand interactions and carbohydrate conformer ordering against coupled-cluster references, and yields water and organic-solvent densities, ion hydration and structures of several biomolecular classes in dynamics without system-specific fitting. The models ship in three sizes and scale to the million-atom range on a single GPU.
