What is Orb-v3 / OrbMol-v2?

Orb-v3 and OrbMol-v2 are machine-learning interatomic potential models, neural networks trained to predict the forces and energies between atoms so that materials and molecules can be simulated without solving quantum-mechanical equations directly at every step. Orb-v3 is built for simulating solid-state materials while OrbMol-v2 extends the same underlying approach to molecular systems, letting both share a common modeling framework across different classes of matter.
