๐Ÿ”ฌ The paper represents a paradigm shift by combining machine-learned interatomic potentials (MLIPs) with generative modeling to bypass traditional conformer generation, achieving both higher accuracy and greater efficiency than existing methods. Free & open source:.

โšก Our LoQI #GenAI model generates accurate molecular 3D structures in a single shot, finding the lowest energy conformers for molecules without expensive conformer search. It correctly handles stereochemistry and works on complex molecules like macrocycles! ๐Ÿ’Š #compchem

The model's computational efficiency makes it well-suited for exploring vast chemical spaces to identify promising candidates for polymerization catalysts, radical initiators, or novel materials with tailored properties. Coupling AIMNet2-NSE with active learning and automated.

We also introduced BASChem19 benchmark- a dataset for evaluating computational chemistry methods on industrially significant reactions. What makes these reactions particularly valuable to the chemical industry is their direct application in producing commercially important
