Yerevan State University researchers worked with YerevaNN on Chemlactica and Chemma, language models for molecular generation, property prediction and optimization. The research used a corpus of 110 million molecules with computed properties, totaling 40 billion tokens. A genetic algorithm incorporates the models to optimize molecular properties.
The research paper documents training Chemma-2B on Nebius.ai cloud for 488 H100 GPU hours and Chemlactica-1.3B for 288 H100 GPU hours. Chemlactica-125M was trained locally at Yerevan State University for 306 A100 hours. The authors acknowledge Nebius.ai for granting GPU cloud access and providing support. Training used PyTorch Fully Sharded Data Parallel and Flash Attention.
Nebius describes three Nebius-based molecular models presented by researchers from YerevaNN and Yerevan State University. The models were continuously pre-trained on 110 million molecules with computed properties totaling 40 billion tokens and integrated into a genetic algorithm for molecular optimization.
