Multi-modal Foundation Model for Material Design

We propose a multi-modal foundation model for small molecules, a shift from traditional AI models that are tailored for individual tasks and modalities. This model uses a late fusion strategy to align and fuse three distinct modalities: SELFIES, DFT properties, and optical spectrum. The model is pre-trained with over 6 billion samples to provide two primary functions, generating fused feature representations across the three modalities, and cross-modal predictions and genrations. As preliminary experiments, we demonstrate that the fused representation successfully improves the performance of property predictions for chromophore molecules, and showcase 6 distinct cross-modal inferences.
