Model Overview
Description:
GenMol is a masked diffusion model1 trained on molecular Sequential Attachment-based Fragment Embedding (SAFE) representations2 for fragment-based molecule generation, which can serve as a generalist model for various drug discovery tasks, including De Novo generation, linker design, motif extension, scaffold decoration/morphing, hit generation, and lead optimization.
This model is ready for commercial use.
