Small molecule Models

Small-molecule foundation models learn representations of chemical structure from large libraries of molecules, supporting property prediction, de novo generation, and drug–target interaction modeling. By capturing the grammar of chemistry — bonds, scaffolds, and physicochemical properties — these models accelerate hit discovery, lead optimization, and the design of novel compounds. They underpin modern computational drug discovery, bridging molecular representation and the biological targets these molecules act on.
