SMolLM: Small Language Models Learn Small Molecular Grammar
Researchers have developed SMolLM, a 53K-parameter weight-shared transformer model capable of generating novel SMILES with 95% validity on the ZINC-250K drug-like-molecule benchmark, outperforming a standard GPT model with ten times more parameters. The model's mechanism involves resolving SMILES constraints in a fixed hierarchy, demonstrating a compact and interpretable approach to molecular generation.
