Researchers have developed a general-purpose molecular foundation model, Uni-Mol2, which demonstrates strong transferability across diverse machine olfaction tasks. After fine-tuning on the GS-LF benchmark for odor descriptor prediction, the model achieved state-of-the-art performance and successfully applied its learned representations to cross-dataset odor prediction, odor classification, enantiomer evaluation, and odor mixture discrimination without further deep learning training. The study highlights the advantage of three-dimensional molecular representations over two-dimensional graph models for distinguishing stereoisomers and suggests a "train-once, transfer-across-tasks" paradigm for machine olfaction.
