## Summary

MIT researchers report CheMeleon, an open-source foundation model pre-trained on molecular descriptors of one million PubChem molecules, in the Sept. 14 Journal of Chemical Information and Modeling. The team says it outperformed other foundation and expert-designed models across 58 test cases when few data points are available. Users can download CheMeleon through the open-source ChemProp package and fine-tune it for their own tasks.
