The claim is that merging internal representations from separate models, such as one for proteins and one for small molecules, can capture these interactions with a much smaller feature set. If it holds, interaction prediction for virtual screening could need less computing and data representation, and could generalise better.","findings":["Composing biochemical language models performs similar or better than standard methods for representing molecular interactions.","The composed approach does this with significantly fewer features.","The authors propose that future work build biochemical foundation models that jointly encode diverse molecular modalities."],"terms":[{"term":"composing biochemical language models","means":"Merging the internal representations from separate language models, each trained on a different type of biological data, to describe a molecular complex."},{"term":"features","means":"The numerical values that describe a molecule or complex and are given to a prediction model as input."},{"term":"molecular interactions","means":"The ways molecules such as a drug and its protein target contact and affect each other, which determine binding strength and specificity."}],"basis":"abstract","abstractFrom":"europepmc","model":"claude-sonnet-5-5","writtenAt":"2026-10-13T13:46:15.593Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-13T13:46:15.593Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
