 # BRAIDBERTa
 
-A RoBERTa-style masked language model pretrained on ZINC 100k, with molecules encoded in
-**BRAID** — a machine-native molecular line notation in which every string decodes to a
-valid molecule.
+BRAIDBERTa is the first pretrained language model for BRAID, a molecular notation in which every valid string decodes to a valid molecule.
 
-BRAIDBERTa exists to answer one question: does a guaranteed-validity notation cost you
-anything on downstream property prediction? Against a matched-budget SMILES control, the
-answer is **no** — the two are statistically indistinguishable on BBBP.
-
-If you want a model whose input notation cannot represent an invalid molecule,
-this is that.
+Compared against a matched SMILES baseline on BBBP, BRAID achieves statistically indistinguishable ROC-AUC while guaranteeing valid decoding.
