+# RiemannGen checkpoints
+
+Trained checkpoints for the [RiemannGen](https://github.com/) project: two
+from-scratch MolMIM-style latent sequence models.
+
+- `atom/final-atom.pt` + `atom/vocab_new.txt` -- plain-SMILES model, trained
+  on a combined ZINC15 + MOSES + ChEMBL corpus.
+- `fragment/final.pt` + `fragment/vocab_new.txt` -- SAFE-fragment-encoded
+  model, for scaffold growth / local fragment editing.
+
+Licensed under MIT -- free to use, modify, and redistribute.
+
+Note: the training corpus includes data from ChEMBL, which is distributed
+under CC-BY-SA. Whether that imposes any share-alike obligation on model
+weights trained on it is an unsettled question in ML licensing generally --
+not resolved here, mentioned for transparency.
