Checkpoints of a dialogue-level encoder trained over frozen dialog2flow-joint-bert-base turn embeddings, continued-pretrained sequentially over large conversational corpora (see the d2f-turn-embeddings-* datasets on this profile). One subfolder per stage; each contains the best checkpoint, its training log and config. Research artifact; documentation forthcoming.

xlc-s2 — the final model of the chain. It has seen the full curriculum (~26M turns) and is the recommended checkpoint. The intermediate stages are released for research on continued-pretraining dynamics:
