Overview

NLLB-200-1.3B fine-tuned on 11 Northeast Indian languages paired with English. Extended vocabulary: 256,212 tokens (8 custom lang tags added).

This Checkpoint

CP2 — retrain after critical tokenization bug fix (run 1 used batch["src_lang"][0] instead of per-sample src_lang)
Trained: 60,000 steps | Effective batch: 96 | bf16
mni_Mtei excluded (Meitei Mayek script unsupported by NLLB subword vocab)
Best val loss: ~2.245 (plateaued at step ~26k)

Karbi (1,745 train pairs) and Tangsa (4,875) severely data-starved
