Qwen2.5-1.5B Continually Pretrained on Tibetan

This model is a continual pretraining (CPT) checkpoint built by further pretraining Qwen2.5 1.5B on the Tibetan portion of the MC^2 Corpus.

The model is intended to improve Tibetan language modeling and to support research on low-resource language adaptation.

Training details and methodology are described in: "Efficient Low-Resource Language Adaptation via Multi-Source Dynamic Logit Fusion" (ACL 2026).

Training Data

• Corpus: Tibetan subset of MC^2 Corpus
• Language: Tibetan (bo)
• Training paradigm: Continual pretraining (CPT) starting from Qwen2.5-1.5B

Intended Use

This checkpoint is released primarily for research purposes. Researchers are welcome to use this CPT checkpoint as a base model for future work, particularly in model merging and logit fusion.
