# Qwen2.5-1.5B Continually Pretrained on Kazakh (Arabic Script)

This model is a continual pretraining (CPT) checkpoint built by further pretraining Qwen2.5 1.5B on the Kazakh (Arabic Script) portion of the [MC^2 Corpus](https://huggingface.co/datasets/pkupie/mc2_corpus).

The model is intended to improve Kazakh 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"](https://arxiv.org/abs/2604.18106) (ACL 2026).

## Training Data

* **Corpus:** Kazakh subset of MC^2 Corpus
* **Language:** Kazakh (`kk`, Arabic Script) 
* **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.
