# Qwen2.5 7B Instruct for Telugu: Vocabulary expansion

This model is built on top of Qwen2.5 7B Instruct adapted for Telugu using 500M target language tokens sampled from MADLAD-400. It has an additional target vocabulary of 10K.

## Model Details

* **Vocabulary**: This model has an additional target vocabulary of 10K.
* **Target vocabulary initialization**: The target weights of the embedding and LM head were initialized using mean initialization.
* **Training**: This model was continually pre-trained on 500M target language tokens sampled from MADLAD-400.


## Model Description
