# Qwen2.5 7B for Tamil: Continual pre-training only

This model is built on top of Qwen2.5 7B adapted for Tamil using 500M target language tokens sampled from MADLAD-400.

## Model Details

* **Vocabulary**: This model has no additional target vocabulary. It retains the original vocabulary of Qwen2.5 7B.
* **Training**: This model was continually pre-trained on 500M target language tokens sampled from MADLAD-400.


## Model Description

- **Language:** Tamil
- **License:** Apache 2.0
- **Fine-tuned from model:** Qwen/Qwen2.5-7B
