# Llama 3.1 8B Instruct for Telugu: ElChat (No Copy)

This model is built on top of Llama 3.1 8B Instruct adapted for Telugu using 500M target language tokens sampled from MADLAD-400. It has an additional target vocabulary of 10K. The model was trained using the ElChat method without special token weight copying.

## 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.
* **Post-processing**: The model was post-processed using the ElChat method without special token weight copying.


## Model Description
