# Llama3 8B for Sinhala: 500 target vocabulary size + Align target vocabulary initialization + 2x2LS/MTP/512 training

This model is built on top of Llama3 8B adapted for Sinhala using 30K target language sentences sampled from CC-100.

## Model Details

* **Vocabulary**: This model has an additional 500 target vocabulary.
* **Target vocabulary initialization**: The target weights of the embedding and LM head were initialized using Align initialization.
* **Training**: This model was additionally pre-trained on 30K target language sentences sampled from CC-100. The training was conducted with the 2x2LS/MTP/512 strategies introduced in the paper.

## Model Description

- **Language:** Sinhala
- **License:** Llama 3 Community License Agreement
- **Fine-tuned from model:** meta-llama/Meta-Llama-3-8B
