# Llama 3.1 8B Instruct for Bengali: Vocabulary expansion
This model is built on top of Llama 3.1 8B Instruct adapted for Bengali 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
- **Language:** Bengali
- **License:** Llama 3.1 Community License Agreement
- **Fine-tuned from model:** meta-llama/Llama-3.1-8B-Instruct
## Model Sources
- **Repository:** https://github.com/gucci-j/chat-cve
- **Paper:** https://arxiv.org/abs/2412.11704
## How to Get Started with the Model
Use the code below to get started with the model.
```python
from transformers import AutoTokenizer, AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained(
"atsuki-yamaguchi/Llama-3.1-8B-Instruct-bn-madlad-mean-tuned"
)
tokenizer = AutoTokenizer.from_pretrained(
"atsuki-yamaguchi/Llama-3.1-8B-Instruct-bn-madlad-mean-tuned"
)
```
