**Llama3.1-Typhoon2-8B**: Thai Large Language Model (Instruct)

**Llama3.1-Typhoon2-8B** is a pretrained only Thai 🇹🇭 large language model with 8 billion parameters, and it is based on Llama3.1-8B.


For technical-report. please see our [arxiv](https://arxiv.org/abs/2412.13702).
*To acknowledge Meta's effort in creating the foundation model and to comply with the license, we explicitly include "llama-3.1" in the model name.

## **Model Description**

- **Model type**: A 8B decoder-only model based on Llama architecture.
- **Requirement**: transformers 4.45.0 or newer.
- **Primary Language(s)**: Thai 🇹🇭 and English 🇬🇧
- **License**: [Llama 3.1 Community License](https://github.com/meta-llama/llama-models/blob/main/models/llama3_1/LICENSE)


## **Intended Uses & Limitations**

This model is a pretrained base model. Thus, it may not be able to follow human instructions without using one/few-shot learning or instruction fine-tuning. The model does not have any moderation mechanisms, and may generate harmful or inappropriate responses.
