# Llama3 8B CPT SEA-LIONv2

SEA-LION is a collection of Large Language Models (LLMs) which has been pretrained and instruct-tuned for the Southeast Asia (SEA) region.
This is the card for the Llama3 8B CPT SEA-LIONv2 base model which has undergone continued pre-training from the [Meta-Llama-3-8B-Instruct](https://huggingface.co/meta-llama/Meta-Llama-3-8B-Instruct) model.

SEA-LION stands for <i>Southeast Asian Languages In One Network</i>.


## Model Details

### Model Description

The continued pre-training data for Llama3 8B CPT SEA-LIONv2 base model encompasses approximately 48B tokens.

- **Developed by:** Products Pillar, AI Singapore
- **Funded by:** Singapore NRF
- **Model type:** Decoder
- **Languages:** English, Indonesian, Thai, Vietnamese, Tamil
- **License:** [Llama3 Community License](https://huggingface.co/meta-llama/Meta-Llama-3-8B/blob/main/LICENSE)

For tokenization, the model employs the default tokenizer used in Meta-Llama-3-8B-Instruct.

### Benchmark Performance
We evaluated Llama3 8B CPT SEA-LIONv2 base model on general language capabilities.

#### General Language Capabilities
For the evaluation of general language capabilities in SEA languages, we employed the [BHASA evaluation benchmark](https://arxiv.org/abs/2309.06085v2) across a variety of tasks.
These tasks include Question Answering (QA), Sentiment Analysis (Sentiment), Toxicity Detection (Toxicity), Translation in both directions (Eng>Lang & Lang>Eng), Abstractive Summarization (Summ), Causal Reasoning (Causal) and Natural Language Inference (NLI).

The evaluation was done **five-shot** with native prompts and only a sample of 100-1000 instances for each dataset was used as per the setting described in the paper.
