Llama-SEA-LION-v2-8B
SEA-LION is a collection of Large Language Models (LLMs) which have been pretrained and instruct-tuned for the Southeast Asia (SEA) region.
Llama-SEA-LION-v2-8B is a multilingual model which has undergone continued pre-training on approximately 48B tokens across 5 SEA languages: English, Indonesia, Tamil, Thai and Vietnamese.
SEA-LION stands for Southeast Asian Languages In One Network.

Model Details
Model Description
We performed continued pre-training in English and SEA languages on Meta-Llama-3-8B-Instruct, a decoder model using the Llama 3 architecture, to create Llama-SEA-LION-v2-8B.
For tokenisation, the model employs the default tokenizer used in Llama 3 8B Instruct.
Benchmark Performance
We evaluated Llama-SEA-LION-v2-8B on general language capabilities.
General Language Capabilities
For the evaluation of general language capabilities in SEA languages, we employed the BHASA evaluation benchmark 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.
