SeaLLMs/SeaLLMs-v3-1.5B

SeaLLMs-v3 - Large Language Models for Southeast Asia

Website    Model    🤗 DEMO    Github    [NEW] Technical Report

We introduce SeaLLMs-v3, the latest series of the SeaLLMs (Large Language Models for Southeast Asian languages) family. It achieves state-of-the-art performance among models with similar sizes, excelling across a diverse array of tasks such as world knowledge, mathematical reasoning, translation, and instruction following. In the meantime, it was specifically enhanced to be more trustworthy, exhibiting reduced hallucination and providing safe responses, particularly in queries closed related to Southeast Asian culture.

🔥 Highlights

• State-of-the-art performance compared to open-source models of similar sizes, evaluated across various dimensions such as human exam questions, instruction-following, mathematics, and translation.
• Significantly enhanced instruction-following capability, especially in multi-turn settings.
• Ensures safety in usage with significantly reduced instances of hallucination and sensitivity to local contexts.

Uses

SeaLLMs is tailored for handling a wide range of languages spoken in the SEA region, including English, Chinese, Indonesian, Vietnamese, Thai, Tagalog, Malay, Burmese, Khmer, Lao, Tamil, and Javanese.

This page introduces the SeaLLMs-v3-1.5B model, which can be easily fine-tuned for your specific downstream tasks, especially in SEA languages. Note that this is a base model, if you are looking for a model that can be directly applicable to your downstream applications, you may want to check the chat version model: SeaLLMs-v3-1.5B-Chat.

Evaluation

Evaluation

We evaluate SeaLLMs-v3-1.5B mainly using human exam questions.

Multilingual World Knowledge - M3Exam

M3Exam consists of local exam questions collected from each country. It reflects the model's world knowledge (e.g., with language or social science subjects) and reasoning abilities (e.g., with mathematics or natural science subjects).

Multilingual World Knowledge - MMLU

MMLU questions are translated to SEA languages for evaluation, which primarily tests the cross-lingual alignment of the model as the required knowledge is still mainly Western-focused.
