This model is a multilingual translation model fine-tuned on LLaMA 3.1 Instruct base model. It enables mutual translation between the following Southeast Asian languages:

Korean
Vietnamese
Indonesian
Cambodian (Khmer)
Thai

Model Details

The model is designed for translating short text segments between any pair of the supported languages.

Supported language pairs:

Korean ↔ Vietnamese
Korean ↔ Indonesian
Korean ↔ Cambodian
Korean ↔ Thai
Vietnamese ↔ Indonesian
Vietnamese ↔ Cambodian
Vietnamese ↔ Thai
Indonesian ↔ Cambodian
Indonesian ↔ Thai
Cambodian ↔ Thai

Model Description

This model is specifically optimized for Southeast Asian language translation needs, focusing on enabling communication between these specific language communities.

The extensive training data of 20M examples (1M for each translation direction) provides a robust foundation for handling common expressions and basic conversations across these languages.

Model Architecture

Base Model: meta-llama/Llama-3.1-8B-Instruct

Bias, Risks, and Limitations

Performance is limited to short sentences and phrases
May not handle complex or lengthy text effectively
Translation quality may vary depending on language pair and content complexity
