Model Card for Model ID

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
