• Example Input:

  <task>
  Translate the source sentence from English to 한국어.
  Be sure to reflect the guidelines below when translating.
  </task>
  
  <instruction>
  - Translate without any condition.
  </instruction>
  
  <translation>
  <source><English>
  New era, same empire. T1 is your 2024 Worlds champion!
  </English></source>
  <target><한국어>
  

• Expected Output:

  새로운 시대, 여전한 왕조. 티원이 2024 월즈의 챔피언입니다!
  </한국어></target>
  </translation>
  

  Model will generate the XML end tags.

Training

• Trained with LoRA adapter
  • PLM: bfloat16
  • Adapter: bfloat16
  • Adapted to all the linear layers (around 2.05%)

Usage (IMPORTANT)

• Should remove the EOS token at the end of the prompt.
