# Description
1. LLM 번역 응답 크기 소프트코딩화
2. LLM도 DOM파서를 통한 문장 단위 및 병렬 번역을 하도록 수정
3. 바깥쪽 태그가 제대로 제거가 안되는 문제 해결
4. 추가적으로, 기본 번역 프롬프트를 ```You are a translator. Translate the following
html or text into {{slot}}. Do not output anything other than the
translation, punctuations and quotation marks.```으로 변경하고 싶습니다.
------
1. Softcoded LLM translation response size
2. Modified LLM to also do sentence-by-sentence and parallel translation
via DOM parser
3. Fixed an issue with outer tags not being removed properly
4. Additionally, I want to change the default translation prompt to
```You are a translator. Translate the following html or text into
{{slot}}. Do not output anything other than the translation,
punctuations and quotation marks.```
