KoSafeGuard 8B

🔔 Update: 더 작고 뛰어난 성능의 모델을 학습했습니다: iknow-lab/llama-3.2-3B-wildguard-ko-2410

KoSafeGuard는 언어모델이 생성한 텍스트의 유해성을 판별해주는 모델입니다. 이 모델을 활용하여 유해한 발언이 없는 안전한 챗봇을 구축할 수 있습니다. 이 모델은 번역된 데이터셋(heegyu/PKU-SafeRLHF-ko)으로 학습되었으며, 다음과 같은 카테고리의 위험성을 찾아낼 수 있습니다.

• 자해, 폭력, 범죄, 개인정보 유출, 약물 및 무기
• 혐오 표현, 아동 범죄, 성적 컨텐츠
• 기타 다양한 비윤리적 행위
