t5-base-korean-chit-chat

This model is a fine-tuning of paust/pko-t5-base model using AIHUB "한국어 SNS". This model infers the next conversation by using the conversation used on social media..

이 모델은 paust/pko-t5-large model을 AIHUB "한국어 SNS"를 이용하여 fine tunning 한 것입니다. 이 모델은 SNS상에서 사용되는 대화를 이용하여 다음 대화를 추론 합니다.
