Bllossom | Demo | Homepage |

The Bllossom language model is a Korean-English bilingual language model based on the open-source LLama3. It enhances the connection of knowledge between Korean and English. It has the following features:

Knowledge Linking: Linking Korean and English knowledge through additional training
Vocabulary Expansion: Expansion of Korean vocabulary to enhance Korean expressiveness.
Instruction Tuning: Tuning using custom-made instruction following data specialized for Korean language and Korean culture
Human Feedback: DPO has been applied
Vision-Language Alignment: Aligning the vision transformer with this language model

This model devel by MLPLab at Seoultech, Teddysum and Yonsei Univ
