Cohere and LG CNS collaborate on LuckyStar 111B for Korean-English agents

Researchers have developed LuckyStar 111B, a large language model designed for Korean-English enterprise agents, through a collaboration between Cohere and LG CNS. This model builds upon Cohere's Command A model and incorporates techniques like preamble conditioning for efficient tool-use and multilingual adaptation. The adapted model demonstrates improved performance in mathematical reasoning, function calling, and natural-language-to-SQL tasks, while maintaining strong Korean and English instruction-following capabilities. The study also explores methods for efficient scaling, including reinforcement learning and 4-bit quantization for deployment. AI

IMPACT This research offers a practical approach to adapting large language models for multilingual agentic workflows under deployment constraints.

RANK_REASON The cluster describes a research paper detailing a new model adaptation. [lever_c_demoted from research: ic=1 ai=1.0]
