Think in English, Answer in Korean: Efficient Adaptation of Multilingual Tool-Using Agents

arXiv:2606.31648v1 Announce Type: cross Abstract: We present LuckyStar 111B, a 111B-parameter hybrid reasoning model developed through a collaboration between Cohere and LG CNS for Korean-English enterprise agents under practical memory and serving constraints. The model trains from Cohere's fully post-trained Command A model rather than a new pretraining run, and uses preamble conditioning to switch between concise non-reasoning behavior and longer tool-oriented reasoning. We study four choices for scaling tool-using agents efficiently: multilingual supervised fine-tuning, reinforcement learn

Why this matters
Why now

The increasing demand for practical, efficient, and localized AI solutions is driving collaborations between global AI leaders and national tech players.

Why it’s important

This development indicates a tangible step towards enabling sophisticated, multilingual AI agents within enterprises, particularly in sectors like customer service and global operations.

What changes

The ability to deploy large language models (LLMs) like LuckyStar with efficient adaptation methods and constrained hardware opens new avenues for enterprise AI adoption outside of English-centric environments.

Winners
  • · Cohere
  • · LG CNS
  • · Korean enterprises
  • · AI agent developers
Losers
  • · Monolingual enterprise AI solutions
  • · Companies without access to adapted multilingual models
Second-order effects
Direct

Enterprises can deploy advanced AI agents for multilingual operations more efficiently and cost-effectively.

Second

Increased competition and innovation in localized AI solutions will emerge, particularly in non-English speaking markets.

Third

The proliferation of such agents could lead to enhanced global business communication and reduced language barriers in various industries.
