본 기술 보고서는 LG AI 연구에서 개발한 대규모 다국어 언어 모델인 K-EXAONE을 소개합니다. K-EXAONE은 2360억 개의 총 파라미터로 구성된 Mixture-of-Experts 아키텍처를 기반으로 하며, 추론 시에는 230억 개의 파라미터를 활성화합니다. 이 모델은 256K 토큰의 컨텍스트 윈도우를 지원하며, 한국어, 영어, 스페인어, 독일어, 일본어, 베트남어의 6개 언어를 지원합니다. 저희는 추론, 에이전트 기능, 일반적인 능력, 한국어 능력 및 다국어 능력을 포괄하는 광범위한 벤치마크를 통해 K-EXAONE을 평가했습니다. 이러한 평가에서 K-EXAONE은 유사한 규모의 공개 모델과 비교하여 경쟁력 있는 성능을 보여줍니다. 더 나은 삶을 위한 AI 발전에 기여하고자 설계된 K-EXAONE은 다양한 산업 및 연구 분야에 적용될 수 있는 강력한 독점 AI 기반 모델입니다.

Original Abstract

This technical report presents K-EXAONE, a large-scale multilingual language model developed by LG AI Research. K-EXAONE is built on a Mixture-of-Experts architecture with 236B total parameters, activating 23B parameters during inference. It supports a 256K-token context window and covers six languages: Korean, English, Spanish, German, Japanese, and Vietnamese. We evaluate K-EXAONE on a comprehensive benchmark suite spanning reasoning, agentic, general, Korean, and multilingual abilities. Across these evaluations, K-EXAONE demonstrates performance comparable to open-weight models of similar size. K-EXAONE, designed to advance AI for a better life, is positioned as a powerful proprietary AI foundation model for a wide range of industrial and research applications.
