South Korea is emerging as a significant player in the field of large language models (LLMs), thanks to a combination of government support, corporate innovation, and academic research. This strategic focus not only aims to reduce reliance on foreign technologies but also enhances data privacy and fosters advancements in critical sectors such as healthcare, education, and telecommunications.
Government Initiatives for Sovereign AI
In 2025, the South Korean government launched a substantial initiative, investing 240 billion won to develop sovereign LLMs. This program selected five leading consortia, including Naver Cloud and SK Telecom, to create models that can operate on local infrastructure. This move is designed to ensure that the country can maintain control over its AI technologies and data.
Additionally, the Ministry of Food and Drug Safety introduced groundbreaking guidelines for the approval of text-generating medical AI, marking a significant milestone as the first framework of its kind globally.
Corporate and Academic Innovations
Several companies and institutions are making strides in the development of LLMs tailored for the Korean language:
- SK Telecom’s AX 3.1 Lite: This model, with 7 billion parameters, was trained on 1.65 trillion multilingual tokens, focusing heavily on Korean. It achieves impressive performance metrics, scoring around 96% on the KMMLU2 benchmark for Korean language reasoning.
- Naver’s HyperClova X Think: Released in June 2025, this model enhances search and conversational capabilities specifically for Korean users.
- Upstage’s Solar Pro 2: This model is notable for being the only Korean entry on the Frontier LM Intelligence leaderboard, showcasing its efficiency in matching the performance of larger international models.
- LG AI Research’s Exaone 4.0: Launched in July 2025, this model is designed with 30 billion parameters and competes well in global benchmarks.
- Seoul National University Hospital’s Medical LLM: This innovative model was trained on 38 million de-identified clinical records and scored 86.2% on the Korean Medical Licensing Examination, outperforming the human average.
Moreover, collaborations such as Mathpresso and Upstage’s MATH GPT have resulted in a 13 billion-parameter model that excels in mathematical benchmarks, outperforming even GPT-4 while using fewer computational resources.
Technical Trends and Market Outlook
Korean developers are focusing on efficiency, optimizing token-to-parameter ratios to create models that can compete with larger Western counterparts. This trend is evident in the development of domain-specific models that yield superior results in targeted areas, such as the medical LLM from Seoul National University Hospital.
The South Korean LLM market is projected to grow significantly, from 182.4 million USD in 2024 to 1,278.3 million USD by 2030, reflecting a compound annual growth rate of 39.4%. This growth is driven by the increasing demand for chatbots, virtual assistants, and sentiment analysis tools. Telecom companies are also integrating edge-computing LLMs to enhance data security and reduce latency.
Key South Korean LLMs
