KAIST Korean enterprise LLM benchmark finds Korean-native models outperform English-primary models by 15–40% on professional legal, finance, and medical tasks. Gives APAC CIOs evidence that Korean-specific evaluation is required for Korean-language enterprise AI procurement.
Korea Advanced Institute of Science and Technology (KAIST) has released a comprehensive benchmark evaluating large language model performance on Korean-language enterprise tasks across three professional domains: legal (contract analysis, regulatory interpretation, case summarisation), financial (earnings report analysis, regulatory filing review, investment memorandum drafting), and medical (clinical note summarisation, drug interaction analysis, patient communication drafting).
The benchmark evaluates GPT-4, Claude 3.5 Sonnet, Gemini Pro, and NAVER HyperCLOVA X — the four models most commonly evaluated for Korean enterprise deployment. Key findings: Korean-native HyperCLOVA X outperforms English-primary models on specialised professional Korean tasks by 15–40% depending on domain, with the largest gap in legal Korean (40%) and smallest in general business writing (15%). GPT-4 and Claude 3.5 perform comparably on general Korean tasks but diverge on highly specialised professional vocabulary. The benchmark provides Korean enterprise CIOs, legal teams, and finance leaders with evidence-based guidance for Korean-language AI model selection — moving beyond general-purpose benchmark claims to task-specific professional performance evidence.
