The A.X 3.1 model is part of SK Telecom's dual-track strategy for LLM capabilities. While the A.X 4 series focuses on optimizing large-scale models for the Korean business environment, the A.X 3 series represents a sovereign AI model developed entirely in-house, emphasizing self-sufficiency. The A.X 4 series leverages large-scale continual pre-training (CPT) with Korean data to enhance performance in Korean language processing.
In the Massive Multitask Language Understanding in Korean (KMMLU) benchmark, the A.X 3.1 model achieved approximately 88% performance compared to the benchmark score of A.X 4.0 standard, which was 78.3%. In the Cultural and Linguistic Intelligence in Korea (CLIcK) benchmark, A.X 3.1 demonstrated performance of approximately 90% compared to the benchmark score of A.X 4.0 standard, which was 85.7%.
This strategic release by SK Telecom underscores the company's commitment to advancing AI capabilities in the Korean market. By providing access to these models, SK Telecom aims to foster innovation and collaboration within the AI community.
