SKT 'A.X K1', 옴니모달로 진화…“소버린 AI 마중물 될 것”

SK Telecom's ultra-large AI model, A.Dot X (A.X) K1, is advancing into an omnimodal model as part of the second phase of its independent AI foundation model project. This upgrade will enable the model to understand and process speech in real time alongside text and images, aiming to establish leadership in sovereign AI. The A.X K1, already a model with approximately 500 billion parameters, will sequentially incorporate multimodal functions, including voice and image recognition.

Professor Kim Geon-hee of Seoul National University highlighted the transition from multimodal models, which integrate text, photos, and videos, to omnimodal models that also include speech understanding. He emphasized the technical difficulty of implementing real-time voice conversations due to their bidirectional and simultaneous nature, requiring the model to handle interruptions, brief feedback, and emotional nuances. Past approaches using separate speech-to-text and text-to-speech systems faced delays and lost key information, such as breathing and emotional signals.

To address these challenges, recent developments focus on integrated language models capable of processing voice information directly. The core strategy involves fine-tuning a powerful pretrained language model using diverse data, including voice, to achieve comprehensive omnimodal capabilities. SK Telecom aims to deploy these advancements across various services like A.Dot, T map, and B tv, and expects the technology to play a central role in enhancing AI applications in gaming and mobility through partners Krafton and 42dot.

Professor Kim stressed that the success of sovereign AI depends heavily on effective use of national core data sovereignty, which includes largely unstructured data in multiple formats. An omnimodal model allows for direct training and operation of such data without relying on external platforms, thus reinforcing both digital sovereignty and sovereignty over physical infrastructure.

South Korean President Lee Jae Myung revealed that North Korea is producing enough nuclear material annually to build 10 to 20 new nuclear weapons, emphasizing the critical need to resume diplomatic talks with Pyongyang to curb its nuclear weapons program. This disclosure, considered rare and based on classified intelligence shared by South Korean and U.S. agencies, highlights North Korea's ongoing expansion of its nuclear arsenal.

North Korea is operating highly enriched uranium production facilities in Yongbyon and Kangson, along with plutonium production at Yongbyon. These facilities can generate dozens of kilograms of nuclear material a year, sufficient for multiple weapons. Estimates from the Korea Institute for Defense Analyses indicate North Korea possessed between 115 and 131 uranium-based weapons and 15 to 19 plutonium-based weapons as of 2025, potentially rising to 216 uranium-based and 27 plutonium-based weapons by 2030, and further increasing through 2040.

President Lee stated that while complete denuclearization is the ideal outcome, the reality suggests North Korea is unlikely to abandon its nuclear program voluntarily. He proposed a practical approach starting with halting North Korea’s nuclear activities, then pursuing gradual reductions, and ultimately aiming for full denuclearization. Lee’s use of the term "disarmament" signals a renewed push to bring North Korea back to negotiations, despite Pyongyang’s firm stance that its nuclear arsenal is non-negotiable and essential for national security.

Victor Cha, a U.S. expert and president of the Geopolitics and Foreign Policy Department at CSIS, proposed the creation of a "collective economic deterrence" pact involving South Korea, the United States, Japan, and other countries to counter China's economic pressure. This proposal comes amid concerns of possible Chinese retaliation toward South Korea following its nuclear-powered submarine project, which the U.S. has approved. The pact aims to collectively respond to any economic coercion by China, similar to the collective security principle of NATO’s Article 5, thereby deterring Chinese economic aggression rather than initiating a trade war.

Cha described China as an unreliable partner for South Korea, accusing Beijing of failing to curb North Korea's nuclear activities and ignoring UN sanctions. He emphasized that no single country in the region can effectively counter China alone, but collectively the countries possess enough leverage. The pact would treat coercion against one member as coercion against all, triggering automatic retaliation, which could impose real costs on Beijing and make it reconsider its pressure tactics.

South Korean President Lee Jae Myung has sought balanced relations with both China and the U.S., exemplified by his recent summit with Chinese President Xi Jinping. However, Cha believes this amicable approach is unlikely to withstand the fallout from the submarine deal, as China has historically retaliated against South Korea economically in response to geopolitical disputes. He called for stronger trilateral cooperation between South Korea, the U.S., and Japan, highlighting their substantial trade with China and leverage over key Chinese imports worth over $23 billion.

Cha urged the Trump administration, which holds the G7 presidency in 2027, to lead efforts in forming this economic deterrence pact and to avoid measures like tariffs on allies. He recommended that Trump explicitly oppose China's economic pressure tactics during his upcoming visit to Beijing in April to deter further coercion against allies, particularly South Korea, following the submarine project agreement.
