SK Telecom will unveil a hyperscale artificial intelligence (AI) model with more than 500 billion parameters at a presentation for the government-led national AI foundation model project on Tuesday. The company said Sunday the SK Telecom consortium, comprising eight organizations including the telecom operator, Krafton, Rebellions, Seoul National University and Korea Advanced Institute of Science and Technology, has developed A.X K1, which will be Korea’s first AI language model with a total of 519 billion parameters. Parameters are learned values that a model uses to analyze data and widely regarded as an indicator of the model’s scale or size. During inference, A.X K1 activates about 33 billion parameters, allowing it to maintain high performance while optimizing computational efficiency. This design enables the model to operate flexibly from heavy-duty training to lightweight task execution. “Developing Korea’s first 500-billion-parameter scale model marks a new turning point for the country’s ambition to join the global top tier of AI leaders amid fierce international compe
