SK Telecom is no longer content just connecting phone calls. The South Korean telecom giant launched “Haein,” a sovereign AI infrastructure platform integrating over 1,000 Nvidia Blackwell GPUs, making it one of the largest GPU clusters in the country.
The platform, which went live on August 5, 2025, offers GPU-as-a-Service and has been selected to support South Korea’s national AI foundation model program.
What Haein actually does
At its core, Haein handles both training and inference, the two most compute-hungry tasks in the AI stack.
SKT partnered with VAST Data to implement what VAST calls its “AI Operating System,” software specifically tailored for Nvidia Blackwell infrastructures. Supermicro also contributed to the hardware optimization. The partnership, announced on August 14, 2025, focuses on improving virtualization and data pipeline performance for multi-tenant setups.
