NVIDIA, Rebellions and SK Telecom partner on sovereign AI

Korea's sovereign AI infrastructure is the focus of a new collaboration among NVIDIA, Rebellions and SK Telecom. The companies described an approach that brings together NVIDIA's open infrastructure platform, Rebellions' Korean-designed AI processors, and SK Telecom's AI data center, model and service capabilities.

Korea's Ministry of Science and ICT supports the collaboration, which aims to link domestic semiconductor development with the systems and operational capabilities needed to deliver AI at scale. The work is also intended to support AI services tailored to Korea's language and priorities. SK Telecom plans to offer full-stack sovereign AI, spanning infrastructure, proprietary models and public-facing services, including those under the AI for All project.

Rebellions plans to use NVLink Fusion to connect its Rebel R200 neural processing units to the NVIDIA platform, along with the NVIDIA MGX rack architecture for rack-scale system development. The R200 is being developed for low-latency, energy-efficient inference with frontier models, including multitrillion-parameter mixture-of-experts models. Within a rack, the units connect through NVIDIA NVLink scale-up networking.

The companies outlined an approach to disaggregated inference, in which different stages of AI response generation run on the processor architecture best suited to each task. Planned work includes NVIDIA GPUs for prefill and Rebellions NPUs for decode, aiming to improve inference throughput and power efficiency. The MGX ecosystem gives Rebellions access to an established supply chain of original design manufacturers and component suppliers.

“Korea has the talent, technology and industrial ambition to become a world leader in AI,” said Jensen Huang, founder and CEO of NVIDIA. “Sovereign AI gives nations the power to turn their language, culture and expertise into intelligence.”

“Today’s announcement marks a turning point, opening a new chapter for sovereign AI by connecting Korea’s AI silicon and models with global systems technology,” said Sunghyun Park, cofounder and CEO of Rebellions. Rebellions expects its R200 systems to be ready for deployment in 2028.
