The collaboration will integrate Korean-designed R200 processors with NVIDIA's NVLink Fusion and MGX rack architecture for AI deployment.
NVIDIA, Rebellions and SK Telecom announced a collaboration to advance Korea’s sovereign AI infrastructure — using NVIDIA NVLink Fusion to bring together NVIDIA’s open infrastructure platform, Rebellions’ Korean-designed AI processors and SK Telecom’s AI data center, model and service capabilities.
As part of the agreement, Rebellions will use NVLink Fusion to connect its Rebel R200 neural processing units (NPUs) to the NVIDIA platform, and harness the NVIDIA MGX rack architecture for rack-scale system development. SK Telecom plans to deploy these systems, drawing on its AI data center operations expertise, proprietary models and services.
Supported by Korea’s Ministry of Science and ICT (MSIT), the collaboration aims to support AI services tailored to Korea’s language, industries and priorities, connecting Korean semiconductor development with the systems and operational capabilities needed to deliver AI at scale.
Scaling silicon innovation with NVIDIA’s open infrastructure platform
NVLink Fusion extends NVIDIA’s vertically integrated, horizontally open AI platform to custom XPUs. It enables chipmakers to combine specialized silicon with NVIDIA’s high-bandwidth, low-latency scale-up networking and established infrastructure ecosystem, helping improve performance, reduce deployment risk and accelerate time to market.
Rebellions is developing its next-generation R200 NPU, optimized for low-latency and energy-efficient inference using frontier models, including multitrillion-parameter mixture-of-experts models. Through NVLink Fusion, Rebellions will connect its R200 NPUs within a rack through NVIDIA NVLink scale-up networking.
The NVIDIA MGX rack architecture and reference designs will support development of the systems, while the MGX ecosystem gives Rebellions access to an established supply chain of original design manufacturers and component suppliers.
Connecting infrastructure, models and services
SK Telecom brings experience building and operating AI data centers, alongside its proprietary foundation models and public-facing AI services. Building on its long-standing collaboration with NVIDIA in AI development and sovereign infrastructure, SK Telecom plans to connect these capabilities and deploy them in its AI data center using the standardized MGX rack architecture to deliver full-stack sovereign AI.
The MGX rack architecture provides a foundation for GPU and NPU systems to share data center design elements, including rack footprint, power delivery and cooling. This approach can support infrastructure planning alongside Rebellions’ processor and system development.
The companies plan to develop an approach to disaggregated inference, assigning different stages of AI response generation to the processor architecture best suited to each task. Their planned work includes using NVIDIA GPUs for prefill and Rebellions NPUs for decode to improve inference throughput and power efficiency.
SK Telecom plans to connect this infrastructure with its proprietary foundation models and public-facing services, including those under the government’s AI for All project, to advance its full-stack sovereign AI strategy.
Supporting sovereign AI infrastructure with NVLink Fusion
MSIT is supporting collaboration between NVIDIA and Korean NPU companies, beginning with Rebellions and SK Telecom, to strengthen Korea’s sovereign AI infrastructure.
By connecting Korean-developed processors and models with NVIDIA infrastructure and SK Telecom’s data center expertise, the companies aim to establish a foundation for sovereign AI services across Korea’s public and private sectors.
Availability
Rebellions’ R200 systems are expected to be ready for deployment in 2028.
