NVIDIA Partners with Rebellions and SK Telecom to Integrate Custom NPUs into MGX Rack Systems
NVIDIA announces a collaboration with Korean chipmaker Rebellions and SK Telecom to use NVLink Fusion to integrate R200 NPUs into MGX racks, supporting sovereign AI infrastructure and disaggregated inference.
NVIDIA, Korean AI chip developer Rebellions, and SK Telecom announced a partnership on November 10, 2026, to develop sovereign AI infrastructure that combines locally designed processors with NVIDIA’s NVLink Fusion interconnect technology. Under the agreement, Rebellions’ next-generation R200 neural processing units (NPUs) will be integrated into NVIDIA’s MGX rack architecture, with deployment planned at SK Telecom’s AI data centers.
The core of this collaboration lies in achieving heterogeneous computing interconnection through NVLink Fusion. Rebellions plans to use this technology to connect its R200 NPUs via high-bandwidth, low-latency networking, targeting energy-efficient inference for frontier AI models, including multitrillion-parameter mixture-of-experts architectures. NVIDIA’s MGX rack architecture will provide standardized system designs, while its ecosystem of original design manufacturers and component suppliers could help Rebellions accelerate development and reduce deployment complexity.
The companies also plan to explore disaggregated inference, splitting AI workloads between different processor architectures. Under the proposed approach, NVIDIA GPUs would handle the compute-intensive prefill stage, while Rebellions NPUs would manage token generation during decoding. This division of labor is intended to improve inference throughput and power efficiency, potentially addressing two major challenges facing AI data center operators.
SK Telecom plans to deploy these systems within its AI data center infrastructure, connecting the hardware with proprietary foundation models, including A.X K2, and public-facing AI services. The initiative supports Korea’s government-backed “AI for All” project and aims to strengthen domestic control over AI infrastructure, models, and services. Korea’s Ministry of Science and ICT is supporting the collaboration as part of a broader effort to strengthen the country’s sovereign AI capabilities and domestic semiconductor industry.
