Rebellions, SK Telecom and Arm Partner to Build Sovereign AI Infrastructure
Collaboration targets high-performance, energy-efficient AI data centres for telecom and public sector markets.
Rebellions, a global leader in AI inference infrastructure, announces a collaboration with SK Telecom (SKT) and Arm to develop AI inference infrastructure designed to support sovereign AI and telecommunications-focused AI data centres. Through this collaboration, the companies plan to develop an AI server combining Arm AGI CPU, the first Arm-designed data centre CPU, with Rebellion’s AI chips. The system will be validated in SKT’s AI data centre environment before expanding to global markets.
This alliance, featuring industry leaders from each AI infrastructure field, aims to address the surging demand in the inference market and set standards for high-performance, energy-efficient sovereign AI infrastructure. Together, the companies plan to collaborate across the value chain from infrastructure design through real-world deployment and validation.
As part of the initiative, the Arm AGI CPU, built on Arm® Neoverse® CSS V3, and Rebellion’s RebelCard™ accelerator, will be combined into high-performance server infrastructure. Beyond hardware integration, the partners will co-develop the entire software stack, including firmware, and deploy the developed solutions in SKT’s live data centre environments to verify performance and stability for sovereign AI models and telco-specific large-scale data processing. There are plans to review running SKT’s proprietary foundation model, A.X K1, on these servers.
Following technical validation, the partners plan to explore broader commercial deployment opportunities. Through this, Rebellions intends to supply optimised solutions for the global Sovereign AI data centre market and secure a strong presence, particularly in Asia. Specifically, the focus will be on supplying customised, stability-proven solutions to global telecommunications companies and public sectors that require independent AI infrastructure.
“By providing our ‘RebelCard’—which offers overwhelming performance and power efficiency—alongside our full-stack software, Rebellions has become a core pillar supporting next-generation AI data centres,” says Jinwook Oh, CTO of Rebellions. “We expect this ‘one-team’ collaboration of experts to serve as a significant precedent in the industry for building AI-specialised infrastructure.”
“By providing a full package that combines inference-optimised infrastructure with our proprietary foundation model, A.X K1, we will further strengthen our competitiveness in the AI data centre market,” says Jaeshin Lee, Vice President and Head of AI Business Development at SK Telecom.
“As AI infrastructure expands globally, CPUs play a critical role in coordinating workloads across accelerators, memory and networking,” said Eddie Ramirez, vice president of go-to-market, Cloud AI Business Unit at Arm. “Arm AGI CPU, built on Arm Neoverse CSS V3, was designed to deliver the performance and efficiency required for large-scale AI deployments. Together with Rebellions and SK Telecom, we’re enabling scalable infrastructure for sovereign AI and telecommunications markets.”
