Rebellions unveiled the plan at Nvidia AI Day Seoul 2026 at COEX in southern Seoul. Its R200 neural processing unit (NPU) will link to Nvidia systems through NVLink Fusion and anchor rack-scale inference systems built on Nvidia's MGX server rack design.
SK Telecom will put the systems to work in live environments, drawing on its AI data center operations and in-house models.
The partners will also divide inference into stages, leaving the compute-heavy prefill stage to Nvidia GPUs and handing the token by token decode stage to Rebellions' more power-efficient NPUs.
The setup, known as disaggregated inference, is designed to raise throughput and power efficiency at once and drive down total cost of ownership.
The alliance, backed by the Ministry of Science and ICT, aims to build what the partners call a "Sovereign AI Token Factory" serving the Korean language, local data and industry-specific demand.
Rebellions aims to deploy R200 systems in 2028. The chip is being tuned for low-latency inference on frontier AI models, including mixture-of-experts models with trillions of parameters, and NVLink Fusion will wire the NPUs in each rack directly into Nvidia's high-speed scale-up network.
"This announcement is an important turning point in expanding South Korea's sovereign AI ecosystem," Rebellions CEO Park Sung-hyun said, adding that the company would help Korean-made technology "grow into a core pillar that drives the world's AI."
Deepu Talla, Nvidia's vice president of robotics and edge AI, opened the event earlier in the day by casting Korea as a central player in physical AI over the next decade.
He pointed to Hyundai Motor Group's virtual factories and a Doosan robot being trained in Nvidia simulation software to polish car door surfaces.
