AI semiconductor startup Rebellion announced on the 16th that it will supply more than 100 of its RebelRacks, equipped with its own NPU (neural processing unit), to a Tokyo data center in collaboration with Japanese AI infrastructure company ai&.
ai&, which has signed an agreement with Rebellion, is a company that builds and operates data centers based on heterogeneous AI infrastructure composed of various types of semiconductors. Through this agreement, ai& will utilize Rebellion's RebelRacks in its currently under-construction data center. ai& plans to build five new data centers in Japan by the end of this year and expand them into a total 40MW-scale infrastructure by 2027.
The confirmed supply volume and contract period remain undisclosed. However, Rebellion emphasized that it plans to supply more than 100 units starting with the initial batch. Both Rebellion and ai& utilize open-source technical specifications, enabling rapid deployment without large-scale configuration changes.
Rebellion plans to officially target Japan's sovereign AI market starting with this supply. Last March, Rebellion established its first overseas subsidiary in Tokyo and has been securing local market footholds through proof-of-concept (PoC) projects with cloud service providers (CSPs), telecommunications companies, and others.
David Bennett, co-founder and CEO of ai&, stated, "Heterogeneous infrastructure means using the hardware best suited for each task, and Rebellion is the most fitting partner for such infrastructure. With Rebellion's high efficiency, we can design more flexible service cost structures while fully leveraging open-source frameworks."
Park Sung-hyun, CEO of Rebellion, said, "Through this collaboration, Rebellion will secure direct touchpoints with local Japanese customers and expand its business foundation in Japan's AI infrastructure market. We will provide more efficient inference infrastructure to Japanese companies, the government, and developers."
