SoftBank Corp. Builds World's Largest
NVIDIA DGX SuperPOD with NVIDIA Blackwell GPUs

SoftBank Corp. (“SoftBank”) announced that on July 22, 2025, it deployed a DGX SuperPOD with DGX B200 systems exceeding 4,000 NVIDIA Blackwell GPUs. This makes SoftBank's AI computing platform currently the world's largest NVIDIA DGX SuperPOD with DGX B200 systems^*1. It is scaled with NVIDIA Quantum-2 InfiniBand networking and supports the NVIDIA AI Enterprise software platform. Furthermore, the AI computing platform built and deployed by SoftBank now exceeds 10,000 GPUs total, delivering a combined computing capability of 13.7 Exaflops^*2.

This AI computing platform will initially be utilized by SB Intuitions Corp. (“SB Intuitions”), SoftBank's subsidiary dedicated to developing homegrown large language models (LLMs) specialized in the Japanese language. SB Intuitions built LLMs with approximately 460 billion parameters in fiscal year 2024 and plans to offer a commercial model, “Sarashina mini,” with 70 billion parameters within fiscal year 2025, which ends on March 31, 2026. By leveraging its newly enhanced AI computing platform and continuously training multiple high-performance Sarashina mini models, SoftBank aims to accelerate the development of even larger and more advanced models.

SoftBank first deployed a DGX SuperPOD equipped with over 2,000 NVIDIA Ampere GPUs in September 2023, delivering 0.7 Exaflops of performance at the time. In October 2024, SoftBank completed a further deployment of over 4,000 NVIDIA Hopper GPUs, expanding performance to 4.7 Exaflops^*3 in total.

SoftBank is committed to building different types of social infrastructure to enable a society that co-exists with AI. The construction of SoftBank's AI computing platform was certified for supply assurance by Japan's Ministry of Economy, Trade and Industry (METI) as a “Cloud Program,” which designates important materials based on its Economic Security Promotion Act^*4. By providing computational resources that can be utilized by a wide range of Generative AI developers, SoftBank will contribute to the establishment of development infrastructure and strengthen the service provision framework in Japan. In addition to utilizing the AI computing platform among its own group companies, SoftBank plans to provide the infrastructure as a service to companies and research institutions in Japan.
