SB C&S to Handle Sparticle's On-Premises Generative AI Environment "GBase on Spark" for Secure Data Utilization

Sparticle, Inc. (Headquarters: Chuo-ku, Tokyo; Representative Director: Tatsuya Kaneda; hereinafter "Sparticle") and SB C&S Corporation (Headquarters: Minato-ku, Tokyo; President and CEO: Kazuya Kusakawa; hereinafter "SB C&S") will commence handling "GBase on Spark," an on-premises LLM foundation that enables secure utilization of generative AI without transmitting confidential data externally, on June 10, 2026.

The business application of generative AI is rapidly expanding, with companies considering its introduction for diverse purposes such as knowledge search, document creation, data analysis, and software development support. On the other hand, concerns about transmitting confidential or internal company data to external cloud environments are growing, leading to an increased need for generative AI utilization that emphasizes security and governance. Consequently, interest is rising in on-premises AI foundations that allow for the development and operation of Large Language Models (LLMs) while securely handling internal data.

"GBase on Spark," which SB C&S will handle, is a solution that combines Sparticle's LLM package for on-premises generative AI utilization, "GBase On-premises," with NVIDIA's AI infrastructure "NVIDIA DGX™ Spark" and other compatible products. It enables the development and operation of Large Language Models (LLMs) on a high-performance GPU infrastructure while realizing a secure AI utilization environment that does not transmit corporate data externally. With its proprietary RAG technology and customizable LLMs, it allows for the construction of generative AI environments optimized for each company's business requirements. Furthermore, its multimodal support, capable of handling various data formats including text, images, and PDFs, makes it applicable across a wide range of industries such as local governments, educational institutions, manufacturing, construction, and service industries.

Moving forward, Sparticle and SB C&S will continue to support corporate AI utilization and contribute to strengthening the competitiveness of Japanese companies by providing advanced AI infrastructure and solutions.
