SB C&S to Begin Offering Sparticle's On-Premises Generative AI Environment 'GBase on Spark' for Secure Enterprise Use of Confidential Data

Sparticle Inc. (Headquarters: Chuo-ku, Tokyo; Representative Director: Tatsuya Kaneda, hereinafter 'Sparticle') and SB C&S Co., Ltd. (Headquarters: Minato-ku, Tokyo; President and CEO: Kazuya Kusukawa, hereinafter 'SB C&S') will begin offering the on-premises LLM platform 'GBase on Spark' on June 10, 2026. This platform enables secure use of generative AI without transmitting corporate confidential data to external environments.

As the business application of generative AI rapidly expands, companies are increasingly exploring its use in diverse areas such as knowledge retrieval, document creation, data analysis, and software development support. However, concerns about sending sensitive or internal data to external cloud environments have driven growing demand for generative AI solutions that prioritize security and governance. As a result, interest in on-premises AI platforms—capable of developing and operating large language models (LLMs) while securely managing internal data—has intensified.

'GBase on Spark,' now offered by SB C&S, is a solution combining Sparticle’s on-premises generative AI LLM package 'GBase On-premises' with NVIDIA’s AI infrastructure 'NVIDIA DGX™ Spark' and other compatible systems. It enables the development and operation of large language models on high-performance GPU infrastructure while ensuring corporate data remains within the organization, creating a secure AI utilization environment. Leveraging proprietary RAG technology and customizable LLMs, it allows businesses to build generative AI environments optimized for their specific operational needs. Furthermore, its multimodal capabilities—supporting not only text but also images and PDFs—make it applicable across a wide range of industries, including local governments, educational institutions, manufacturing, construction, and service sectors.

Moving forward, Sparticle and SB C&S will continue to support enterprise AI adoption by providing advanced AI infrastructure and solutions, contributing to the enhancement of Japanese companies’ competitiveness.
