GMO Prime Strategy Co., Ltd. (President and CEO: Tadashi Yoshimasa, Head Office: Chiyoda-ku, Tokyo, hereinafter "GMO Prime Strategy"), a member of the GMO Internet Group, will begin offering the Enterprise edition of "GMO AI RAG," a RAG (Retrieval-Augmented Generation) software for corporations that instantly generates answers based on internal documents, starting Tuesday, June 30, 2026. An open-source version is also scheduled for release around Autumn 2026. "GMO AI RAG" supports operation not only in cloud environments but also in on-premise/local environments, enabling the construction of a secure, custom AI knowledge base environment at low cost while minimizing information leakage risks. The Enterprise edition includes paid options and support services to enhance usability, maintainability, and performance.
