Imacrea Inc. has begun providing the “exaBase Generative AI Operations Package for Local Governments” to Chuo City, Tokyo, and has officially started operations in the LGWAN environment. As Chuo City promotes the use of generative AI across the entire municipal government, it is focusing not merely on implementation, but on adoption and active use in the workplace. Imacrea will provide end-to-end support including training, help desk services, prompt development assistance, and usage analysis reports, helping municipal staff incorporate generative AI into their daily work. The package supports the essential elements of generative AI operations: adoption and usage promotion. Services include on-demand video training covering the basics of generative AI, prompt design, and RAG usage; a direct help desk where staff can ask questions about exaBase Generative AI operations without going through their department; direct prompt and RAG consultation for advanced needs such as improving response accuracy; business-specific templates such as prompts for preparing assembly responses and documents; regular newsletters with usage tips, case studies from across Japan, and information on new features; and usage analysis reports comparing usage trends with averages from other municipalities, along with recommendations to increase utilization. Key features include LGWAN support for secure use in closed network environments, unlimited account issuance under a fixed monthly fee for government-wide deployment without budget overrun concerns, processing on domestic Japanese servers for handling confidential information, standard access to unlimited-use language models to encourage active AI use by all staff, and unlimited RAG creation to flexibly build and provide department-specific AI tools. Some language models have limits on input and output character counts. A free trial with unlimited account issuance is also available. Details, including how to apply for the trial, can be request
