Fujitsu and Sony Bank partner to integrate generative AI into core banking system design and development

"Our goal is to deliver new value to our customers through technological innovation. We are excited to embark on this collaboration with Fujitsu, integrating generative AI into our core banking system development. This partnership isn't just about efficiency and quality; it's about unlocking more flexible and agile services for our customers. Merging our cloud-native environment with cutting-edge AI marks a significant leap forward in redefining the future of financial services."

"Building on the successful delivery of the next-generation digital banking system in May, Fujitsu is proud to partner with Sony Bank on a strategic initiative that will apply generative AI to innovate system development. This undertaking marks the official launch of our vision for a truly AI-driven development ecosystem, centered on generative AI. By integrating Fujitsu's AI expertise and business knowledge into Sony Bank's operational core banking solution, we expect to significantly accelerate their development and service delivery."

First, Sony Bank and Fujitsu will apply generative AI to the development and testing phases of core banking systems. The partners will leverage Fujitsu's proprietary knowledge graph-enhanced RAG technology, which refines generative AI input data by linking large dataset relationships, to improve AI accuracy. Future plans include expanding consistent generative AI-driven development across all processes – from management and requirements definition to operation and maintenance – with an expected 20% reduction in development times. By completing all processes entirely on AWS, the initiative will achieve advanced scalability, security, and significantly enhanced development efficiency. This will foster a robust development ecosystem through the maximization of Fujitsu's core banking solution benefits and AWS integration for continuous quality improvement and rapid development cycles.

Moving forward, Sony Bank will fully leverage the cloud-native characteristics of its new core banking system to accelerate development efficiency, enhance quality, and swiftly deliver new products and services by integrating various external services and adopting new technologies.
Through the provision of its core banking solution, Fujitsu will continue to promote its financial industry-focused initiatives with Uvance. In this way, Fujitsu aims to enhance business operations for financial institutions and contribute to the realization of a more prosperous society.
