Utilizing Generative AI

We are leading the way in rapidly developing generative AI technologies and promoting the creation of an environment in which our employees can utilize them.

We will deploy an AI assistant within the Hitachi Group. This allows users to use a generative AI safely, securely, and at low cost.

By providing functionality that enables users to reference knowledge accumulated throughout the Hitachi Group, we can form a collective set of knowledge and contribute to the creation of better business results.

Actual results from December 2023 to March 2025

As generative AI technology continues to draw global attention, the Hitachi Group is providing an environment where employees can utilize generative AI safely, securely, and at low cost. The AI assistant exclusively for Hitachi Group employees, was used by approximately 60,000 people and reached a total of about 4.27 million chats by the end of March 2024. The AI assistant is equipped with features that allow users to use tools such as automatic translation and automatic creation of meeting minutes at the touch of a button, improving work efficiency and promoting the digitalization of products and services utilizing AI.

Furthermore, in FY 2024, we added a shared knowledge function that organizes and makes accessible common knowledge within the group, a Hitachi dictionary function that interprets Hitachi-specific terms, and an image-file recognition function (multimodal support). These additions aim to promote business utilization and improve convenience.

Going forward, we will continue to deploy the AI assistant to global locations, promote the creation of regional businesses based on the One Hitachi philosophy, and support literacy improvement and increase in Lumada^#2 sales to provide high-quality products and services utilizing generative AI to customers outside the Hitachi Group.

At the employee service desk, we aim to improve employee satisfaction and operator efficiency by utilizing generative AI. We are achieving an increase in self-resolution rates by having generative AI refer to FAQs, specifications, and manuals to present optimal answers to employees.

Furthermore, by having generative AI perform real-time transcription and summarization of the content received by operators over the phone, we achieve reduced response times and improved operational efficiency. By allocating the time saved to supporting more employees, we are also improving the overall satisfaction with the service desk.
