## ■ Background of This Update

"Assist AI Chat Bot" is a service that supports the resolution of internal inquiries from employees directed to back-office departments through a conversational AI, replacing human contact persons. It aims to reduce inquiry handling efforts and support knowledge management, thereby facilitating continuous organizational operations.

To date, "Assist AI Chat Bot" has undergone multiple updates aimed at improving response accuracy. This time, to accurately grasp the essential needs of user questions and guide them to solutions, we have implemented AI function agentification and generative AI model upgrades.

With this update, the AI will autonomously collect necessary information from internal manuals and documents in response to user questions, and by asking additional questions as needed, it will grasp essential needs and derive optimal answers. This allows for handling complex inquiries, increasing the number of AI-resolved cases, enhancing user experience, and contributing to the reduction of inquiry handling efforts for administrators.

Our company will continue to optimize back-office operations and improve service value by supporting diverse generative AI models and advancing the enhancement and addition of functions.

## ■ Addition of Other Functions
### Image-based Questions and Interactions Now Possible

We have added a function that allows users to upload image files when asking questions to the AI or escalating questions to administrators. The AI will refer to user text information and images to provide more optimal answers.
