The One AITech Co., Ltd. focuses on the application of AI technology in healthcare and diverse industries, launching conversational AI products such as TaiOne Care GPT, building an AI ecosystem, and providing integrated consulting services to help enterprises accelerate digital transformation. Post-pandemic, Taiwan's medical workforce has generally experienced "high burnout and low efficiency" issues. Therefore, HIS Copilot and the Ward Round Integration System were developed as clinical auxiliary AI digital assistants to help medical staff solve practical problems in real-time during their daily work. These two medical applications within TaiOne Care GPT initially used cloud-based large language models. However, as many medical institutions currently require private deployment, The One AITech Co., Ltd. also utilizes two open-source models, Llama-4 and Phi-4, for post-training, providing them to these institutions for on-premises or private cloud deployment. During the implementation process, relevant regulations are strictly followed to safeguard information security and patient safety requirements. In addition, the interface design of the HIS Copilot system closely aligns with original localized HIS operating habits. Through a one-click transfer to the data middle platform for AI processing, the data is then sent back to the hospital's HIS system in the format required by each hospital, eliminating the need to change interfaces or relearn, thereby ensuring smooth implementation and high usage rates. Meanwhile, the Ward Round Integration System adopts a collaborative model of "user as developer," allowing various professional roles—such as physicians, nurses, nutritionists, and health educators—to build their own exclusive AI assistants, making it Taiwan's first cross-professional AI collaborative information platform.
