TMTPOST -- The "Zijing AI Doctor" system developed by Zijing Zhikang was officially launched on Wednesday, marking the debut of 42 AI doctors from 21 different departments. Each department has selected common diseases, with a focus on over ten conditions, to build diverse synthetic patient data that aids in the AI doctors' evolution. The system currently covers more than 300 diseases. The system is now open for testing AI doctors' diagnostic capabilities, with future plans to include tests for treatment and conversation abilities. It is expected to be officially available to the public in the first half of 2025. Zijing Zhikang, a company founded in September 2024, is incubated by Tsinghua University's Intelligent Industry Research Institute (AIR), under the leadership of Zhang Yaqin. Its goal is to implement the "Agent Hospital" concept, using AI to offer affordable, convenient, and high-quality medical services to the public.
