At the "New Paradigm of AI in Healthcare" academic forum held at the Baichuan Building of Tsinghua University, Wang Xiaochuan, founder and CEO of Baichuan Intelligence, officially unveiled the new generation medical large model "Baichuan-M4" and the AI family doctor "Bai Xiaoyi" that is about to be released. The launch of this model marks a breakthrough in the accuracy and application form of AI technology in the medical field.

Top Three Authoritative Lists, Solving the Medical Hallucination Issue

In the field of medical AI, the "nonsense" (factual hallucinations) of large models has always been a core challenge preventing their clinical application. To address this, Baichuan Intelligence developed an original "factual perception reinforcement learning algorithm," successfully reducing the factual hallucination rate of the bare model of Baichuan-M4 to 3.3%.

With this technological breakthrough, Baichuan-M4 ranks first in the three authoritative medical lists: HealthBench, HealthBench Hard, and HealthBench Professional. Its comprehensive medical capabilities have surpassed mainstream flagship large models such as GPT-5.5, Opus 4.7, and DeepSeek-V4-Pro. Currently, Baichuan Intelligence has collaborated with three top hospitals in China, including Beijing Children's Hospital, Chinese Academy of Medical Sciences Cancer Hospital, and Ruijin Hospital Affiliated with Shanghai Jiao Tong University School of Medicine, for related clinical research.

Building an Intelligent Family Doctor Based on the WeChat Ecosystem

Regarding the core issue of insufficient supply of high-quality medical resources in China, Wang Xiaochuan emphasized that large models not only need to solve the "brain power," but also achieve "physical access" through appropriate product forms. The AI family doctor "Bai Xiaoyi" built based on this concept focuses on the core positioning of "clearly seeing the doctor,安心 managing the family."

In practical applications, "Bai Xiaoyi" will be deeply integrated into the WeChat ecosystem. Users just need to add the enterprise WeChat "Bai Xiaoyi@Baichuan Family Doctor" and include it in the family group. The system will automatically create independent health records for each family member. It can capture and structure the physical condition, medication history, and test data of family members during daily conversations, identify high-risk health signals in casual chats, and proactively provide reminders for follow-up visits and medication.
