At the recent "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 launched the new medical-specific large model Baichuan-M4 and the AI family doctor product "Bai Xiao Yi". This launch marks Baichuan Intelligence's deep implementation in the healthcare sector, aiming to address the industry's pain points of "abundant consultation but insufficient accessibility" in AI healthcare.
1. Baichuan-M4: Ranking First on Authoritative Medical Lists, Hallucination Rate Reduced to 3.3%
To address the three major shortcomings of general large models in medical scenarios—severe hallucinations, poor evidence-based reasoning capabilities, and poor questioning skills—Baichuan-M4 has achieved comprehensive performance improvements through fundamental technological innovations:
World-Leading Performance: In the three authoritative medical lists—HealthBench, HealthBench Hard, and HealthBench Professional—Baichuan-M4 ranked first globally, surpassing mainstream general models such as GPT-5.5 and Opus4.7.
Low Hallucination Assurance: Relying on Baichuan's original "Fact-Aware Reinforcement Learning Algorithm," the factuality hallucination rate of the bare model of Baichuan-M4 was reduced to 3.3%, significantly enhancing the safety and credibility of medical consultations.
Clinical Deep Collaboration: Currently, Baichuan Intelligence has already collaborated with three top national hospitals, including Beijing Children's Hospital, Cancer Hospital of the Chinese Academy of Medical Sciences, and Ruijin Hospital Affiliated with the School of Medicine of Shanghai Jiao Tong University, to conduct joint clinical research, promoting the transition of large models from laboratories to real-world diagnosis and treatment frontlines.
2. Bai Xiao Yi: The "Family Health Manager" Based on the WeChat Ecosystem
Wang Xiaochuan proposed that "the brain solves the capability issue, while the body solves the accessibility issue." As the "body" connecting patients with medical resources, the AI family doctor "Bai Xiao Yi" has a clear positioning:
Accessibility and Companion: "Bai Xiao Yi" operates within the enterprise WeChat ecosystem (Bai Xiao Yi @ Baichuan Family Doctor). After users add it to their family group, it can serve as a "new family member" to provide real-time companionship.
Full Life Cycle Management: It automatically creates independent health records for family members, capturing and structuring user's physical condition, medication history, and examination data during daily conversations.
Proactive Health Intervention: Unlike passive "question-and-answer robots," Bai Xiao Yi has proactive identification capabilities, able to敏锐ly detect high-risk health signals from daily chats in the family group and proactively remind users to re-consult or take medicine on time.
3. Industry Insights: AI Healthcare Enters the "Precision Operation" Era
In the forum, Wang Xiaochuan candidly stated that although the scale of general large models in medical consultation was large last year, user feedback was not ideal. The core contradiction in the healthcare industry lies in the insufficient supply of high-quality resources. Therefore, the premise of AI healthcare development is not simply "replacing doctors," but finding the right "product form":
From Consultation to Management: Through Bai Xiao Yi, AI has upgraded from a simple "question-and-answer device" to a "general practitioner" covering pre-visit preparation, post-visit follow-up, and long-term health record management.
Building a New Four-Level Medical Care Model: Baichuan Intelligence aims to build a coordinated mechanism from the family level to primary hospitals, and then to top national hospitals by opening up AI capabilities, truly achieving the popularization of high-quality medical resources.
