Futang Baichuan - A large pediatric model jointly launched by Baichuan Intelligent and Beijing Children's Hospital.

What is Futang Baichuan?

Futang Baichuan is the world's first comprehensive pediatric model, jointly released by the National Children's Medical Center, Beijing Children's Hospital affiliated with Capital Medical University, Baichuan Intelligence, and Xiaofang Health. It covers a three-dimensional knowledge system encompassing common and complex childhood diseases, possesses powerful pediatric clinical reasoning capabilities, and pioneers an "evidence-based model" for pediatrics. Like a professional pediatrician, it integrates the best medical evidence to develop scientific and personalized treatment plans for children. The model is based on trillions of tokens of professional medical data, encompassing comprehensive medical knowledge including professional medical papers, guidelines, textbooks, and books in both Chinese and English. It integrates the clinical experience of over 300 renowned pediatric experts from Beijing Children's Hospital and decades of anonymized, high-quality medical record data.

Based on the model, two AI pediatric doctor applications, "Futang Baichuan" and "Expert Version," have been launched. The grassroots version is designed for routine pediatric disease diagnosis and treatment scenarios, and its diagnostic capabilities have reached the level of attending physicians at Beijing Children's Hospital, helping to improve the pediatric diagnosis and treatment skills of grassroots doctors. The expert version focuses on the diagnosis and treatment of difficult and rare pediatric diseases and was launched at Beijing Children's Hospital in February 2025, with a 95% consistency rate between treatment plans and expert consultation results.

The main functions of Futang Baichuan

• Three-dimensional knowledge systemCovering common and complex childhood illnesses. Integrating comprehensive medical knowledge from professional medical papers, guidelines, textbooks, and books in both Chinese and English. It incorporates the clinical experience of over 300 renowned pediatric experts from Beijing Children's Hospital and decades of high-quality, anonymized medical record data.
• Pediatric clinical reasoning abilityThey can integrate the best medical evidence like a professional pediatrician, developing scientific and personalized treatment plans for children. They strengthen skills in evidence-based medicine, reasoning, memory, dialogue, and multimodal communication.
• Evidence-based model in pediatricsIt pioneered the "evidence-based model" in pediatrics, providing reasoned and well-founded answers by presenting facts and explaining the logic. It has built its own highly reliable evidence-based medicine knowledge base, containing over 40,000 guidelines and expert consensus documents in Chinese and English, over 38 million research papers, and nearly 170,000 drug instructions.
• Multiple rounds of consultations and communicationWhen facing patients' parents, the system can independently conduct multiple rounds of consultations and patiently communicate with them. Through the disease inquiry function, it can form a preliminary diagnosis and provide examination suggestions.

The technical principles of Futang Baichuan

• Artificial intelligence technologyThe "Futang Baichuan" pediatric big data model utilizes the latest artificial intelligence technologies, including Natural Language Processing (NLP) and Machine Learning (ML). This enables the model to understand and process natural language data, learning from it and extracting useful information. The model also possesses powerful pediatric clinical reasoning capabilities, integrating the best medical evidence like a professional pediatrician.
• Data sourceThe model's data sources are very extensive and authoritative, including:
  • Chinese and English professional medical papersIt covers authoritative pediatric clinical guidelines and research literature from both domestic and international sources.
  • Medical Guidelines and TextbooksIt includes standard treatment guidelines and textbooks in the field of pediatrics.
  • Expert clinical experienceIt integrates the clinical experience of more than 300 well-known pediatric experts from Beijing Children's Hospital.
  • High-quality medical record dataIt uses high-quality medical records from experts that have been anonymized over decades.
• Model training methodsThe training of the "Futang Baichuan" pediatric large model employed the following methods:
  • Training with massive amounts of professional medical dataIt has built a professional medical database with trillions of tokens.
  • Clinical experience integrationCombining expert clinical experience with model training.
  • Multi-dimensional technology enhancementThe model is enhanced in five aspects: evidence-based, reasoning, memory, dialogue, and multimodal.
  • Self-built evidence-based medicine knowledge baseIt includes over 40,000 Chinese and English guidelines and expert consensus statements, over 38 million research papers, and 170,000 drug instructions.

Specific applications of Futang Baichuan

• AI Pediatrician (Grassroots Version):
  • Designed for routine pediatric disease diagnosis and treatment scenarios.
  • Taking the diagnosis of viral encephalitis in children as an example, AI pediatricians can form a preliminary diagnosis and provide examination suggestions.
  • Our outpatient diagnostic capabilities have reached the level of attending physicians at Beijing Children's Hospital.
  • Pilot applications will be launched in national regional medical centers, pediatric medical consortia, county-level tertiary hospitals, and community hospitals.
• AI Pediatrician Expert Edition:
  • Focusing on the diagnosis and treatment of rare and complex pediatric diseases.
  • She started working at Beijing Children's Hospital in February 2025.
  • He participated in more than 10 multidisciplinary consultations for difficult and rare diseases and pediatric ward rounds.
  • The treatment plan was consistent with the consultation results of experts at Beijing Children's Hospital in 95% of cases.

Application scenarios of Futang Baichuan

• Online consultationPatients can consult with AI pediatricians through an online platform to obtain preliminary diagnoses and advice.
• Remote consultationIt supports remote multidisciplinary consultations, allowing experts to make diagnostic and treatment decisions with the assistance of AI.
• Medical education and trainingProvides training and educational support for primary care physicians and medical students. Through simulated case studies, it helps primary care physicians and medical students develop clinical reasoning skills. It also provides the latest pediatric medical knowledge and guidelines to help physicians and medical students update their knowledge base in a timely manner.
• Public Health and Disease PreventionSupport public health departments in disease surveillance and prevention. Through big data analysis, monitor the prevalence trends of pediatric diseases and provide prevention recommendations and health guidance for common childhood illnesses.
• Scientific Research and Data AnalysisSupport research in the field of pediatrics by providing data support and analytical tools. Analyze large amounts of pediatric case data to uncover potential disease patterns and treatment effects. Provide data support to researchers to assist in the implementation of research projects.
