"Red House·Qiyuan" AI Obstetrics and Gynecology Vertical Large Model Released

Background

On March 6, 2026, the Obstetrics and Gynecology Hospital of Fudan University released the "Red House·Qiyuan" AI Obstetrics and Gynecology Vertical Large Model at its Qingpu branch. The model was developed jointly by the hospital and Alibaba Cloud.

The release event included a demonstration in which the AI system engaged in a comparative performance with clinicians across pre-diagnosis, diagnosis, and post-diagnosis stages of care. The timing preceded International Women's Day. Representatives from Shanghai health authorities, Fudan University, and artificial intelligence industry associations attended.

What was achieved

The model utilizes a three-layer architecture comprising a domestic foundational base built on heterogeneous computing power and the Tongyi Qianwen model, a specialist alignment layer, and scenario-specific intelligent agents. It realizes three breakthroughs by reconstructing knowledge expression methods, clinical reasoning mechanisms, and the embedding of processes into clinical workflows. This approach addresses challenges of fragmented AI applications, inconsistent data, and insufficient specialization in obstetrics and gynecology.

The "Little Red" AI patient assistant developed on this model completed filing procedures as Shanghai's first generative AI application in the medical services field under relevant regulations. The hospital also established the "Red House Digital Intelligence Innovation Alliance," entering agreements with 19 medical institutions from the pan-Yangtze River Delta region and nine enterprises to advance collaborative digital innovation in the specialty.

How it works

The vertical large model draws on a large volume of obstetrics and gynecology-specific data, including millions of clinical cases, more than one thousand guidelines and consensus statements, and internal teaching and specialist materials. These are processed by structuring core diagnostic and treatment pathways, integrating fragmented data, constructing a specialty knowledge graph, and creating unified semantic mapping rules. This enables the incorporation of experienced physicians' clinical thinking patterns to support standardized, evidence-based outputs and minimize issues such as inaccuracies that can occur with general models.

In demonstrated use, the "Little Red" assistant interprets patient reports, for example advising on an HPV-positive result by recommending further liquid-based cytology testing and providing guidance. A multimodal diagnostic agent can analyze colposcopy images in seconds to identify and annotate lesions and suggest management pathways. The system supports full-process management from before to after clinical encounters, including automated reminders sent to patients six months later with pre-consultation questionnaire links. It incorporates emotional perception capabilities during patient interactions.

What it means for international patients

The Obstetrics and Gynecology Hospital of Fudan University operates an international medical department serving foreign patients at its Huangpu and Yangpu campuses in Shanghai. English-language interpretation support can be arranged through this department.

The new AI model and "Little Red" assistant are intended to enhance full-process management and support in obstetrics and gynecology care. International patients should contact the hospital directly to confirm availability, eligibility, and any application of these tools to their care. Inquiries can be directed to the international medical services contact points provided on the hospital's official website.

About the hospital

The Obstetrics and Gynecology Hospital of Fudan University, popularly known as Red House Hospital because of its historic red-brick buildings, is located in Shanghai. It is a tertiary grade A specialized hospital affiliated with Fudan University's Shanghai Medical College, integrating clinical services, teaching, and research. It traces its origins to 1884 as one of the earliest dedicated women's hospitals in Shanghai.

The hospital maintains comprehensive subspecialties in obstetrics and gynecology, including gynecologic oncology, reproductive endocrinology and infertility, high-risk pregnancy management, and fetal medicine. It has an established international medical department to accommodate patients from abroad.
