JD Health’s Zhiyi sits at the center of a broader AI healthcare architecture that includes the proprietary medical LLM Jingyi Qianxun and patient-facing AI Dawei, plus more than 1,500 specialized AI agents deployed across hospitals and disease areas to support workflows from evidence retrieval to patient follow-up.

The platform draws on specialized, evidence-backed resources such as guidelines from the China Anti-Cancer Association for holistic cancer management, and offers over 200 medical calculators for diagnosis, risk assessment, dosing, and cardiovascular risk, along with tools for literature reviews and patient education.

JD Health has built dedicated evaluation systems, including MedScope to assess evidence quality and usefulness, and MedSafety to flag high‑risk scenarios across 26 categories, ensuring clinical safety and reliability.

Zhiyi enables multimodal inputs, allowing doctors to upload and analyze lab results, prescriptions, images, PDFs, and past consultations to reduce manual data entry and save time.

A core feature is dynamic evidence-location, which traces AI conclusions back to original texts to ensure traceability and explainability for clinicians.

The value of medical AI lies in trusted evidence, safety, workflow integration, and scalable access; Zhiyi exemplifies an end-to-end approach that combines technology, evidence, partnerships, and logistics to empower doctors and improve patient care.

Zhiyi supports complex clinical reasoning with a Deep Thinking mode that breaks down questions, weighs evidence levels, and provides structured references for multi-condition and multi-medication scenarios.

In August, JD Health partnered with PICA Health to integrate Zhiyi into PICA Health’s app, giving about three million registered primary-care doctors free access to Deep Thinking, medical calculators, and research assistance, expanding AI resources to grassroots clinicians.

Zhiyi consolidates over 50 million medical papers, guidelines, and 160,000 pharmaceutical instructions, serving more than one million doctors with over 20 million clinical decision-making interactions.

JD Health’s supply chain infrastructure enables widespread access to medicines and healthcare products, reaching over one million villages and delivering 87.1% of orders same or next day in county-level areas, linking AI-guided clinical decisions with real-world drug accessibility.

Zhiyi, launched in January 2026, is an evidence-based AI assistant for healthcare professionals in China designed to integrate into doctors’ daily work and decision-making.
