JD Health’s Zhiyi sits within a broader AI healthcare architecture that leverages the Jingyi Qianxun medical LLM and connects to tools like Dawei (AI doctor) and a network of more than 1,500 specialized AI agents across hospitals and disease areas.

To ensure clinical safety and reliability, JD Health has established evaluation systems such as MedScope for evidence quality, accuracy, and usefulness, and MedSafety to address high-risk medical scenarios across 26 categories.

The design philosophy centers on augmenting doctor judgment rather than replacing it, emphasizing trusted evidence, seamless workflow integration, safety controls, and broad accessibility across care settings.

The platform offers specialized, evidence-backed resources, including guidelines from the China Anti-Cancer Association and more than 200 medical calculators for diagnosis, risk assessment, dosing, and cardiovascular risk, plus research-assistance tools for literature reviews and patient education.

Zhiyi supports multimodal inputs, enabling doctors to upload and analyze lab results, prescriptions, images, PDFs, and prior consultations to reduce manual data entry and review time.

A Deep Thinking mode breaks down complex questions, assesses evidence levels, and provides structured references, with examples drawn from oncology guidelines and access to numerous medical calculators to support clinical reasoning.

Traceability is central, showing the original texts and sources behind AI conclusions to help doctors verify evidence, with dynamic location of evidence pointing back to primary sources.

Ultimately, the value of medical AI lies in trusted evidence, safety, workflow integration, and scalable access, demonstrated by Zhiyi’s end-to-end approach that combines technology, partnerships, and logistics to empower clinicians and improve patient care.

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

In August, JD Health partnered with PICA Health to integrate Zhiyi into PICA Health’s app, offering free access to Deep Thinking, medical calculators, and research assistance to about three million registered primary-care doctors in China.

JD Health’s supply chain network supports widespread access to medicines and healthcare products—reaching over one million villages with high last-mile delivery coverage—linking AI-informed decisions to real-world drug availability.

Zhiyi is an evidence-based AI assistant launched in January 2026 to support clinical decision-making, medical research, and patient management for healthcare professionals in China.
