Bianshi TCM Four Diagnosis Robot

Developed by AthenaEyes, the Bianshi TCM Four Diagnosis Robot represents a technological bridge between traditional Chinese medicine diagnostic practices and modern artificial intelligence. The system automates the classical “four examinations” (四诊) method—inspection (望), auscultation and olfaction (闻), inquiry (问), and pulse-taking (切)—delivering full health assessments in approximately five minutes.

Product Overview

The Bianshi system addresses a persistent challenge in Chinese healthcare: the shortage of experienced TCM practitioners, particularly in primary care settings. By encoding diagnostic expertise into AI algorithms, the device enables healthcare facilities without TCM specialists to offer constitution-based health assessments and wellness guidance.

Named after Bianshi (砭石), the ancient healing stones used in early Chinese medicine, the product draws on AthenaEyes’ proprietary large language model of the same name. This multimodal foundation model, released in May 2023, integrates visual analysis, signal processing, and natural language understanding to replicate the holistic diagnostic approach characteristic of TCM practice.

Key Features

Bianshi TCM Four Diagnosis Robot is an AI-powered diagnostic system by AthenaEyes, automating tongue imaging, facial analysis, pulse measurement, and voice-guided inquiry to deliver a five-minute constitution assessment.

• Automated Tongue Diagnosis: High-resolution imaging captures tongue appearance, with AI algorithms analyzing tongue shape, color, coating, and texture to identify patterns associated with specific health conditions and constitution types.

• Facial Analysis: Computer vision technology examines facial complexion, features, and color distribution to detect signs traditionally associated with organ system imbalances in TCM theory.

• Pulse Diagnosis Module: Sensors measure pulse waveform characteristics at multiple points, digitizing the subtle variations that TCM practitioners interpret through fingertip palpation.

• AI-Guided Inquiry: Voice-interactive questioning collects symptom and lifestyle information, with the system adapting its queries based on preliminary findings from physical examinations.

• Constitution Classification: Analysis outputs include classification into the nine standard constitution types recognized in TCM, with associated risk factors and health tendencies.

• Report Generation: Assessment reports provide health scores, constitution analysis, risk alerts, and personalized recommendations for diet, lifestyle, and preventive measures.

Technical Specifications

Bianshi processes tongue, facial, pulse, and inquiry inputs through a multimodal medical LLM in approximately 5 minutes, classifying patients into 9 standard TCM constitution types with digital health reports.

Clinical Applications

The Bianshi system serves as a screening and health management tool rather than a clinical diagnostic device. Primary application scenarios include:

Community Health Services: Enables community health centers and village clinics to provide TCM-style health assessments without specialist staffing, supporting China’s tiered healthcare system and primary care strengthening initiatives.

Pharmacy Health Stations: Retail pharmacies deploy the system as a value-added service, generating health reports that can guide over-the-counter product recommendations and customer engagement.

Corporate Wellness Programs: Employer-sponsored health screenings use the device for rapid constitution assessment and personalized wellness guidance.

Health Management Centers: Preventive care facilities incorporate TCM-based assessments alongside conventional health examinations for holistic evaluation approaches.

Technology Foundation

The Bianshi large language model underlying this product was developed with substantial computational resources. AthenaEyes reports training capacity of 400P (petaflops), with plans to expand to a dedicated 1000P medical AI computing center. The model supports multimodal inputs including consultation text, medical imaging, and audio data.

The system incorporates privacy-preserving computation techniques to protect patient health information while enabling cloud-based processing and model updates.

Deployment Status

As of 2025, the Bianshi Four Diagnosis Robot has been deployed in Hunan Province, Chongqing, and additional Chinese provinces. The product was showcased at the 2025 World Artificial Intelligence Conference (WAIC) in Shanghai, demonstrating AthenaEyes’ ambitions to position TCM digitalization as a frontier AI application.

The company targets rapid expansion into grassroots healthcare facilities, supporting national policies to strengthen primary care and address regional healthcare disparities.

Frequently Asked Questions

How accurate is the Bianshi diagnosis compared to human TCM practitioners?

According to AthenaEyes, the system’s diagnostic performance is comparable to a TCM practitioner with 8-10 years of clinical experience. However, the device is positioned as a health screening and assessment tool rather than a replacement for clinical diagnosis by licensed physicians.

Does the Bianshi system require TCM training to operate?

The system is designed for use by non-specialist staff. Patients can complete examinations with minimal guidance, and the AI handles interpretation and report generation automatically. Healthcare facilities without dedicated TCM practitioners can offer constitution-based health services through the device.

What conditions can the Bianshi system detect?

The system performs constitution classification and health risk screening rather than disease diagnosis. It identifies patterns associated with conditions such as metabolic imbalances, digestive issues, fatigue syndromes, and stress-related symptoms, providing recommendations for prevention and lifestyle adjustment.
