Shanghai releases the first AI diagnostic and treatment evaluation benchmark for difficult medical cases.

On July 18, 2026, the Medical Sub-forum of the World Artificial Intelligence Conference was held at Xuhui West Bank in Shanghai. During the forum, Shanghai released the industry's first AI diagnostic benchmark for difficult cases, covering 30 clinical specialties, specifically designed to test the real capability of medical large models in handling complex cases. At the same time, the existing medical AI evaluation system was updated to version 5.0, adding the "atomic skill" evaluation method, which can correct false information generated by AI models. In terms of infrastructure, the Shanghai Health Industry AI Computing Power Service Center was officially unveiled, connecting the entire chain from computing power supply, data synthesis, model training, to intelligent applications. It is expected that by the end of 2026, the scale of Shanghai's medical and health corpus will exceed 2PB, and the data preparation cycle can be shortened by more than 60%. The forum also released the "2026 Artificial Intelligence + Health Shanghai Practice" case collection, summarizing the application experience of AI in seven major scenarios including clinical decision support, patient treatment, traditional Chinese medicine intelligence, grassroots public health, hospital management, among others. Currently, Shanghai has been approved as a national pilot base for AI applications in the medical field, covering all seven major medical application scenarios.
