According to Satya Nadella, SDBench introduces a groundbreaking benchmark that converts 304 New England Journal of Medicine (NEJM) cases into interactive diagnostic simulations for healthcare AI. This development enables AI systems to engage in realistic clinical workflows, such as asking targeted questions, ordering diagnostic tests, and assessing cost-effectiveness, closely mirroring the complexity of real-world medical decision-making (Source: Satya Nadella on Twitter, June 30, 2025). The SDBench benchmark is expected to accelerate the practical deployment of AI in healthcare by providing a rigorous, scenario-based evaluation framework for diagnostic models, which could enhance patient outcomes and operational efficiency across hospitals and clinics.
