Microsoft's MAI-DxO, a multi-agent diagnostic orchestrator, was correct on 83% of complex New England Journal of Medicine cases in simulation, versus 36% for generalist physicians, according to a study in Science. The data suggests most of the gain comes from stronger base models, with orchestration adding a smaller lift, mainly on complex cases.

Microsoft AI CEO Mustafa Suleyman says the company is prioritizing token efficiency and compact, single-purpose models over general-purpose frontier systems. New models MAI-Cyber-1-Flash and MAI-Image-2.5-Flash claim strong cost-performance gains, but rely on an orchestration layer that still routes hard tasks to OpenAI's reasoning models.

Microsoft has launched MAI-Cyber-1-Flash, its first cybersecurity-specialized model, alongside Perception, an agentic platform for automated threat detection and remediation. The company claims the model outperforms rivals from Anthropic, Google and OpenAI on the Cyber Gym benchmark, though no independent scores have been published.
