Microsoft Claims Medical Leap, Grammarly Buys Superhuman

Microsoft unveiled an AI “diagnostic orchestrator” that solved more than eight out of ten challenging New England Journal of Medicine cases, eclipsing physicians who managed two out of ten. The company calls the achievement a “path to medical superintelligence.”

The system pairs OpenAI’s o3 model with an agent that orders tests and synthesizes results, mimicking a panel of multidisciplinary experts. Microsoft says it is cheaper than human doctors because it chooses diagnostic tests more efficiently.

By surpassing specialists on difficult cases, the research marks a step-change in AI’s demonstrated medical reasoning. Microsoft stresses the tool will complement clinicians and concedes it is not yet ready for clinical use.

Chinese AI companies are loosening the U.S.’s grip on the technology, challenging American superiority. Users across Europe, the Middle East, Africa, and Asia are adopting large language models from DeepSeek and Alibaba instead of ChatGPT.

Customers range from multinational banks to public universities, showing mainstream acceptance of the Chinese alternatives. The shift sets China and the U.S. on a collision course for AI leadership.

The report frames the trend as the start of a global AI arms race rather than a U.S.-dominated marketplace. American superiority is being tested in real time by rising Chinese contenders.

Grammarly has acquired AI email client Superhuman as it expands its productivity suite. Neither side disclosed financial terms.

Superhuman raised more than $114 million and was last valued at $825 million. CEO Rahul Vohra and his team will move to Grammarly, which plans to build AI agents for inbox workflows using Superhuman’s technology.

The deal follows Grammarly’s 2024 purchase of Coda and its May 2025 $1 billion non-dilutive funding from General Catalyst. Grammarly states that adding Superhuman embeds its AI agents in the communication channel where professionals spend substantial portions of their day.

A military research institute in China unveiled a mosquito-sized UAV for covert operations. The tiny drone from the National University of Defence Technology has hair-thin legs, two wings, and can be controlled via smartphone.

Researchers say the micro UAV’s onboard sensors make it fit for reconnaissance and special missions on the battlefield. The device was shown on state-run military channel CCTV 7 by student Liang Hexiang.

The project joins Harvard’s RoboBee and the US military’s pocket-sized Black Hornet in advancing insect-scale surveillance platforms. DARPA’s work on cyborg insects shows multiple governments already have micro robotic or hybrid systems for real-world reconnaissance.

Mayfield managing director Navin Chaddha has carved out $100 million from the firm’s latest funds to back “AI teammate” startups targeting people-heavy professional services. He recently led Gruve’s Series A, positioning the security consulting newcomer as a proof point for AI-driven service margins.

Chaddha frames law, consulting, and accounting as a $5 trillion market where AI can automate 80% of tasks and deliver 60–70% blended margins through outcome-based pricing. Gruve bought a $5 million-revenue security consultancy and lifted it to $15 million in six months while holding gross margin near 80%.

He says giants like McKinsey, Accenture, and Infosys are locked into hourly billing and will struggle to pivot, opening space to serve 30 million U.S. small businesses they ignore. Chaddha contends those down-market startups can avoid direct fights now yet still challenge the incumbents within a decade.
