The U.S. Department of Defense has reached a notable milestone in its artificial intelligence push: 1.5 million people are now using GenAI.mil, the Pentagon's in-house generative AI platform, according to DefenseScoop.

The figure comes from the Pentagon's Chief Technology Officer, Emil Michael, who highlighted the platform's adoption as a sign of growing AI integration across the department. GenAI.mil is designed to cut down on routine, time-consuming tasks — what officials describe as "drudge work" — for the department's employees.

The scale is significant. With 1.5 million users, the platform has moved well beyond a pilot program into something that touches a substantial share of the department's civilian and military workforce on a day-to-day basis.

The milestone matters because it signals that AI adoption inside the U.S. military is no longer theoretical — it's operational, at scale, and being used to change how the world's largest defense organization handles routine work.
