  • The integration is targeted for initial deployment in early 2026 and will allow all military and civilian personnel to use xAI's capabilities.
  • The department added that users will also have access to “real‑time global insights from the X platform.”
  • The announcement comes on the heels of xAI announcing xAI For Government in July.

The U.S. Department of War on Monday announced a new agreement with Elon Musk’s AI startup xAI for the deployment of the latter’s capabilities on the department’s AI platform.

GenAI.mil is the War Department's AI platform. Under the deal, xAI's frontier AI systems, based on the Grok family of models, will be embedded directly into GenAI.mil. The integration is targeted for initial deployment in early 2026 and will allow all military and civilian personnel to use xAI's capabilities at “Impact Level 5 (IL5), enabling the secure handling of Controlled Unclassified Information (CUI) in daily workflows,” the department said.

Impact Level 5 (IL5) is a US Department of Defense (DoD) cloud security classification for handling highly sensitive Controlled Unclassified Information (CUI) and National Security Systems (NSS) data. The department added that users will also have access to “real‑time global insights from the X platform.”

xAI For Government

The announcement comes on the heels of xAI announcing xAI For Government in July. xAI For Government is a suite of AI products available to U.S. government customers, including federal, local, state, and national security customers.

xAI also inked a $200 million contract with the U.S. Department of Defense, now the Department of War, in July. Similar awards were also handed to OpenAI, Alphabet’ Google and Anthropic and were aimed at scaling the adoption of advanced AI capabilities in the department.

The partnerships will enable the Department to leverage the technology and talent of U.S. frontier AI companies to develop agentic AI workflows across a variety of mission areas, the Department then said.
