The U.S. government has moved forward with integrating Elon Musk’s Grok artificial intelligence systems into federal operations following multiple agreements in 2025 and early 2026, including a reported $200 million contract signed by the Pentagon under its “Grok for Government” program that gives federal agencies access to advanced Grok models such as Grok 4 for mission planning and internal use. The Department of War, rebranding aspects of the Defense Department’s AI efforts, announced in December 2025 that it would embed xAI’s frontier AI capabilities into its GenAI.mil platform, allowing secure AI tools for millions of military and civilian personnel starting in early 2026, and the General Services Administration earlier in September 2025 had facilitated a unique OneGov agreement making Grok models broadly available to federal agencies at low cost to accelerate adoption. The integration follows xAI’s broader federal partnerships and positions the Grok family of models across government workstreams alongside other AI providers as part of a strategic push to modernize U.S. AI infrastructure.
