Musk’s AI tool Grok will be integrated into Pentagon networks, Sec Hegseth says

Defense Secretary Pete Hegseth announced that the US military will begin integrating Elon Musk’s artificial intelligence tool, Grok, into Pentagon networks. The defense secretary said that the integration of Grok into military systems would go live later in January. “Very soon we will have the world’s leading AI models on every unclassified and classified network throughout our department,” Sec Hegseth said. Sec Hegseth also unveiled a new “AI acceleration strategy” at the Department of Defense that he said will “unleash experimentation, eliminate bureaucratic barriers, focus on investments, and demonstrate the execution approach needed to ensure we lead in military AI and that it grows more dominant into the future”. In December 2025, it was announced that the defense department had selected Google’s Gemini, another AI model, to power the military’s new internal AI platform, known as GenAI.mil. Sec Hegseth also said that at his direction, the DOD’s Chief Digital and Artificial Intelligence Office “will exercise its full authority to enforce” the department’s “data decrees and make all appropriate data available across federated IT systems for AI exploitation, including mission systems across every service and component”.
