The Department of War deployed GenAI.mil, a secure enterprise-wide generative AI platform, to roughly 3 million military personnel, civilian employees, and contractors on December 9, 2025. The platform launched with Google's Gemini for Government and expanded over the following months to include xAI's Grok and OpenAI's ChatGPT, supporting day-to-day work tasks such as drafting documents, summarizing reports, and conducting research.

Details

GenAI.mil launched on December 9, 2025, with Google's Gemini for Government as its first model, and is managed by the Chief Digital and Artificial Intelligence Office (CDAO). It is authorized to handle Controlled Unclassified Information (CUI) at Impact Level 5 (IL5), meaning it can be used for sensitive but unclassified official work. The platform supports file uploads in multiple formats (PDF, DOCX, PPTX, images), provides Retrieval Augmented Generation (RAG) for document-grounded responses, persistent chat histories, and secure web grounding. By February 2026, five of the six military branches had formally adopted it as their preferred enterprise AI system, with over 1.1 million unique users reported; xAI's Grok and OpenAI's ChatGPT joined the platform in early 2026.

Other practices by U.S. Department of War

OtherThe Department of War integrated OpenAI's AI models into classified military networks under an agreement reached in February 2026, allowing the use of advanced AI for both warfighting and enterprise tasks in secure, cloud-based classified environments. The agreement includes contractual limits prohibiting use for mass domestic surveillance or directing autonomous weapons systems.OtherThe Department of War announced an Artificial Intelligence Acceleration Strategy on January 9, 2026, directing the department to develop AI agents for battle management and decision support, mandate federated data access for AI systems, and require that the latest commercial AI models be made available within 30 days of public release. By April 2026, DoW personnel had used GenAI.mil's Agent Designer tool to build over 100,000 agents for unclassified administrative tasks, while the strategy's Agent Network initiative continues to direct AI agent development for battle management and decision support.Data AnalysisThe Department of War deployed the Maven Smart System (MSS), an AI platform built by Palantir, to analyze data from drones, satellites, radar, and other sensors to identify objects and potential targets and support battlefield decision-making. The program traces its roots to Project Maven, launched in 2017; Palantir became the primary contractor under a May 2024 contract. As of 2026, the Pentagon is expanding MSS department-wide as a formal program of record.
