The U.S. Department of Defense has added ChatGPT Mil, a dedicated OpenAI deployment, and xAI's Grok for Government to its GenAI.mil enterprise portal alongside Google Gemini. The platform is intended to provide more than 3 million military personnel, civilian employees, and contractors with approved generative-AI tools for unclassified and controlled-unclassified-information work, including planning, policy, logistics, administration, and document processing. ChatGPT Mil operates separately from OpenAI's commercial service; DISA is building its environment and the NSA is assessing intrusion and containment risks.
ChatGPT Mil and Grok for Government reportedly received Impact Level 5 authorization, allowing their environments to store and process sensitive, non-public unclassified data. Pentagon and OpenAI officials said the GenAI.mil deployments are not intended for combat use because of operational and connectivity constraints, while the department continues evaluating AI for operational applications. The multi-vendor strategy is designed to provide distinct frontier-model capabilities without vendor lock-in; Anthropic's Claude was not included following a dispute over restrictions on mass surveillance and lethal autonomous weapons.

The Department of Defense added OpenAI's ChatGPT Mil and Starshield AI's Grok for Government to GenAI.mil alongside Google Gemini. The models received Impact Level 5 authorization for handling sensitive, non-public unclassified data and are intended for document-heavy unclassified work rather than combat use.
The Department of Defense announced plans to make its GenAI.mil platform available to more than 3 million military personnel, civilian employees, and contractors.
Anthropic sued the U.S. government over the supply-chain-risk designation and removal order. A federal district judge later ruled that the Pentagon's actions against Anthropic were illegal and baseless.
The department designated Anthropic a supply-chain risk and ordered personnel to remove Anthropic AI products from national-security systems and assets following a dispute over contractual use restrictions.
The Department of Defense began work on a ChatGPT version capable of processing controlled unclassified information in a separate, secured environment from OpenAI's commercial service.
The Pentagon launched the GenAI.mil generative-AI portal with Google Gemini as its initial tool for DoD personnel.

The Pentagon is rapidly expanding its use of generative AI across the Department of Defense, with officials saying adoption of the `GenAI.mil` platform has surged from about 80,000 users in late 2025 to roughly 1.5 million by June 2026, out of a workforce of around 3.5 million. Defense officials said the platform is already being used for administrative work including evaluation reports, medal citations, counseling statements, and reports mandated by Congress, while the department has also signed agreements with major AI vendors to deploy tools on classified networks for lawful operational use. OpenAI said `ChatGPT` will be added to `GenAI.mil` in early July for more than 3 million civilian and military personnel, with certifications for controlled unclassified information and `Impact Level 5`. The expansion has drawn scrutiny because AI-generated submissions to Congress could contain errors or mischaracterizations that weaken oversight of military spending, particularly as the Defense Department seeks a record **$1.5 trillion** budget for fiscal year 2027; officials also noted that more than 100,000 AI agents have already been built on the platform as demand grows for higher token capacity and more efficient model use.

The Pentagon added xAI’s **Grok** to a Defense Department review process late, according to reporting on the government’s evaluation of artificial intelligence tools for defense use. The move placed Elon Musk’s company into a sensitive federal procurement and assessment track alongside other AI providers as the department examined how large language models could support military and national security functions. Publicly available supporting material also points to related technical tracking activity, including a Chromium issue entry identified as `474817168`, though no public synopsis was provided in the referenced record. Together, the references indicate that Grok became part of a broader U.S. defense AI evaluation effort, highlighting both the policy significance of vendor selection and the technical scrutiny surrounding tools considered for government deployment.

The US Department of Defense has officially launched GenAI.mil, a generative artificial intelligence platform designed for military use and powered by Google’s Gemini AI application. Secretary of Defense Pete Hegseth issued a memorandum instructing all military personnel, civilians, and contractors to immediately incorporate the platform into their daily workflows, emphasizing its role in maintaining a technological edge over adversaries. GenAI.mil is authorized to handle controlled unclassified information and is accessible from all Pentagon and global military base desktops, with plans to expand its capabilities by integrating additional advanced AI models in the future. The platform offers features such as natural language conversation, retrieval-augmented generation (RAG), and secure web access, while meeting stringent security requirements including CUI and IL5 certifications for operational environments. The Department of Defense is also rolling out free AI training programs for all staff to maximize adoption and operational effectiveness. This initiative is part of a broader strategy to transform the DoD into an "AI-first" organization, aligning with recent White House directives to secure US leadership in AI-driven defense capabilities.
