The War Department increased its artificial intelligence offerings by launching versions of Grok and ChatGPT to GenAI.mil yesterday, to go alongside Google's Gemini.
The GenAi.mil website premiered in December 2025 with an email to War Department employees inviting them to try the department's special version of Gemini, which is cleared for Impact Level 5 use, including controlled unclassified information.
"I am pleased to introduce GenAI.mil, a secure generative [artificial intelligence] platform for every member of the Department of War," Secretary of War Pete Hegseth wrote in his message to the workforce. "With this launch, we are taking a giant step toward mass AI adoption across the department. This tool marks the beginning of a new era, where every member of our workforce can be more efficient and impactful."
At the time, GenAI.mil hosted a link to the War Department's version of Gemini. Now Starshield AI's Grok for Government and Open AI's ChatGPT Mil are also available, allowing would-be users the opportunity to get a first, second and third opinion.
According to a series of War Department releases yesterday, Grok for Government provides warfighters and department civilians with immediate productivity gains.
"Department personnel will gain access to advanced capabilities, including deep-thinking inference, adaptive reasoning modes (auto, fast and expert), customizable workspaces, persistent projects and reusable playbooks that capture and scale institutional knowledge," the release reads.
The well-known ChatGPT brings familiarity to the department's secure AI environment and is tailored to warfighters and department personnel needs.
"The core experience centers on chat, files, projects and custom [generative pretrained transformers], with additional features sequenced over time," the department's release states. "ChatGPT Mil supports document-heavy unclassified work across the department, including planning, policy, logistics and administration, and is built for scale to support more than three million department personnel."
In his original letter to the force introducing GenAI.mil, Hegseth said he expects AI tools to make the department work faster and more efficient.
"I expect every member of the department to log in, learn it and incorporate it into your workflows immediately," he stated. "AI should be in your battle rhythm every single day; it should be your teammate. By mastering this tool, we will outpace our adversaries."
Live and on-demand training for each platform are available at no cost to department employees.
