The U.S. Department of War is rapidly expanding AI capabilities, with strong adoption of its GenAI.mil platform. A LinkedIn post from the Office of the Under Secretary for Research and Engineering reports 1.3 million users and more than 57 million prompts processed.
Launched last year, GenAI.mil provides conversational chat, file uploads, and retrieval-augmented generation from user-supplied documents. It also offers secure web grounding, deep research functions, and persistent chat histories.

Google’s Gemini models were the first to be deployed within the new platform. The Pentagon has also outlined plans to incorporate ChatGPT from OpenAI and Grok, developed by xAI.

Officials said over 6.9 million documents have been uploaded to the system, alongside more than 870,000 AI agent sessions.
The initiative is aimed at reducing time spent on repetitive and administrative tasks, enabling warfighters to focus on mission-critical decision-making.

Leaders emphasized that the deployment of generative AI is already improving operational readiness and accelerating response times. By integrating AI tools directly into workflows, the department is seeking to enhance both speed and precision in complex environments.
