We believe the people responsible for defending the country should have access to the best tools available, and it is important for the United States and other democratic countries to understand how, with the proper safeguards, AI can help protect people, deter adversaries, and prevent future conflict. That’s why we’re bringing ChatGPT to GenAI.mil—to empower American service members with AI capabilities built to the highest standards, delivering reliable performance and mission advantage. Our goal is to help governments use AI effectively and safely. We believe we can best achieve that by participating in efforts like GenAI.mil⁠(opens in a new window), where we help shape the technical norms for how AI is deployed across government.

OpenAI will deploy a custom version of ChatGPT on GenAI.mil, approved for the Department’s unclassified work. The system runs in authorized government cloud infrastructure with built-in safety controls and protections for the Department’s highly sensitive data, giving teams secure access to generative AI.

ChatGPT is designed to support day‑to‑day tasks that strengthen readiness and mission execution for American service members, including:

This effort reflects how we approach government work more broadly: focused, practical, safety-forward, and grounded in real-world use.
