Today, OpenAI for Government is announcing the next phase of our national security work: bringing ChatGPT to GenAI.mil, the Department of War's secure enterprise AI platform used by 3 million civilian and military personnel.

We believe the people responsible for defending the country should have access to the best tools available. That's why we're bringing ChatGPT to GenAI.mil—to empower American service members with AI capabilities built to the highest standards.

Deploying a custom ChatGPT product on GenAI.mil

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.

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

- Summarizing and analyzing policy and guidance documents
- Drafting and reviewing procurement and contracting materials
- Generating internal reports and compliance checklists
- Supporting research, planning, mission support, and administrative workflows
