MEMORANDUM FOR ALL DEPARTMENT OF WAR PERSONNEL

SUBJECT: Harness Artificial Intelligence Now with GenAl

I am pleased to introduce GenAl.mil, a secure generative artificial intelligence (Al) platform for every member of the Department of War. It is live today and available on the desktops of all military personnel, civilians, and contractors. With this launch we are taking a giant step toward mass Al 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.

The first GenAl platform capability is Google Gemini, a frontier Al application that can help you write documents, ask questions, conduct deep research, format content, and unlock new possibilities across your daily workflows. Gemini is the first of several enterprise Al applications that will be rolled out on the GenAI platform. It is secure, certified up to Impact Level 5 (ILS), and is fully authorized to handle CUI.

Victory belongs to those who embrace real innovation. Rather than being reliant on the dusty, antiquated systems of a bygone era, we are thinking ahead here in the Department of War. GenAl.mil is part of this monumental transformation. It removes wasted time and focuses more of our energy into decisive results for the warfighter.

Access is straightforward. Navigate to GenAl.mil and you will be able to access the tool with your CAC. The platform is certified secure for operational use on NIPR.

I expect every member of the Department to log in, learn it, and incorporate it into your workflows immediately. Al should be in your battle rhythm every single day.

It should be your teammate. By mastering this tool, we will outpace our adversaries. The power is now in your hands.
