US Deploys ChatGPT Mil and Grok on GenAI.mil

The US Department of War has launched OpenAI's ChatGPT Mil and Starshield AI's Grok for Government on GenAI.mil, significantly expanding the suite of artificial intelligence tools available across its secure enterprise environment.

This move marks the operational rollout of major enterprise capabilities tailored for defense personnel. Both systems have been accredited for Controlled Unclassified Information at Impact Level 5, ensuring compliance with strict security baselines while operating at an enterprise scale.

The release of ChatGPT Mil represents the formal adoption phase of an enterprise partnership established between the Department and OpenAI in 2025. The platform supports document-intensive unclassified workloads across planning, policy, logistics, and administration for over three million personnel across the Joint Force.

ChatGPT Mil brings a familiar commercial experience into the Department's secure environment, tailored to warfighter needs. The core experience centers on chat, files, projects, and custom GPTs, with additional features sequenced over time. The platform supports document-heavy unclassified work across the Department, including planning, policy, logistics, and administration, and is built for scale to support more than 3 million Department personnel.

The Department's integration of Starshield AI's Grok expands operational capabilities, including adaptive reasoning modes, deep-thinking inference, persistent projects, and standardized playbooks designed to preserve institutional knowledge. Starshield AI's Grok for Government will provide the warfighter with immediate productivity gains, stronger knowledge continuity, and more secure and efficient collaboration.

Grok for Government enables the Joint Force to execute missions faster and with greater precision across numerous operational contexts, ranging from market research analysis for acquisition professionals to supply chain management for logisticians. The deployment of Grok for Government represents a milestone in the Department's broader AI Acceleration Strategy.

Since its debut nine months ago, the GenAI.mil ecosystem has onboarded more than 1.7 million unique users. The dual integration broadens access across competing frontier models to reduce vendor lock-in. Through the Chief Digital and AI Office (CDAO) and the Office of the Under Secretary of War for Research and Engineering, the Department will continue scaling frontier AI as a force multiplier across the Joint Force.

This launch is a significant step forward for the US Department of War, as it continues to leverage artificial intelligence to enhance its operational capabilities and support its personnel. The deployment of ChatGPT Mil and Grok for Government demonstrates the Department's commitment to embracing innovative technologies to stay ahead in an increasingly complex and dynamic environment.

The use of AI in the US Department of War is expected to have a significant impact on the future of warfare and defense. As the Department continues to invest in and develop its AI capabilities, it is likely to see significant improvements in its ability to respond to emerging threats and challenges.

The expansion of AI access across the Joint Force is a critical step towards achieving the Department's goals of enhancing its operational capabilities and supporting its personnel. As the US Department of War continues to push the boundaries of what is possible with AI, it is likely to remain at the forefront of innovation and technological advancement in the defense sector.

In the broader context, the deployment of ChatGPT Mil and Grok for Government is part of a larger trend towards the adoption of AI in the defense sector. As AI technology continues to evolve and improve, it is likely to play an increasingly important role in shaping the future of warfare and defense.

The significance of this development cannot be overstated, as it has the potential to revolutionize the way the US Department of War operates and responds to emerging threats and challenges. As the Department continues to invest in and develop its AI capabilities, it is likely to see significant improvements in its ability to support its personnel and enhance its operational capabilities.
