The Pentagon now offers bespoke AI chatbots to its staff.
Custom ChatGPT and Grok versions are on its secure portal.
Over 1.7 million of its 3 million personnel already use it.
What happened
The Pentagon has launched custom versions of OpenAI's ChatGPT and xAI's Grok, called ChatGPT Mil and Grok for Government, through its GenAI.mil secure portal for its 3 million personnel.
Why it matters
The tools are tailored to "warfighter needs" and aim to give the Department of Defense an edge without sacrificing security. The launch notably excludes Anthropic's Claude, which was labeled a supply-chain risk after a dispute over safety guardrails.
What to watch
GenAI.mil has already onboarded more than 1.7 million unique users. Grok is positioned for broader militaristic uses, including faster mission execution, while ChatGPT Mil will focus on routine unclassified work like logistics and planning.

The Pentagon's launch of custom ChatGPT and Grok versions marks a major step in its broader push to weave AI into daily operations. The portal is designed to let personnel use commercial frontier models without routing sensitive government data through consumer channels, and the official military version is exempt from the data collection typical of consumer products.
A notable element is the absence of Anthropic's Claude. The Trump administration labeled the company a supply-chain risk after it refused the Pentagon unrestricted use of its tools, a designation Anthropic is fighting in court. This move highlights the Pentagon's effort to work with other companies following that dispute, while also partnering with firms like Amazon Web Services, Microsoft, Nvidia, and Reflection AI to bolster its AI capabilities.
The department positions each tool differently. ChatGPT Mil offers a familiar experience for routine, unclassified work, while Grok for Government is framed in more militaristic terms, promising immediate productivity gains and faster, more precise mission execution. The portal's rapid adoption, with over 1.7 million unique users already onboarded, suggests strong demand from personnel.
