Pentagon brings on Grok and ChatGPT for military use
The additions give military and civilian users access to multiple frontier models for document-heavy unclassified work, and GenAI.mil has drawn 1.7 million users.
On Monday, the Department of Defense launched OpenAI's ChatGPT Mil and Starshield AI's Grok for Government on the GenAI.mil platform, enabling personnel to handle sensitive, unclassified information securely.
The Pentagon launched the GenAI.mil platform nine months ago to provide more than 3 million personnel with access to commercial AI models, enhancing productivity while ensuring data security.
ChatGPT Mil offers familiar commercial features, while Starshield AI's Grok for Government provides "advanced capabilities, including deep-thinking inference," according to the DoD; both tools are accredited for Controlled Unclassified Information at Impact Level 5 .
Integrating multiple models helps the DoD avoid vendor lock-in and promotes a broader American AI ecosystem; this expansion follows a legal dispute where the Pentagon designated Anthropic a "supply-chain risk," excluding the company's Claude model.
Pentagon officials plan to continuously expand AI capabilities, with OpenAI's GPT-5.6 Terra expected to join the platform soon; the department intends to utilize these tools for planning, logistics, and policy tasks, emphasizing meaningful human judgment.
