Pentagon launches ChatGPT Mil on GenAI.mil for controlled unclassified information work
The Department of Defense launched OpenAI's ChatGPT Mil on the GenAI.mil platform on August 31, 2026, making the chatbot available for work involving controlled unclassified information (CUI). The system is accredited at Impact Level 5, a DoD cloud-security standard for sensitive unclassified data. ChatGPT Mil joins Google Gemini on the platform, with officials noting Gemini is better for search while ChatGPT excels at text-based tasks. The Pentagon also launched Starshield AI's Grok for Government on the same day to eliminate vendor lock-in. GenAI.mil has attracted over 1.7 million unique users since launching nine months ago and serves the department's more than 3 million personnel.
