# Pentagon Launches GenAI.mil Platform for 3 Million Military Personnel

> The Department of Defense has quietly become one of the largest AI deployments on the planet. Its new GenAI.mil portal has already onboarded more than 1.7 million active users, giving uniformed and civilian personnel access to OpenAI's ChatGPT Mil, xAI's Grok for Government, and Google's Gemini for authorized work. Five of the six military branches have adopted it as their default AI platform. The detail that jumps out is who is missing. Anthropic's Claude was excluded after the current administration flagged it as a supply-chain risk, a striking omission given the company's prominence in enterprise and government circles elsewhere. It is a reminder that AI procurement is now as much about politics and trust as about benchmarks. Also telling: personnel have already created more than 100,000 custom agents to automate recurring tasks. That is bottom-up adoption at a scale most enterprises only dream about, happening inside an institution not known for moving fast. Whatever you think about the military using generative AI, this is what real, mandatory-scale rollout looks like.
