Grok and ChatGPT Join Gemini in Pentagon's Enterprise genAI Portal

The Pentagon’s GenAI.mil portal expanded beyond Google Gemini to include approved versions of ChatGPT and Grok for sensitive, unclassified work across the Defense Department. The rollout gives millions of military, civilian, and contractor users access to multiple commercial AI tools in one secure system. The move reflects the department’s push to speed adoption of generative AI for everyday tasks and agent-building. It also shows continued dependence on a small set of major vendors for defense AI infrastructure.
