The Pentagon now has its own version of ChatGPT and Grok

The Pentagon is adding versions of OpenAI’s ChatGPT and xAI’s Grok to its central portal for AI tools, joining Google’s Gemini. The move gives defense personnel access to multiple leading AI assistants through an official platform.

The rollout shows the Pentagon is moving from AI experimentation toward broader operational access to commercial chatbot tools. It also highlights a growing trend in government procurement: offering competing frontier models side by side rather than relying on a single vendor.
