The Pentagon now has its own version of ChatGPT and Grok

The Pentagon added custom versions of OpenAI’s ChatGPT and xAI’s Grok to its GenAI.mil portal, giving up to 3 million civilian and military users secure, data‑protected access to frontier models. The rollout replaces earlier Google Gemini access and reflects a binding government decision that reshapes developer‑level AI availability in the defense sector.
