The US Defense Department has confirmed that Elon Musk’s AI chatbot Grok will begin operating inside the Pentagon network later this month, joining Google’s generative AI tools as part of a major military technology shift. Defense Secretary Pete Hegseth said the Pentagon plans to feed large volumes of military and intelligence data into AI systems to speed up analysis, decision-making, and battlefield readiness. The move signals a far more aggressive approach to artificial intelligence than previous administrations.
