Defense Secretary Pete Hegseth said Monday that Elon Musk’s artificial intelligence chatbot Grok will join Google’s generative AI engine in operating inside the Pentagon network, as part of a broader push to feed as much of the military's data as possible into the developing technology.

Google is expanding the shopping features in its AI chatbot by teaming up with Walmart, Shopify, Wayfair and other big retailers to turn the Gemini app into a virtual merchant as well as an assistant.
