Elon Musk's artificial intelligence startup xAI has officially launched Grok 4, the latest iteration of its AI chatbot, demonstrating rapid advancements in AI technology. Musk announced that Grok will be integrated into Tesla vehicles as early as next week, providing real-time, voice-activated assistance to drivers. In addition to consumer applications, xAI has introduced "Grok for Government," a tailored product suite designed for U.S. federal agencies. This initiative is supported by a $200 million contract awarded by the U.S. Department of Defense, aimed at enhancing federal AI capabilities. The contract includes deployment through the General Services Administration and targets various domains including healthcare, care delivery, and research. This move aligns with broader government efforts to accelerate AI integration across federal operations.
