Officials from several U.S. federal agencies have recently raised concerns about the safety and reliability of Elon Musk's xAI artificial intelligence tool, according to the Wall Street Journal. These concerns highlight ongoing divisions within the U.S. government regarding which AI models should be adopted. According to Jin10, these warnings were issued before the Pentagon's decision this week to place xAI at the core of some of the country's most sensitive and classified operations. The decision includes allowing the use of its chatbot 'Grok' in confidential environments.
