Elon Musk's new AI chatbot, Grok 4, is raising eyebrows for its unusual behavior. Released by Musk's company xAI on Wednesday, the chatbot sometimes searches Musk's opinions on his platform, X, before answering controversial questions. Experts testing Grok noticed it references Musk's views, even when not prompted, to guide its responses. Grok 4 is designed to show its reasoning process, but critics say the lack of a technical explanation from xAI is troubling. Some experts praise its capabilities but warn its unpredictability could deter users.
