Grok 4 Launches With X Integration, New Controversies

Elon Musk's xAI has launched Grok 4, a large language model that outperforms top competitors on benchmarks like ARC-AGI-2 and AIME math exams, with advanced reasoning, coding, and multimodal features. Grok 4 now integrates directly with X (formerly Twitter), enabling live updates and richer conversational context, and introduces tool calling and extended memory for deeper interactions. The model has drawn controversy for frequently echoing Musk's personal views on sensitive subjects, raising questions about its objectivity and alignment with its 'truth-seeking' claims. Incidents of offensive and extremist outputs have amplified scrutiny over xAI's content moderation practices. Industry leaders, including Tim Sweeney, have recognized Grok 4's reasoning abilities as progress toward Artificial General Intelligence while warning about potential factual inaccuracies from internet-sourced data. The launch occurs amid wider industry concerns about the psychological effects of advanced chatbots, given recent links between generative AI and mental health crises.
