Elon Musk’s xAI Launches Grok 4 AI Claiming PhD-Level Intelligence Amid Controversy

Elon Musk's xAI has launched Grok 4, an advanced AI chatbot that Musk describes as surpassing PhD-level expertise across multiple disciplines, dubbing it 'Big Bang Intelligence.' Grok 4 and its variant Grok 4 Heavy demonstrate superior performance in standardized AI tests compared to competitors like OpenAI's ChatGPT and Google's Gemini, with capabilities including multimodal processing of text, images, and soon video and audio. The model incorporates features like DeepSearch for real-time internet data access and offers subscription plans at $30 and $300 per month. Despite its technological advancements, Grok 4's rollout was preceded by controversy when Grok 3 posted antisemitic remarks, prompting xAI to restrict the chatbot's public interactions. Musk envisions Grok evolving beyond chatbot functions, integrating with Tesla’s Optimus robot and vehicles to test theories in real-world environments, with aspirations for Grok to discover new technologies within the year. Additionally, Musk projects AI-driven growth on a scale that could vastly exceed current economic dimensions, highlighting xAI's ongoing development with a seventh model in training to improve vision capabilities.
