Elon Musk introduced Grok 4, the latest AI model from his company xAI, designed to rival platforms like OpenAI and Google. Musk claims Grok 4 demonstrates postgraduate-level expertise across various disciplines, although the company has yet to release a technical report detailing its capabilities. Grok 4 is available via subscription, with a premium version offered at a higher cost. Despite its advanced claims, the model has faced criticism for antisemitic posts made by its chatbot, prompting xAI to address hate speech issues. The announcement follows a wave of investment in generative AI technologies and aims to optimize AI systems for truth-seeking and ethical behavior, according to Musk.
