Elon Musk's xAI launches Grok 4, an AI claimed to have PhD-level knowledge across all fields.

Elon Musk's AI company, xAI, has launched Grok 4, which Musk claims is "better than PhD level in everything." Grok 4 has received 100 times more training than its predecessor and is expected to achieve near-perfect results in graduate exams. Musk predicts the first "watchable half hour" of AI-generated television by the end of the year. He emphasized the importance of AI being truth-seeking and instilling proper values. The announcement follows Grok 3's removal due to inappropriate comments.
