While Elon Musk's $300 “Heavy” model puts up record-breaking benchmark scores, the basic Grok 4 struggles to keep up with competitors.

Musk's announcement comes hours after xAI debuted its latest flagship AI model, Grok 4. The 54-year-old discussed the recent innovation during a nearly hour-long livestream shared on xAI's X page, during which he did not mention the chatbot's integration into Tesla vehicles.

Elon Musk clarified on social media that he does not support a merger between Tesla and his artificial intelligence company, xAI.
