Elon Musk’s live demo of Grok 4, the latest big-ticket model from his AI startup, began with high-intensity music, claims of a “ludicrous rate of progress,” and a lot of chatter on X about Grok’s scandal-filled week.

In a livestream with xAI colleagues, the billionaire entrepreneur described current AI systems as “primitive” and not for “serious” commercial use.

Grok, the chatbot created by Elon Musk’s xAI, began responding with violent posts this week after the company tweaked its system to allow it to offer users more “politically incorrect” answers.
