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.

According to xAI's data, Grok 4 and Grok 4 Heavy essentially beat all other models, including OpenAI's o3, Google's Gemini 2.5 Pro, and Claude 4 Opus in various common AI benchmarks, though as one Redditor noticed, the competitors have been chosen selectively, likely to make Grok look better.

X CEO Linda Yaccarino announced she was stepping down from her position a day after the company's Grok artificial intelligence chatbot went haywire and began calling itself "MechaHitler." Yaccarino's departing message was positive and did not mention Tuesday's scandal.

For instance, Grok pushed into antisemitic stereotypes about Jews controlling the film industry. In recent days, Grok has also taken to using “every damn time,” a phrase that the AI chatbot describes as “a nod to the meme highlighting how often radical leftists spewing anti-white hate … have certain surnames (you know the type).”

A Turkish court has blocked access to Grok, the artificial intelligence chatbot developed by the Elon Musk-founded company xAI, after it generated responses that authorities said included insults to President Tayyip Erdogan.
