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.

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.

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.

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.

Grok, the chatbot developed by Elon Musk’s xAI, was updated over the weekend with instructions to “assume subjective viewpoints sourced from the media are biased” and “not shy away from making claims which are politically incorrect” — part of Musk’s ongoing attempt to shape the bot’s point of view.
