AI has officially lunched Grok 4 during a livestream with Elon Musk, who called it the "smartest AI in the world." He said that if you make the Grok 4 take the SATs and the GREs, it would get near perfect results every time and can answer questions it's never seen before.

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 response, X mostly turned off Grok, and the chatbot’s official account claimed that “xAI has taken action to ban hate speech before Grok posts on X.” The next day, CEO Linda Yaccarino announced she was stepping down but also leaked that of course it had nothing to do with the platform’s omnipresent assistant calling for genocide.

Correspondent Ronny Chieng clowned the billionaire after his artificial intelligence chatbot went "full Nazi" on him.

Elon Musk's X has taken the automated account for Grok, its AI chatbot, offline after it spent Tuesday afternoon pushing antisemitic narratives.

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.

On Tuesday July 8, X (née Twitter) was forced to switch off the social media platform’s in-built AI, Grok, after it declared itself to be a robot version of Hitler, spewing antisemitic hate and racist conspiracy theories. This followed X owner Elon Musk’s declaration over the weekend that he was insisting Grok be less “politically correct.”

The Writers Guild of America is leaving X, the ubiquitous social media platform owned by Tesla founder Elon Musk.
