TechnologyAdvice's Grant Harvey provides a deep dive on Grok 4, the "new" model from Elon Musk's AI company xAI.

As Grok fired off replies on X praising Hitler, the chatbot's parent company also recently got permission to emit 97 tons of carbon monoxide per year to keep it running.

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.

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.

Some X users suddenly became the subject of violent ideations by xAI’s flagship chatbot.

AI, made a splash with the release of Grok 4, and the announcement of a new ultra-premium subscription tier, SuperGrok Heavy.

Yaccarino announced her departure on X, saying that she is “immensely grateful” to Elon Musk for taking her on in 2023.

At the launch of Grok 4, the xAI presenters prompted the chatbot to predict the World Series. The AI said the Dodgers had a 21.6% chance of winning.
