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

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

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.

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.

Grok was developed by Musk’s xAI and pitched as alternative to “woke AI” interactions from rival chatbots like Google’s Gemini, or OpenAI’s ChatGPT.

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.

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

Grok, an artificial intelligence chatbot developed by Elon Musk s company xAI, made a series of comments this week praising Hitler and criticizing Jews, which were soon deleted

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