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.

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.

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.

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

The takeaway, at least from a technical standpoint, is that Grok 4 is now firmly in frontier-model territory. That’s a meaningful shift for xAI, which just months ago was primarily known for its integration with X, the rechristened Twitter owned by Musk. xAI is clearly trying to be taken seriously as a legitimate AI research and enterprise company.

Grok 4 was trained on Colossus, a supercomputer that xAI launched in Memphis last year. The system featured 100,000 graphics cards when it came online in September. According to xAI, that number topped 200,000 in May and will eventually reach 1 million.

After Grok took a hard turn toward antisemitic earlier this week, many are probably left wondering how something like that could even happen.

Elon Musk’s xAI debuts Grok 4 series, including a premium SuperGrok, setting new benchmarks in academic AI performance.
