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.

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 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.

The release comes months after the AI startup launched its previous iteration, suggesting an ongoing lightning pace of AI development.

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.

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.

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 launched its chatbot in 2023 as an alternative to other "woke" bots. Here's what you need to know about Grok.
