Elon Musk on Wednesday unveiled Grok 4, a new version of his X platform's AI chatbot. The update comes a day after the bot posted antisemitic content on the social media network. Musk introduced the new model in a livestream on X late Wednesday, calling Grok 4 "the smartest AI in the world."

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.

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

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.

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

AI owner Elon Musk made some big claims about Grok’s capability, saying it was “better than PhD level in every subject.”

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.

A day after Grok 3 was taken offline after its unhinged anti-Semitic spree, Elon Musk-led xAI launched Grok 4 in about a 48 minutes demo livestream. Introducing Grok 4, the world's most powerful AI model. Watch the livestream now: https://t.co/59iDX5s2ck — xAI (@xai) July 10, 2025
