The AI startup behind the controversial Grok chatbot is in early talks to raise billions, with backing from Saudi Arabia’s PIF.

Elon Musk and xAI employee announced on Wednesday night the launch of the startup's next flagship AI model, Grok 4.

Earlier today, Grok showed me how to tell if someone is a “good scientist,” just from their demographics. For starters, according to a formula devised by Elon Musk’s chatbot, they have to be a white, Asian, or Jewish man.

According to the Financial Times, xAI plans to spend $18 billion on expanding its compute infrastructure. The company trains its models using a supercomputer called Colossus that is located in Memphis. Earlier this year, Musk stated that xAI plans to increase the number of graphics cards in the system from 200,000 to 1 million.
