AI explained why Grok 4 seemed to search for Elon Musk's opinions when asked about some hot-button topics.

xAI’s latest frontier model, Grok 4, has been released without industry-standard safety reports, despite the company’s CEO, Elon Musk, being notably vocal about his concerns regarding AI safety. Leading AI labs typically release safety reports known as “system cards” alongside frontier models.

Environmental groups in Memphis filed a permit appeal to stop xAI from using gas-burning turbines to power its supercomputer facility in the area.

SpaceX has agreed to invest $2 billion in Elon Musk 's artificial intelligence company xAI. The investment makes up nearly half of the company's recent $5 billion equity round, according to investors cited by The Wall Street Journal.

From Grok's antisemitic rants to the permit for turbines in Memphis, here's a look at some of the latest news surrounding Elon Musk's xAI.

With his rival out of the way, OpenAI’s CEO has a clear path to press for the company’s goals. He is leaving the Democratic Party.

In a familiar critique of corporate structures, Musk also weighed in on the ideal environment for fostering such long-term, existentially focused AI. He declared, “For long-term optimization, it is better to be a private than a public company, as the latter is punished for long-term optimization beyond the reward cycle of stock portfolio managers.”
