AI safety researchers from OpenAI, Anthropic, and other organizations are speaking out publicly against the “reckless” and “completely irresponsible” safety culture at xAI, the billion-dollar AI startup owned by Elon Musk.

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

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.

As Elon Musk contemplates the relationship between several of his companies, he said on social media that Tesla shareholders will vote on whether to invest in xAI.

AI released two AI "companions" on its Grok platform, a Japanese anime girl named "Ani" and an animated red panda called "Rudi."

Elon Musk's xAI startup is swimming in controversy after launching Grok 4, the latest version of its snarky AI chatbot. Last week, the company boasted that Grok 4 achieved higher scores than quite a few other large language models (LLMs) on various industry benchmarks.

The company told workers to download employee tracking software on their personal computers, prompting privacy concerns from some staff.
