Nvidia drops after government limits exports of H20 chips to China

The government is now restricting its exports of Nvidia’s H20 chips to China — chips the company had made to bypass previous restrictions on Chinese chip exports, Bloomberg reports.

Shares of the company fell 6.2% in recent after-hours trading.

The move is part of a government effort to address concerns that “the covered products may be used in, or diverted to, a supercomputer in China.” Nvidia said the restriction could cost it $5.5 billion in charges related to the H20 line.

Yesterday, US Immigration and Customs Enforcement (ICE) officers stopped and arrested two workers from Meta’s massive Hyperion data center construction site in Richland Parish, Louisiana.

According to the Richland Parish Sheriff’s Office, two dump truck drivers were stopped and arrested as part of a traffic stop as they headed to the construction site where thousands of people are working.

Bloomberg reports that unmarked vehicles at the perimeter of the construction site were stopping and checking the identification of workers. The Sheriff’s Office said ICE agents did not enter the Meta site at any time.

Two cofounders leave Thinking Machines Lab to return to OpenAI

A group of researchers have left Mira Murati’s Thinking Machines Lab to go back to OpenAI. Fidji Simo, OpenAI’s head of apps, posted on X that Thinking Machines cofounders Barret Zoph and Luke Metz, along with Sam Schoenholz, will be returning to the company.

In October, Thinking Machines cofounder Andrew Tulloch left to work for Meta.

Thinking Machine Labs was cofounded by Murati, a former OpenAI executive, and the startup has been raising large amounts of money, reportedly with a $50 billion valuation.

X says it’s stopping Grok from putting real people in bikinis on X

After public and government uproar over sexualized deepfakes of women and children, X’s Safety account posted Wednesday evening that it is no longer allowing the Grok account on X to generate “images of real people in revealing clothing such as bikinis.” The xAI-owned company also said it restricted image generation and editing via Grok on X more broadly to paid subscribers.

For what it’s worth, a subscriber reply to X Safety’s post asking Grok to put the tweet “in a bikini” prompted the chatbot to post an image of a woman in a bikini — though she does not appear to be a real person. I’m not a paid X subscriber but, in the process of reporting this piece, I was able to edit the image to be “younger” and “17 years old.”

The post also did not address what the changes mean for Grok’s stand-alone app, which currently ranks No. 5 among free apps in Apple’s App Store. Previous reporting from NBC News found that users could also still generate offensive images using the app.

Tesla and xAI CEO Elon Musk, for his part, said Wednesday that he was “not aware of any naked underage images generated by Grok.”
