Chinese internet authorities summoned Nvidia on Thursday to discuss "serious security issues" over some of its artificial intelligence (AI) chips, as the US technology giant finds itself entangled in trade tensions between Beijing and Washington.

Nvidia is a world-leading producer of AI semiconductors, but the United States effectively restricts which chips it can export to China on national security grounds, AFP reported.

A key issue has been Chinese access to the "H20", a less powerful version of Nvidia's AI processing units that the company developed specifically for export to China.

Chinese internet authorities summoned Nvidia on Thursday to discuss "serious security issues" over some of its artificial intelligence (AI) chips, as the US technology giant finds itself entangled in trade tensions between Beijing and Washington.

Nvidia is a world-leading producer of AI semiconductors, but the United States effectively restricts which chips it can export to China on national security grounds.

A key issue has been Chinese access to the "H20", a less powerful version of Nvidia's AI processing units that the company developed specifically for export to China.

The California-based firm said earlier this month that it would resume H20 sales to China after Washington pledged to remove licensing curbs that had halted exports.

But the firm still faces obstacles -- US lawmakers have proposed plans to require Nvidia and other manufacturers of advanced AI chips to include built-in location tracking capabilities.

And on Thursday, Beijing's top internet regulator said it had summoned Nvidia representatives to discuss recently discovered "serious security issues" involving the H20.

The Cyberspace Administration of China said it had asked Nvidia to "explain the security risks of vulnerabilities and backdoors in its H20 chips sold to China and submit relevant supporting materials".

The statement posted on social media noted that, according to US experts, location tracking and remote shutdown technologies for Nvidia chips "are already matured".

The announcement marked the latest complication for Nvidia in selling its advanced products in the key Chinese market, where it is in increasingly fierce competition with homegrown technology firms.

- Nvidia committed -

CEO Jensen Huang said during a closely watched visit to Beijing this month that his firm remained committed to serving local customers.

Huang said he had been assured during talks with top Chinese officials during the trip that the country was "open and stable".

"They want to know that Nvidia continues to invest here, that we are still doing our best to serve the market here," he said.

Nvidia this month became the first company to hit $4 trillion in market value -- a new milestone in Wall Street's bet that AI will transform the global economy.

New hurdles to the firm's operation in China come as the country's economy wavers, beset by a years-long property sector crisis and heightened trade headwinds under US President Donald Trump.

Chinese President Xi Jinping has called for the country to enhance self-reliance in certain areas deemed vital for national security -- including AI and semiconductors -- as tensions with Washington mount.

The country's firms have made great strides in recent years, with Huang praising their "super-fast" innovation during his visit to Beijing this month.

German turbine maker Siemens Energy said Wednesday that its quarterly profits had almost tripled as the firm gains from surging demand for electricity driven by the artificial intelligence boom.

The company's gas turbines are used to generate electricity for data centers that provide computing power for AI, and have been in hot demand as US tech giants like OpenAI and Meta rapidly build more of the sites.

Net profit in the group's fiscal first quarter, to end-December, climbed to 746 million euros ($889 million) from 252 million euros a year earlier.

Orders -- an indicator of future sales -- increased by a third to 17.6 billion euros.

The company's shares rose over five percent in Frankfurt trading, putting the stock up about a quarter since the start of the year and making it the best performer to date in Germany's blue-chip DAX index.

"Siemens Energy ticked all of the major boxes that investors were looking for with these results," Morgan Stanley analysts wrote in a note, adding that the company's gas turbine orders were "exceptionally strong".

US data center electricity consumption is projected to more than triple by 2035, according to the International Energy Agency, and already accounts for six to eight percent of US electricity use.

Asked about rising orders on an earnings call, Siemens Energy CEO Christian Bruch said he thought the first-quarter figures were not "particularly strong" and that further growth could be expected.

"Demand for gas turbines is extremely high," he said. "We're talking about 2029 and 2030 for delivery dates."

Siemens Energy, spun out of the broader Siemens group in 2020, said last week that it would spend $1 billion expanding its US operations, including a new equipment plant in Mississippi as part of wider plans that would create 1,500 jobs.

Its shares have increased over tenfold since 2023, when the German government had to provide the firm with credit guarantees after quality problems at its wind-turbine unit.

Instagram chief Adam Mosseri is to be called to testify Wednesday in a Los Angeles courtroom by lawyers out to prove social media is dangerously addictive by design to young, vulnerable minds.

YouTube and Meta -- the parent company of Instagram and Facebook -- are defendants in a blockbuster trial that could set a legal precedent regarding whether social media giants deliberately designed their platforms to be addictive to children.

Rival lawyers made opening remarks to jurors this week, with an attorney for YouTube insisting that the Google-owned video platform was neither intentionally addictive nor technically social media.

"It's not social media addiction when it's not social media and it's not addiction," YouTube lawyer Luis Li told the 12 jurors during his opening remarks.

The civil trial in California state court centers on allegations that a 20-year-old woman, identified as Kaley G.M., suffered severe mental harm after becoming addicted to social media as a child.

She started using YouTube at six and joined Instagram at 11, before moving on to Snapchat and TikTok two or three years later.

The plaintiff "is not addicted to YouTube. You can listen to her own words -- she said so, her doctor said so, her father said so," Li said, citing evidence he said would be detailed at trial.

Li's opening arguments followed remarks on Monday from lawyers for the plaintiffs and co-defendant Meta.

On Monday, the plaintiffs' attorney Mark Lanier told the jury YouTube and Meta both engineer addiction in young people's brains to gain users and profits.

"This case is about two of the richest corporations in history who have engineered addiction in children's brains," Lanier said.

"They don't only build apps; they build traps."

But Li told the six men and six women on the jury that he did not recognize the description of YouTube put forth by the other side and tried to draw a clear line between YouTube's widely popular video app and social media platforms like Instagram or TikTok.

YouTube is selling "the ability to watch something essentially for free on your computer, on your phone, on your iPad," Li insisted, comparing the service to Netflix or traditional TV.

Li said it was the quality of content that kept users coming back, citing internal company emails that he said showed executives rejecting a pursuit of internet virality in favor of educational and more socially useful content.

- 'Gateway drug' -

Stanford University School of Medicine professor Anna Lembke, the first witness called by the plaintiffs, testified that she views social media, broadly speaking, as a drug.

The part of the brain that acts as a brake when it comes to having another hit is not typically developed before a person is 25 years old, Lembke, the author of the book "Dopamine Nation," told jurors.

"Which is why teenagers will often take risks that they shouldn't and not appreciate future consequences," Lembke testified.

"And typically, the gateway drug is the most easily accessible drug," she said, describing Kaley's first use of YouTube at the age of six.

The case is being treated as a bellwether proceeding whose outcome could set the tone for a wave of similar litigation across the United States.

Social media firms face hundreds of lawsuits accusing them of leading young users to become addicted to content and suffer from depression, eating disorders, psychiatric hospitalization, and even suicide.

Lawyers for the plaintiffs are borrowing strategies used in the 1990s and 2000s against the tobacco industry, which faced a similar onslaught of lawsuits arguing that companies knowingly sold a harmful product.

OpenAI Starts Testing Ads in ChatGPT

OpenAI has begun placing ads in the basic versions of its ChatGPT chatbot, a bet that users will not mind the interruptions as the company seeks revenue as its costs soar.

"The test will be for logged-in adult users on the Free and Go subscription tiers" in the United States, OpenAI said Monday. The Go subscription costs $8 in the United States.

Only a small percentage of its nearly one billion users pay for its premium subscription services, which will remain ad-free.

"Ads do not influence the answers ChatGPT gives you, and we keep your conversations with ChatGPT private from advertisers," the company said.

Since ChatGPT's launch in 2022, OpenAI's valuation has soared to $500 billion in funding rounds -- higher than any other private company. Some analysts expect it could go public with a trillion-dollar valuation.

But the ChatGPT maker burns through cash at a furious rate, mostly on the powerful computing required to deliver its services.

Its chief executive Sam Altman had long expressed his dislike for advertising, citing concerns that it could create distrust about ChatGPT's content.

His about-face garnered a jab from its rival Anthropic over the weekend, which made its advertising debut at the Super Bowl championship with commercials saying its Claude chatbot would stay ad-free.
