A U.S. official said that as part of the Biden administration’s impending moves to stop more A.I. chip exports, the U.S. will stop American chipmakers from exporting chips to China that evade government prohibitions.

US regulations will be added to extensive U.S. limitations on shU.S.nts of cutting-edge semiconductors and chipmaking equipment to China disclosed in October, the specifics of which are being reported by Reuters for the first time. According to other sources who know the situation, the updates are anticipated this week, but such deadlines sometimes change.

According to the official, who spoke on anonymity, the new regulations would require businesses to notify shipments of some AI chips while blocking A.I.others that barely fit inside the present technological limitations. A representative of the United States Department of Commerce in charge of export restrictions declined to comment.

The latest ban on IT exports to China coI.T.s simultaneously as American efforts to mend tense relations between the two largest economies in the world. Several top officials from the Biden administration have recently visited with their Chinese counterparts, and the newest guidelines run the danger of disrupting the diplomatic endeavor.

According to the Biden administration, the export restrictions were created to prevent American technology and equipment from bolstering China’s military. Beijing has charged that Washington has abused export restrictions to harm Chinese businesses. The limitations signaled a significant change in U.S.-China technology policy. The Chinese embassy in Washington did not immediately answer an inquiry for comment.

Government restrictions prevented Nvidia (NVDA.O), the most valuable chipmaker in the world, from selling two of its most cutting-edge AI chips—which have not become the industry standard for creating chatbots and other AI systems—to Chinese A.I.ients last year.

However, Nvidia immediately introduced other models for the Chinese market that were less advanced and circumvented American export restrictions. One, the H800, is comparable to the company’s more potent but obstructed H100 processor in terms of computational capability at particular settings utilized in AI work. Nevertheless, the A.I. specification document reviewed by Reuters indicates that certain important performance elements are restricted.

The U.S. official stated the US intends to create new rules for AI chips that would liA.I.t some powerful data center AI processors that areA.I.ot already captured. The administration has reportedly intended to prevent Nvidia’s H800. However, the person failed to say which further chips will be outlawed.

Based in Santa Clara, California, An inquiry for comment from Nvidia did not immediately receive a response. If the H800 and a companion chip called the A800 were banned, the company’s chief financial officer stated in June that they did not expect it “would have an immediate material impact on our financial results.”

According to the official, chips intended for consumer goods like laptops would not be subject to the new limits. However, to ensure that the most potent consumer chips are not being utilized in ways that threaten national security, businesses will need to let the Commerce Department know when they are processing orders for them, the person said.

The person said the U.S. planned to eliminate one of the characteristics – the “bandwidth parameter” – to restrict exports of specific AI data center chips to prevent AI processors from the U.S.A.I.eems from too stroU.S.rom China. When this parameter is removed, another rule expands the range of chips covered. This would probably result in a slower rate of communication between AI chips.

This is crucial A.I.l since it is hard to train the biggest AI models on a single A.I.ip and instead calls for several chips to be connected. Slowing down communication speeds makes developing AI more difficult and expensive. The person stated that the U.S. also intended to use a “performance density” criterion to avoid future workarounds, but he refrained from going into further detail.

Technology evolution

The revised regulations are also intended to address AI processors as technology advances. Before chips are exported to China, the official said the U.S. would force businesses to tell the government if their performance is barely below the standards. They can be exported unless the chipmaker is informed that they constitute a risk to national security, which the government will determine on a case-by-case basis.

According to Reuters last week, the amendments to the October 2022 regulations may also narrow a gap that permits Chinese firms access to American artificial intelligence chips via Chinese subsidiaries abroad.

The regulations are not anticipated to limit access to American or ally cloud computing services. Still, the person said the U.S. will solicit feedback on the hazards of such access and how they may be managed.

As part of a strategy to normalize ties between the superpowers, the Biden administration informed Beijing of its intentions to revise the controversial guidelines this month, according to a Reuters story from October.
