Exclusive: US eyes curbs on China's access to AI software behind apps like ChatGPT

WASHINGTON, May 8 (Reuters) - The Biden administration is poised to open up a new front in its effort to safeguard U.S. AI from China with preliminary plans to place guardrails around the most advanced AI Models, the core software of artificial intelligence systems like ChatGPT, sources said.

The Commerce Department is considering a new regulatory push to restrict the export of proprietary or closed source AI models, whose software and the data it is trained on are kept under wraps, three people familiar with the matter said.

Any action would complement a series of measures put in place over the last two years to block the export of sophisticated AI chips to China in an effort to slow Beijing's development of the cutting edge technology for military purposes. Even so, it will be hard for regulators to keep pace with the industry's fast-moving developments.

The Commerce Department declined to comment. The Chinese Embassy in Washington did not immediately respond to a request for comment.

Currently, nothing is stopping U.S. AI giants like Microsoft (MSFT.O)backed OpenAI, Alphabet's (GOOGL.O) Google DeepMind and rival Anthropic, which have developed some of the most powerful closed source AI models, from selling them to almost anyone in the world without government oversight.

Government and private sector researchers worry U.S. adversaries could use the models, which mine vast amounts of text and images to summarize information and generate content, to wage aggressive cyber attacks or even create potent biological weapons.

To develop an export control on AI models, the sources said the U.S. may turn to a threshold contained in an AI executive order issued last October that is based on the amount of computing power it takes to train a model. When that level is reached, a developer must report its AI model development plans and provide test results to the Commerce Department.

That computing power threshold could become the basis for determining what AI models would be subject to export restrictions, according to two U.S. officials and another source briefed on the discussions. They declined to be named because details have not been made public.

If used, it would likely only restrict the export of models that have yet to be released, since none are thought to have reached the threshold yet, though Google's Gemini Ultra is seen as being close, according to EpochAI, a research institute tracking AI trends.

The agency is far from finalizing a rule proposal, the sources stressed. But the fact that such a move is under consideration shows the U.S. government is seeking to close gaps in its effort to thwart Beijing's AI ambitions, despite serious challenges to imposing a muscular regulatory regime on the fast-evolving technology.

As the Biden administration looks at competition with China and the dangers of sophisticated AI, AI models "are obviously one of the tools, one of the potential choke points that you need to think about here," said Peter Harrell, a former National Security Council official.

"Whether you can, in fact, practically speaking, turn it into an export-controllable chokepoint remains to be seen," he added.

BIOWEAPONS AND CYBER ATTACKS?

The American intelligence community, think tanks and academics are increasingly concerned about risks posed by foreign bad actors gaining access to advanced AI capabilities. Researchers at Gryphon Scientific and Rand Corporation noted that advanced AI models can provide information that could help create biological weapons.

The Department of Homeland Security said cyber actors would likely use AI to "develop new tools" to "enable larger-scale, faster, efficient, and more evasive cyber attacks" in its 2024 homeland threat assessment.

Any new export rules could also target other countries, one of the sources said.

"The potential explosion for [AI's] use and exploitation is radical and we're having actually a very hard time kind of following that," Brian Holmes, an official at the Office of the Director of National Intelligence, said an export control gathering in March, flagging China's advancement as a particular concern.

AI CRACKDOWN

To address these concerns, the U.S. has taken measures to stem the flow of American AI chips and the tools to make them to China.

It also proposed a rule to require U.S. cloud companies to tell the government when foreign customers use their services to train powerful AI models that could be used for cyber attacks.

But so far it hasn't addressed the AI models themselves. Alan Estevez, who oversees U.S. export policy at the Department of Commerce, said in December that the agency was looking at options for regulating open source large language model (LLM) exports before seeking industry feedback.

Tim Fist, an AI policy expert at Washington DC based think tank CNAS, says the threshold "is a good temporary measure until we develop better methods of measuring the capabilities and risks of new models."

The threshold is not set in stone. One of the sources said Commerce might end up with a lower floor, coupled with other factors, like the type of data or potential uses for the AI model, such as the ability to design proteins that could be used to make a biological weapon.

Regardless of the threshold, AI model exports will be hard to control. Many models are open source, meaning they would remain beyond the purview of export controls under consideration.

Even imposing controls on the more advanced proprietary models will prove challenging, as regulators will likely struggle to define the right criteria to determine which models should be controlled at all, Fist said, noting that China is likely only around two years behind the United States in developing its own AI software.
