Nvidia Corp, the world's leading designer of computer chips used in creating artificial intelligence, on Monday showed new research that explains how AI can be used to improve chip design.

The process of designing a chip involves deciding where to place tens of billions of tiny on-off switches called transistors on a piece of silicon to create working chips. The exact placement of those transistors has a big impact on the chip's cost, speed and power consumption.

Chip design engineers use complex design software from firms like Synopsys Inc and Cadence Design Systems Inc to help them optimize the placement of those transistors.

On Monday, Nvidia released a paper showing that it could use a combination of artificial intelligence techniques to find better ways to place big groups of transistors. The paper aimed to improve on a 2021 paper by Alphabet Inc's Google, whose findings later became the subject of controversy.

The Nvidia research took an existing effort developed by University of Texas researchers using what is called reinforcement learning and added a second layer of artificial intelligence on top of it to get even better results.

Nvidia chief scientist Bill Dally said the work is important because chip manufacturing improvements are slowing with per-transistor costs in new generations of chip manufacturing technology now higher than previous generations.

That goes against the famous prediction by Intel Corp co-founder Gordon Moore that chips would always get cheaper and faster.

"You're no longer actually getting an economy from that scaling," Dally said. "To continue to move forward and to deliver more value to customers, we can't get it from cheaper transistors. We have to get it by being more clever on the design."

The State Department is warning US diplomats of attempts to impersonate Secretary of State Marco Rubio and possibly other officials using technology driven by artificial intelligence, according to two senior officials and a cable sent last week to all embassies and consulates.

The warning came after the department discovered that an impostor posing as Rubio had attempted to reach out to at least three foreign ministers, a US senator and a governor, according to the July 3 cable, which was first reported by The Washington Post.

The recipients of the scam messages, which were sent by text, Signal and voice mail, were not identified in the cable, a copy of which was shared with The Associated Press.

“The State Department is aware of this incident and is currently investigating the matter,” it said. “The department takes seriously its responsibility to safeguard its information and continuously takes steps to improve the department’s cybersecurity posture to prevent future incidents.”

It declined to comment further due to “security reasons” and the ongoing investigation.

One of the officials said the hoaxes had been unsuccessful and “not very sophisticated.” Nonetheless, the second official said the department deemed it “prudent” to advise all employees and foreign governments, particularly as efforts by foreign actors to compromise information security increase.

The officials were not authorized to discuss the matter publicly and spoke on condition of anonymity.

“There is no direct cyber threat to the department from this campaign, but information shared with a third party could be exposed if targeted individuals are compromised,” the cable said.

The FBI warned in a public service announcement this past spring of a “malicious text and voice messaging campaign” in which unidentified “malicious actors” have been impersonating senior US government officials.

The scheme, according to the FBI, has relied on text messages and AI-generated voice messages that purport to come from a senior US official and that aim to dupe other government officials as well as the victim’s associates and contacts.

It is the second high-level Trump administration official to face such AI-driven impersonation.

The government was investigating after elected officials, business executives and other prominent figures received messages from someone impersonating President Donald Trump’s chief of staff, Susie Wiles. Text messages and phone calls went out from someone who seemed to have gained access to the contacts in Wiles’ personal cellphone, The Wall Street Journal reported in May.

Some of those who received calls heard a voice that sounded like Wiles, which may have been generated by artificial intelligence, according to the newspaper. The messages and calls were not coming from Wiles’ number, the report said.
