Tech giants, startups and academic labs are pumping out datasets and detectors in hopes of jump-starting the effort to create an automated system that can separate real videos, images and voice recordings from AI forgeries.

Why it matters: Algorithms that try to detect deepfakes lag behind the technology that creates them — a worrying imbalance given the technology's potential to stir chaos in an election or an IPO.

Driving the news: Dessa, the AI company behind the hyper-convincing fake Joe Rogan voice from earlier this summer, published a tool today for detecting deepfake audio — the kind that recently scammed a CEO out of $240,000.

  • The new detector, which Axios is reporting first, is open source, so anybody can go through the code for free to understand and potentially improve it.
  • But the company gets something out of it: The detector is built on a Dessa platform, which you have to download (without paying) to set it up.

The big picture: There's an all-hands scramble for better detectors, which generally require a lot of really good examples of deepfakes. Researchers use them to train algorithms that can tell if media was created by AI.

  • Yesterday, SUNY Albany deepfake expert Siwei Lyu released a dataset filed with celebrity deepfakes.
  • Earlier in the week, Google and Jigsaw — both owned by parent company Alphabet — released a large set of video deepfakes.
  • And earlier this month, Facebook, Microsoft and the Partnership on AI teamed up with academic researchers to release more deepfake videos — and offer a prize to the team that uses them to make the best detector.

Unlike these datasets, which allow researchers to cook up their own detectors, Dessa is releasing a pre-baked system — which has advantages and risks.

  • The company felt a responsibility to release an antidote after it made the realistic Rogan voice, says Ragavan Thurairatnam, Dessa's co-founder.
  • "I think it's inevitable that malicious actors are going to move much faster than those who want to stop it," he tells Axios. The free detector is a "starting point" for people to push detection forward.

But, but, but: Thurairatnam acknowledged that an open-source detector could help a particularly determined troll create new audio fakes that fool it. That's because generative AI systems can be trained to trick a specific detector.

  • He argues that the potential for creating better detectors outweighs the probability that someone will misuse Dessa's code.
  • But Lyu of SUNY Albany says there's some reason to worry. "In principle, such code will help both but probably more for making better generators."

Health care ruling saves Republicans from themselves

Illustration: Aïda Amer/Axios

The Supreme Court saved the health care system from imploding Thursday by dismissing a Republican challenge to the Affordable Care Act. But it also saved the GOP itself from another round of intraparty chaos.

Why it matters: Most GOP lawmakers privately admit (and some will even say publicly) they don't want to deal with health care again. The issue generally isn't a good one for them with voters — as they learned the hard way after they failed to repeal the ACA in 2017.

Fed chief's second-term audition

Federal Reserve Chairman Jerome Powell faces a long, hot summer audition for a second term, with senators watching and weighing his response to potential signs of inflation.

Why it matters: The financial system's chief is one of the most powerful in the world. President Biden hasn’t given any public indication whether he’ll renominate Powell, but Democrats close to the administration say there's a chance he'll make an announcement by Labor Day — well before Powell’s term ends next February.

Mapping China's growing global influence

Data: Atlantic Council; Map: Andrew Witherspoon/Axios

As of 1980, China was the most influential player in just one country: Albania. Now, China is the leading power across most of sub-Saharan Africa and Southeast Asia and is catching up to the U.S. in its own hemisphere.

What we’re reading: That's according to a new report from the University of Denver and the Atlantic Council that seeks to measure the influence countries have on each other, and in so doing offers a dramatic portrait of China's rise.
