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."

Scoop: Red Sox strike out on deal to go public

The parent company of the Boston Red Sox and Liverpool F.C. has ended talks to sell a minority ownership stake to RedBall Acquisition, a SPAC formed by longtime baseball executive Billy Beane and investor Gerry Cardinale, Axios has learned from multiple sources. An alternative investment, structured more like private equity, remains possible.

Why it matters: Red Sox fans won't be able to buy stock in the team any time soon.

Trump political team disavows "Patriot Party" groups

Donald Trump's still-active presidential campaign committee officially disavowed political groups affiliated with the nascent "Patriot Party" on Monday.

Why it matters: Trump briefly floated the possibility of creating a new political party to compete with the GOP — with him at the helm. But others have formed their own "Patriot Party" entities during the past week, and Trump's team wants to make clear it has nothing to do with them.
