LONDON — AI fakery is quickly becoming one of the biggest problems confronting us online. Deceptive pictures, videos and audio are proliferating as a result of the rise and misuse of generative artificial intelligence tools.

With AI deepfakes cropping up almost every day, depicting everyone from Taylor Swift to Donald Trump to Katy Perry attending the Meta Gala, it's getting harder to tell what's real from what's not. Video and image generators like DALL-E, Midjourney and OpenAI’s Sora make it easy for people without any technical skills to create deepfakes — just type a request and the system spits it out.

These fake images might seem harmless. But they can be used to carry out scams and identity theft or propaganda and election manipulation.

Here is how to avoid being duped by deepfakes:

In the early days of deepfakes, the technology was far from perfect and often left telltale signs of manipulation. Fact-checkers have pointed out images with obvious errors, like hands with six fingers or eyeglasses that have differently shaped lenses.

But as AI has improved, it has become a lot harder. Some widely shared advice — such as looking for unnatural blinking patterns among people in deepfake videos — no longer holds, said Henry Ajder, founder of consulting firm Latent Space Advisory and a leading expert in generative AI.

Still, there are some things to look for, he said.

A lot of AI deepfake photos, especially of people, have an electronic sheen to them, “an aesthetic sort of smoothing effect” that leaves skin “looking incredibly polished,” Ajder said.

He warned, however, that creative prompting can sometimes eliminate this and many other
