Sora is even fooling human deepfake detectors

"It used to be that artificial intelligence would leave behind helpful clues that an image it produced was not, in fact, real. Previous generations of the technology might give a person an extra finger or even an additional limb. Teeth could look odd and out of place, and skin could render overly blushed, like something out of Pixar. Multiple dimensions could befuddle our models, which struggled to represent the physical world in a sensical way:"

"That's no longer the case. While there are still some analog ways to detect that the content we see was created with the help of AI, the implicit visual tip-offs are, increasingly, disappearing. The limited release of Sora 2, OpenAI's latest video-generation model, has only hastened this development, experts at multiple AI detection companies tell Fast Company -meaning we may soon come to be entirely dependent on digital and other technical tools to wade through AI slop."

""Even [for] analysts like me who saw the evolution of this industry, it's really hard, especially on images," Francesco Cavalli, cofounder of one of those firms, Sensity AI, tells Fast Company. "The shapes, the colors, and the humans are perfect. So without the help of a tool now, it's almost impossible for the average internet user to understand whether an image or a video or a piece of audio is AI-generated or not.""

Early AI-generated visuals frequently displayed clear artifacts such as extra fingers, misplaced teeth, exaggerated skin tones, and dimension errors that revealed their artificial origin. Those visible clues are fading as recent models render shapes, colors, and human figures with convincing realism. The limited release of Sora 2, a new video-generation model, has accelerated the trend toward indistinguishable imagery and reduced the effectiveness of casual visual inspection. Average internet users increasingly cannot tell whether images, videos, or audio are AI-generated without specialized digital tools. The shift raises concerns for institutions that must protect likenesses and identities from theft and misappropriation while researchers search for new telltale signs.
