YouTube secretly used artificial intelligence to modify creators' videos without notification or consent, making subtle changes to their appearance[^1]. According to Rick Beato, who runs a YouTube channel with over 5 million subscribers, he noticed strange alterations in his videos - his hair looked different and it appeared he was wearing makeup[^1].

The AI modifications included sharpening skin in some areas while smoothing it in others, defining wrinkles in clothing more clearly, and causing subtle warping of features like ears[^1]. YouTuber Rhett Shull, who investigated the changes, said "If I wanted this terrible over-sharpening I would have done it myself... I think that deeply misrepresents me and what I do and my voice on the internet"[^1].

The unauthorized AI enhancements represent a concerning trend where artificial intelligence increasingly mediates reality before it reaches viewers, potentially eroding authentic connections between creators and their audiences[^1].
