No articles I can find yet but online chatter shows people talking about how tonight Grok is now heavily censored. Won't take uploaded images and put the woman in a bikini, etc. Won't make videos of women undressing into bikinis/underwear etc.
I tested it personally by uploading a pic of a woman and asking it draw her in a bikini and it was moderated. Uploaded to Imagine a woman already in a bikini and it refuses to make a video of literally anything (not even "woman reads a book", how sexist!)- even with no prompt it refuses. Asked it to draw a woman in a bikini and 1 attempt was moderated but another was generated.
All because Elon stuck his dick in crazy.
Grok to my knowledge has never allowed nudity on uploaded images, and nudity at all is behind a paywall and only on completely fake AI people.
Grok did allow bikinis and lingerie- the former is worn in public on the beach and shown on free TV in the daytime and prime time so it's not reasonable to call that "intimate". Go to a mall with a Victoria Secret store and you'll see huge pictures of women in lingerie facing the public hallways so I don't think you can call the "intimate" either.
And since the undressed bodies are completely fake I don't see WTF people are bitching about when the subjects are adults. I don't recall any outrage or countries banning Photoshop because they can be used to create fake nudes.
