David Lammy has said that US vice president JD Vance agrees that sexualised AI-generated deepfakes - such as those made using Elon Musk's Grok - are "entirely unacceptable".

The deputy prime minister told The Guardian that Mr Vance expressed concern about how artificial intelligence was being used to create "hyper-pornographied slop" online when they met in Washington on Thursday.

After discussing Greenland, Mr Lammy said: "I also raised with him the Grok issue and the horrendous, horrific situation in which this new technology is allowing deepfakes and the manipulation of images of women and children, which is just absolutely abhorrent.

"He agreed with me that it was entirely unacceptable."

Since the start of the new year, X users - mainly women - have reported that accounts have used Grok to generate images of them without clothing.

And earlier this week, the Internet Watch Foundation reported that criminals have been using Grok to create child sexual abuse imagery.

X faces backlash over deepfakes

X appeared to have changed Grok's settings in response, with a message displayed by the tool saying image editing and generation had been limited to paid subscribers.

'Despicable' Grok image rules changed: But is it enough?

But these changes were described as "insulting" by Downing Street, while Prime Minister Sir Keir Starmer said that X needed "to get a grip of" Grok, and he had asked media regulator Ofcom for "all options to be on the table".

Appearing defiant, Musk later shared one X user's post criticising the Labour government for apparently focusing on his platform, pointing to claims of other AI programmes creating non-sexualised images of women in bikinis.
