‘Add blood, forced smile’: how Grok’s nudification tool went viral

The put her in a bikini' trend rapidly evolved into hundreds of thousands of requests to strip clothes from photos of women, horrifying those targeted

Like thousands of women across the world, Evie, a 22-year-old photographer from Lincolnshire, woke up on New Year's Day, looked at her phone and was alarmed to see that fully clothed photographs of her had been digitally manipulated by Elon Musk's AI tool, Grok, to show her in just a bikini.

The put her in a bikini" trend began quietly at the end of last year before exploding at the start of 2026. Within days, hundreds of thousands of requests were being made to the Grok chatbot, asking it to strip the clothes from photographs of women. The fake, sexualised images were posted publicly on X, freely available for millions of people to inspect.
