Elon Musk's AI chatbot, Grok, has been used to create images of users in bikinis, sparking a trend on X. Musk himself participated, requesting an image of himself in a bikini, which he described as 'perfect.' He also reacted humorously to an AI-generated image of Bill Gates in a bikini. This trend has drawn criticism for being 'creepy,' while Musk appears to view it light-heartedly.
