OpenAI's ChatGPT-4o image generator has seen a surge in user engagement, with over 150 million active users reported in April. The tool allows the creation of images in various styles, including those resembling Studio Ghibli animations and Barbie dolls. The AI Barbie doll trend, where users transform themselves into action figures with personalized accessories, has gone viral. Republican congresswoman Marjorie Taylor Greene shared an image of her AI-generated Barbie doll, highlighting the trend's popularity. The 'Ghiblification' trend, recreating images in the style of Studio Ghibli, has also gained traction. However, this has raised concerns about potential copyright violations, with Studio Ghibli's co-founder Hayao Miyazaki expressing strong disapproval of AI image generation technology. The increased demand for image generation has put significant pressure on OpenAI's infrastructure. CEO Sam Altman noted that the company's GPUs are 'melting' due to high usage, urging users to moderate their use of the image generator to alleviate the strain on the system.
