OpenAI released its latest AI image tool, o4 image generation, this Tuesday, and just a few hours after its launch, social media platforms were filled with the new trend: photographs transformed into a Ghibli-style—the popular Japanese animation studio—using ChatGPT.

Studio Ghibli-style images created with ChatGPT went viral after OpenAI launched its new o4 image generation tool. Social media users shared AI-generated portraits and memes that mimic iconic Japanese animation. The trend raised new copyright concerns, as experts question how closely AI tools mimic copyrighted styles and content.

Evan Brown, an intellectual property lawyer at the law firm Neal & McDevitt, told TechCrunch that style is not protected by copyright. However, to recreate these high-quality images, with the likeness they have, it is possible that OpenAI used millions of frames from Ghibli films to train the new o4 image generation. Sam Altman, OpenAI’s CEO, changed this profile picture to a Ghibli style version someone made of him. Altman also acknowledged the success of the new tool. “Images in chatGPT are way more popular than we expected (and we had pretty high expectations),” he wrote in a post. “Rollout to our free tier is unfortunately going to be delayed for a while.”

The debate over copyright and the use of new artificial intelligence tools is a hot topic with regulatory challenges. A few days ago, a U.S. federal judge ruled in favor of the artificial intelligence company Anthropic in response to a copyright lawsuit filed by several music producers.
