ChatGPT creators OpenAI have introduced rate limits after a viral social media trend that saw nearly everything “Ghiblifyied” — turned into AI art in the style of the famous Japanese animation studio. 

OpenAI CEO Sam Altman was one of the first to take part in the trend, posting a portrait of himself generated by the model on March 25 but said in a subsequent post two days later that all image requests have started to tax the firm’s infrastructure.

“It’s super fun seeing people love images in ChatGPT but our GPUs are melting. We are going to temporarily introduce some rate limits while we work on making it more efficient,” he said.

“Also, we are refusing some generations that should be allowed; we are fixing these as fast we can,” he added.

OpenAI launched the upgraded image generation offering in ChatGPT-4o on March 25, resulting in users splashing images across social media in the art style of Studio Ghibli — known for its anime films Spirited Away and My Neighbor Totoro.

Altman didn’t give a definitive timeline on how long the rate limits would last but said, “Hopefully, it won’t be long! ChatGPT free tier will get three generations per day soon.”

Rate limits are generally applied to help OpenAI manage the aggregate load on its infrastructure, according to OpenAI.

“If requests to the API increase dramatically, it could tax the servers and cause performance issues. By setting rate limits, OpenAI can help maintain a smooth and consistent experience for all users,” OpenAI says on its rate limit explanation page.

Along with the legions of others getting in on the trend, X and Tesla CEO Elon Musk shared an image mimicking King Mufasa from Disney’s The Lion King holding up a Shiba Inu. 

White House AI and crypto czar David Sacks also joined in, using the Studio Ghibli-art style on an image of himself at an event.

Meanwhile, Bloomberg reported on March 26 that OpenAI expects to more than triple its revenue this year to $12.7 billion, citing a person familiar with the matter.

Altman said on Feb. 12 his firm wants to ship GPT-4.5 and GPT-5 in the coming weeks or months.
