Over the past month or so, OpenAI’s generative AI chatbot ChatGPT has gone viral for its ability to not only answer simple questions, but write essays or debug code, all in humanlike text.

Generative AI analyzes huge amounts of data and trains models that can generate new things. Feed a generative-AI program millions of pieces of art, and it learns how to produce art, like OpenAI’s other viral sensation DALL-E.

It was only a matter of time before Ryan Reynolds used it for an ad. And today, he dropped one for Mint Mobile.

In the new spot, Reynolds says he asked ChatGPT to write a commercial for Mint Mobile in his voice, with a checklist of using a joke, a curse word, and letting people know that Mint’s holiday promo is still going. The result, in Reynolds’s IRL words, is “eerie” and “mildly terrifying.”

Rest assured, Mint Mobile isn’t the only brand eyeing the technology for its advertising potential. On Monday, Semafor reported that Microsoft is in talks to invest $10 billion in OpenAI, putting its valuation at $29 billion.
