ChatGPT Just Got a Surprise Update, But OpenAI Can’t Explain How It’s Better

Perhaps Sam Altman’s strawberry photo was a secret message after all, because about a week after OpenAI’s CEO posted the photo to social media, the company confirmed that ChatGPT received a surprise update last week that it hadn’t told anyone about.

This was announced on social media by an official ChatGPT account, which revealed that “there is a new GPT-4o model in ChatGPT”, later adding that this is not a new model like a GPT-5 upgrade, but merely an improvement to the existing GPT-4o model.
