That’s gone in 27. You can still ask ChatGPT by prefixing your request with “ask ChatGPT“ like you’ve been able to for the last two years or so.

But it will never prompt you anymore, because Siri AI can handle that stuff now when it couldn’t before.

Whether you think it’s better or not is up to you. I do. I also found the version of ChatGPT it used to be worse than the one in the app.
