I just asked Google AI if a certain video game has a new game++ mode. That means you've played it through twice and you're going to play it through a third time.
Google's answer to me was "yes it does have a new game + (note the single plus) which some games call new game ++"
No.
Zero video games would call the third playthrough a single plus.
That's ridiculous. Large language models are ridiculous. And they feed you this information confidently.
