I think that could be likely. I just asked 4o "When is Cheryl's birthday?" without any other context and was given this reply
Cheryl's birthday puzzle is a logic problem where Albert and Bernard are trying to figure out Cheryl's birthday based on certain clues.
Cheryl provides them with ten possible dates: May 15, May 16, May 19, June 17, June 18, July 14, July 16, August 14, August 15, and August 17.
Here’s the reasoning:
1. Albert knows the month and Bernard knows the day.
2. Albert says he knows Cheryl’s birthday, meaning May and June can be eliminated because they contain unique days (May 19 and June 18). If Albert had been told May or June, he wouldn’t know for sure.
3. Bernard, knowing this, says he now knows Cheryl’s birthday. This eliminates the remaining dates with unique days (July 14 and August 14).
4. Albert then confirms that he also knows the birthday, meaning Cheryl’s birthday must be in July or August, but on a date with no unique days left: July 16, August 15, or August 17.

Thus, Cheryl's birthday is *July 16*.
