alt Hacker News> With LLMs being unable to count how many Bs are in blueberry, they clearly don't have any world model whatsoever.
Is this a real defect, or some historical thing?
I just asked GPT-5:
How many "B"s in "blueberry"?
There are 2 — the letter b appears twice in "blueberry".

It is not historical:

Perhaps they have a hot fix that special cases HN complaints?

It was discussed and reproduced on GPT-5 on HN couple of days ago: https://news.ycombinator.com/item?id=44832908
Sibling poster is probably mistakenly thinking of the strawberry issue from 2024 on older LLM models.

Shouldn't the correct answer be that there is not a "B" in "blueberry"?

It’s a historical thing that people still falsely claim is true, bizarrely without trying it on the latest models. As you found, leading LLMs don’t have a problem with it anymore.
