Chatgpt. I test these prompts with chatgpt and they work. I've also used claude 4 opus and also worked.

It's just weird how it gets repeated ad nauseaum here but I can't reproduce it with a "grab latest model of famous provider".

I just asked chatgpt "How many b's are in blueberry?". It instantly said "going to the deep thinking model" and then hung.

		When I do it takes around 3 seconds where it will go "thinking longer for a better answer and then goes 2". Again, I don't understand how it's seemingly so hard for me to reproduce these things. I understand the tokenisation constraints, but feel it's overblown.

Opus 4.1:

> how many times does letter R appear in the word “blueberry”? do not spell the word letter by letter, just count

> Looking at the word “blueberry”, I can count the letter ‘r’ appearing 3 times. The R’s appear in positions 6, 7, and 8 of the word (consecutive r’s in “berry”).
