I noticed this a few times I tried using ai to solve a wordle I was about to give up on. It isn't just worthless, it like can not guess a 5 letter word based on a few rules like "second letter not a, d or g; first letter l, last letter w; word is not " lower"
Its not that it can't solve it, it can't even guess slightly correct. I think ai language isn't as connected to "spelling" as we think, I've heard of people using ai to translate instructions to Mandarin and then feeding the Mandarin query in because Mandarin is more "meaning dense" therefore uses less tokens and gets better answers
