You keep "upgrading" Chat GPT and releasing later versions, but it keeps making the same damned mistakes. Mistakes that it can rectify, because when I explicitly tell it "remove all the em dashes from the text," it does so without any problem whatsoever.

What's the point of asking it to remember something, if it's just going to ignore those instructions because "iT'S MyDeFaUlT BeHaViOr"

Unless you are an Open AI developer, there is no point in posting in here in an attempt to convince me this is somehow my fault. It isn't and I'm not going to argue about it.

I have a plus account and am using GPT-5 Instant

Still happening. fyi

Use "Thinking". It's THAT simple. (as I've said a few weeks ago)

I promise it'll immediately start following the instructions.

Tho, I am confused as to why you do not have access to GPT 5 Thinking. I am a Plus user, too.

"Unless you are an Open AI developer, there is no point in posting in here in an attempt to convince me this is somehow my fault. It isn't and I'm not going to argue about it."

But, like... it IS your "fault".. you should be using Thinking mode. Literally no "OpenAi Developer" is going to reply 😂

You want a fix? There it is. So either take your head out of your ahh and accept the help, or deal with it. But otherwise, there's no point making bug reports..
