It wasn't always like this. GPT in early 2023, hell late 2022, was incredible. I could have it fully stimulating a Unix terminal on acid for hours, it'd never break character. It's so insanely nerfed now.
It's insanely good every time they have a public release, then deteriorates significantly. There's plenty of evidence around this too - just compare the exact same prompt then and now. Not sure if this is a matter of cost or just playing whack a mole with unintended behaviorial bugs.
