It's hard to say, super subjective. It's just wrong more often and sometimes it goes off in tangents wrt. what I asked. Also I might ask a question and it starts coding an entire React project. Every once in a while it will literally max out its response tokens because it can't stop writing code.
I see. I have a similar feeling; as if they made it to quickly force you to pay (quickly maxing out one conversation in my case). I'm quite cynical and paranoid in this regard and I try hard not to be ruled by those two... but I can't shake the feeling that they're right this time.
Just feels less "stable" or "tight" overall.
