I’m one of the moderate fanboys and I love gpt5 and not having to switch models anymore, compared to before. So far, it’s pretty good about when to think longer and when to give quick answers.

That being said, I don’t use it for anything other than STEM concepts and coding tasks. I have no idea what the complainers use it for.

I did here that people though it had less “personality”. Funny, I did notice it got more concise in its answers. This was an improvement for me, but I’m using it as a tool, not a friend or therapists or something. To each their own.
