I've read plenty of criticism about ChatGPT 5, but as a Plus user I'm surprised nobody has brought this up:

Speed.

ChatGPT 5 Thinking is So. Much. Slower. than o4-mini and o4-mini-high. Like between 5 and 10 times slower. Am I the only one experiencing this? I understand they were "mini" models, but those were the current-gen thinking models available to Pro. Is GPT 5 Thinking supposed to be beefier and more effective? Because the output feels no better.

I think it's more appropriate to compare GPT 5 Thinking to o3. You will find that the response times are actually quite similar (at least in my experience over hundreds of identical prompts with each model).

Yeah, I always use mistral for fast answers.
