The title is misleading. The only thing they seem to have done was add a $100 plan identical to Claude's, which gives 5x usage of ChatGPT Plus. There is still a $200 plan that gives 20x usage.
Notably, up until now Pro had 6x usage of Plus. So the title is only slightly misleading.
On the other hand, the benchmark of Plus usage seems to be to be all over the place, so it’s difficult to say now how does the usage compare to the old Pro.
You’re right. I missed the “From $100”. Edited title.
Oh. Yikes.
That is not the "only" thing: You get access to GPT-5.4 pro.
