> and the routing engine was routing to smaller, specialized dumber models that cost less on inference?

That this was part of it was stated outright, except maybe that they "cost less" which was left for you to infer (sorry), in their launch announcement.

Paying for pro, and setting it to thinking all the time, I saw what seemed like significant improvements, but if your requests got (mis-)routed to one of the dumber models, it's not surprising if people were disappointed.

I think they made a big mistake in not clearly labelling the responses with which of the models responded to a given request, as it made people complain about GPT 5 in general, instead of complaining about the routing.
