I wonder what changed with the models that created regression?

Not sure but with each release it feels like they’re just wiping the dirt around and not actually cleaning.

There is some speculation that GPT-5 uses a router to decide which expert model to deploy (e.g. to mini vs o/thinking models). So the router might decide that the query can be solved by a cheaper model and this model gives worse results.
