I was holding out hope for Q*, which OAI talked about with hushed tones to make it seem revolutionary and maybe even dangerous, but that ended up being o1. o1 is neat, but its far from a breakthrough. It's just recycling the same engine behind GPT-4 and making it talk to itself before spitting out its response to your prompt. I'm quite sure they've hit a ceiling and are now using smoke-and-mirrors techniques to keep the hype and perceived pace-of-progress up.
