I think we have reached a form of weak AGI in the domain of mathematics. The models can help formalize major projects, they deliver technical expertise in basically any area of mathematics, and more and more mathematicians use models for exploration, exploitation, and even ideation. I am preparing a longer post about this. From my own projects in algebra, I can see that the speedup and jump in quality are unprecedented. To be honest, most mathematical questions are intractable for AI systems, but they are hopeless for humans, too. A surprising number of problems described in the literature can be cracked with the right auto-research skills and clever harnesses (and a ton of tokens) within days. Things are changing way too fast to comprehend every change. But I do see very young researchers, including PhD students, starting completely new, crazy projects exploring the interactions between models and mathematics. So there is hope that these people will lead the frontier in a few years and we won't end up with a frontier devoid of human mathematicians.
