> But as always, the methodology is buried: how many open problems were tried until they found a success?
Not only that, but they have like 500 world-leading experts in mathematics and IMO alumni, so how do we know one of the agents wasn't hardcoded to return a proof that the mathematicians had found?
I'm a mathematician/graph theorist, and I've tried ChatGPT 5.3, 5.4, 5.5, and now 5.6 on a bunch of simple-ish open problems, and I've never gotten a solution.
There's really no good proof system mature enough to do advanced graph theory. The leading library in Lean is Graphlib, and it's really not ready for research level theorems.
