I’ve seen papers that show they can do math. There was one recent-ish one HN that showed an understanding of addition. I’m not convinced myself. At least the open weight models don’t seem to grasp integers. Doing conversions are typically a flop as well. My doubt really comes from how abstract mathematics really is. It’s entirely its own kind of terse language and symbolism. Maybe if there was the kind of focus on it like coding there would be better results?
