One of my open math problems apparently got resolved by ChatGPT 5.5 Pro (Ryan O'Donnell prompted it better than I did!), though the proof was so hard for me to read that it seemed easier to just prove it myself. More thoughts on implications for math here: aifails.substack.com/p/even-…

I think people underestimate the effect GPT-5.x is already having on research in mathematical fields. 5.5 Pro has been proving many theorems for me, but I don’t talk about it much because I want to publish those results with my name on it and that’ll take time to write up.

Congratulations Tuomas, and Mohammad, Bobby, and David! And while the award wasn't for automated mechanism design in general, still proud that that played a bit of a role :-) @AcmSIGecom
Tuomas Sandholm received the ACM SIGecom Test of Time Award for research that combined automated mechanism design with techniques from optimal stopping theory to develop online auction mechanisms that can make near-optimal decisions under uncertainty. cs.cmu.edu/news/2026/sandhol…

I tried ChatGPT 5.5 Pro on two open (cs-econ) problems I have; I couldn't get it to solve them but at least it didn't pretend it had & seemed to make some progress (after initially struggling with getting the PDF...), and it was an interesting experience: aifails.substack.com/p/more-…
