๐ Weโre proud to have held our first live math contest on Repovive, with nearly 200 participants. Five GPT-6 agents evaluated the submitted proofs, and their assessments were combined into a single verdict: Accepted or Rejected, with no partial credit.
๐ก We wanted to bring the live contest experience of competitive programming to mathematics. It was exciting to see people try it, and weโve received encouraging feedback on both the problems and the judging system.
๐ Participants who solved each problem:
A: 143 ยท B: 97 ยท C: 60 ยท D: 16 ยท E: 5
๐ฅ You can watch Alexander Golovanov and Um_nik tackle the contest:

After our first math contest, we graded 534 borderline submissions to create a gold standard. Then, we ran some experiments on how to improve it.
These accuracies are for this curated set of suspicious submissions. Overall accuracy is currently above 95%.
You can view the plot or read the full study here: https://x.com/ShayanCJahan/status/2106143879200440800
Let us know if you have a background in IOI/IMO/ICPC and you're interested in this kind of work.

Suppose someone writes i instead of n at one point in their proof. Itโs clearly a slip, but it makes the logic incorrect as written.
Do you think the judge should accept it or reject it?

OpenAI (and frontier labs) have served (and will serve) mathematics more than all the mathematics researchers in history combined.
