2/n We officially competed in the onsite AI track of the ICPC, with the same 5-hour time limit to solve all twelve problems, submitting to the ICPC World Finals Local Judge - judged identically and concurrently to the ICPC World Championship submissions. We received the problems

3/n We competed with an ensemble of general-purpose reasoning models; we did not train any model specifically for the ICPC. We had both GPT-5 and an experimental reasoning model generating solutions, and the experimental reasoning model selecting which solutions to submit. GPT-5

4/n This result is a great capstone to our streak of results showcasing the impressive pace of improvement of our reasoning systems. The same set of models also competed in the IMO and IOI, highlighting the generality of these systems.

5/n This is just the beginning, and I’m personally very excited about our research roadmap. The next frontier is the discovery of new knowledge, which is the true milestone at the end of the day.

6/n The competition itself was electric, a confluence of many of the smartest young minds in the world. Huge congrats to all of this year’s participants! Thanks to the ICPC committee for organizing such a great competition and for allowing us to compete. And kudos to the ICPC

7/n The city of Baku is beautiful, an ancient city at the crossroads of many historic civilizations. We really enjoyed exploring the city in our spare time. Here we are touristing at the Palace of the Shirvanshahs 😀

8/n Research is very much a team sport, and it was so much fun to work with @wyndwarrior, @robin_a_brown, and @bminaiev on prepping for the competition—and with @_lorenzkuhn, @clavera_i, @andresnds, and @ahelkky on competitive programming in general. I remember when I joined

@MostafaRohani How many GPT 5s are running simultaneousy?(another formulation of my question: for each question the experimental model chooses from several answers, but from how many answers does it choose?)
