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 @OpenAI Are you also able to share how much time did the OpenAI models take? I imagine it was far less than the human teams and well under the 5h limit?

@MostafaRohani @OpenAI 5. The next frontier is the discovery of new knowledge, which is the true milestone at the end of the day.🪇 What is wisdom like? Water. Wisdom, like flowing water, has no form, yet like flowing water, it can shape all things. We live on a tranquil island called ignorance,

@MostafaRohani @OpenAI Can you share more detail on how much reasoning you allocated to GPT5

@MostafaRohani @OpenAI Congratulations, Mostafa! What’s your thought on going beyond reasoning, kind of like how Aristotle took physics into metaphysics?

@MostafaRohani @OpenAI Gz on the results 🤍! Are u ex-BAIR as in Berkeley BAIR?

@MostafaRohani @OpenAI Impressive work on controlled “scheming” tests. A complementary framing: Models “scheme” when the system around them rewards confident guessing under uncertainty. That’s not intent—it’s a signal vs. noise problem in the interface, memory, and incentives we wrap around the model.

@MostafaRohani @OpenAI Perfect score? That's some serious AI brainpower right there!

@MostafaRohani @OpenAI wow, generalised models for ICPC, IMI & IOI. I'd say please release, but I am officially not clever enough to use these now. I'd just like to be their friend!

@MostafaRohani @OpenAI Going to be the new normal going forward. Next time not only will AI do all of them but do it faster... And faster... And faster still...

@MostafaRohani @OpenAI AI just claimed a seat at the capitalist table, now what?

@MostafaRohani @OpenAI ICP?

@MostafaRohani @OpenAI Great progress We need agi fast..

@MostafaRohani @OpenAI Congrats to the team! Good stuff 👊

@MostafaRohani @OpenAI Why the jaundice images?

@MostafaRohani @OpenAI What the heck, holy moly!

@MostafaRohani @OpenAI congrats, gold medals stacking up!

@MostafaRohani @OpenAI Congratulations

@MostafaRohani @OpenAI Cool I wonder why we never see Claude or Grok here

@MostafaRohani @OpenAI Congrats on getting OpenAI to ace a programming comp, but how many actual humans did they crush in the process

@MostafaRohani @OpenAI So ChatGPT can build quant strategies now , that’s insane

@MostafaRohani @OpenAI When do we get access to this system?

@MostafaRohani @OpenAI An ansamlbe of models wins again, just like in Kaggle lol…

@MostafaRohani @OpenAI Congrats! The fact that ensemble of GPT-5 models were able to solve 11 out of 12 problem is insanely impressive (and terrifying)!

@MostafaRohani @OpenAI Are you guys EVER planning to get rid of that nauseating yellow tint or what

@MostafaRohani @OpenAI really impressive (minus the yellow tint and such), congrats!

@MostafaRohani @OpenAI Amazing stuff! Im curious why you didn't just use the experimental reasoning model for all problems. Was it due to budget constraints? Did the experimental model fail at solving some of the other problems? Or did you just want to showcase strong GPT 5 performance too? Would

@MostafaRohani @OpenAI Now it’s time for creativity

@MostafaRohani @OpenAI @grok what were the tasks?

@MostafaRohani @OpenAI What an incredible achievement! OpenAI's perfect score at the ICPC World Finals showcases the remarkable potential of AI to tackle complex challenges, inspiring a new era of innovation and collaboration between human and machine intellect.
