Today, we at @OpenAI achieved a milestone that many considered years away: gold medal-level performance on the 2025 IMO with a general reasoning LLM—under the same time limits as humans, without tools. As remarkable as that sounds, it’s even more significant than the headline 🧵

1/N I’m excited to share that our latest @OpenAI experimental reasoning LLM has achieved a longstanding grand challenge in AI: gold medal-level performance on the world’s most prestigious math competition—the International Math Olympiad (IMO).

Καταδικάζουμε με τον πιο απόλυτο τρόπο το έγκλημα γενοκτονίας που συντελείται στη Γάζα και καλούμε την Κυβέρνηση να μιλήσει καθαρά στο φως, όχι ψελλίζοντας και με υπονοούμενα. Η κ Μπακογιάννη έκανε μια δήλωση για τη Γάζα που την τιμά, ωστόσο αυτό δεν καλύπτει την κυβέρνηση που…

At last, the international community is beginning to stand up to Israel’s operation to obliterate Palestine.

My joint statement with @Keir_Starmer and @EmmanuelMacron on the situation in Gaza and the West Bank: “We strongly oppose the expansion of Israel’s military operations in Gaza. The level of human suffering in Gaza is intolerable. Yesterday’s announcement that Israel will allow…



Romania’s new president (according to preliminary results) has a PhD in math and is a two times IMO world medalist with perfect score both times

Today, I cast my vote in Romania’s presidential elections. This time, something feels different. Remarkably different. I’m choosing a candidate who’s not the typical politician. In fact, he’s the kind of person you’d expect to see leading a world-class research lab, not a…

Current anti-refugee and migrant policies are robbing us of future Pedro Pascals.

Pedro Pascal at #Cannes: "I want people to be safe and protected. I want to live on the right side of history. I am an immigrant. My parents are refugees from Chile. We fled a dictatorship and I was privileged enough to grow up in the United States after asylum in Denmark. I…

1/19 I wrote recently a new paper that I’m very excited about, so I would like to explain what it is about. It is joint with Y. Lamzouri and J. D. Lichtman, and it concerns a question of Erdös from back in the day when he worked on primitive sets. arxiv.org/abs/2502.09539
