"I talked to IMO Secretary General Ria van Huffel at the IMO 2025 closing party about the OpenAI announcement. While I can't speak for the Board or the IMO (and didn't get a chance to talk about this with IMO President Gregor Dolinar, and I doubt the Board are readily in a position to meet for the next few days while traveling home), Ria was happy for me to say that it was the general sense of the Jury and Coordinators at IMO 2025 that it's rude and inappropriate for AI developers to make announcements about their IMO performances too close to the IMO (such as before the closing party, in this case; the general coordinator view is that such announcements should wait at least a week after the closing ceremony), when the focus should be on the achievements of the actual human IMO contestants and reports from AIs serve to distract from that.
I don't think OpenAI was one of the AI companies that agreed to cooperate with the IMO on testing their models and don't think any of the 91 coordinators on the Sunshine Coast were involved in assessing their scripts."
