Ethan Mollick / @emollick: Reasoning models (apparently without tool use) scored #1 (OpenAI) & tied for #2 (Google) in the International Collegiate Programming Contest Its been one year since reasoners were first announced, it is genuinely surprising how good they have gotten at hard problems, so quickly [image] Yes, we have reached a turning point. OpenAI achieved a perfect score at the ICPC World Final 2025 -- the most important university programming competition -- completing 12 out of 12 tasks in 5 hours, outperforming every human team. The AI team, which was not allowed to participate in the competition, was able to solve all problems in just 5 hours. They used GPT-5 and an experimental reasoning model. -AI beats elite students in complex algorithmic thinking for the first time -No special training: GPT-5 + reasoning model, universally applicable -Signal: AI is not just a tool, but surpasses human expertise
