GPT 5.6 Pro solved all 6 problems from IMO 2026 on the first attempt without any human help or steering. International Mathematical Olympiad (IMO) is the biggest global academic competition in the world. The problems are considered incredibly hard, usually a performance at this level is only accomplished by < 5 contestants from the whole world. It’s not surprising given the recent research breakthroughs, but still worth noting! We are former IMO medallists not affiliated with OpenAI, just put together a report and assessment of its work here. We’re also working on a comparison report between different LLMs and harness augmented versions that will come later.
