Two Chinese tech companies, Huawei and Xiaohongshu, said their AI models each achieved 100% on the questions given to human hopefuls at this month's International Mathematical Olympiad (IMO).
They were the first AI labs to announce their scores, but others from around the world may follow suit in the coming days.
"We are delighted with this result, because achieving a perfect score at the IMO is extremely challenging," Xiaohongshu said in a statement this week.
"Previously, no large language model had ever achieved a perfect score under the IMO's official judging process," the firm added, referring to the tech that underpins AI tools like chatbots.
In 2025, models made by the likes of Google and OpenAI reached gold-level scores for the first time -- but could not match the abilities of five human contestants who got 100%.
