OpenAI says its experimental language model has solved International Mathematical Olympiad (IMO) problems at a gold medal level\u2014a possible breakthrough for AI with general reasoning skills. The results have not yet been independently confirmed.<\/p>\n

According to OpenAI researchers Alexander Wei<\/a> and Noam Brown<\/a>, the model tackled the IMO 2025 competition, solving the first five of the six official problems and earning 35 out of a possible 42 points.<\/p>\n

The IMO is considered the most difficult math competition for high school students, requiring creativity and rigorous logical reasoning. Wei claims this is the first AI model that can “craft intricate, watertight arguments at the level of human mathematicians.”<\/p>\n

The model generated its solutions under standard competition conditions: two 4.5-hour sessions, no outside help, all answers written in natural language, and no tool use. Former IMO medalists graded the responses anonymously. The full solutions are available on GitHub<\/a>.<\/p>\n

Still room to scale<\/p>\n

Unlike DeepMind’s AlphaGeometry<\/a>, which is built specifically for math, OpenAI’s model is a general-purpose reasoning language model. “We reach this capability level not via narrow, task-specific methodology, but by breaking new ground in general-purpose reinforcement learning and test-time compute scaling,” Wei explains.<\/p>\n

Brown confirms that the model relies on “new experimental general-purpose techniques” and scales its compute at test time<\/a>, though he doesn’t share the technical details.<\/p>\n

“o1 thought for seconds. Deep Research for minutes. This one thinks for hours,” Brown notes<\/a>, pointing out that the new model is more efficient and still has scaling potential. He argues that even a small advantage over human performance can be enough to drive major scientific progress.<\/p>\n

Wei says OpenAI has no plans to release this model or a similar one in the coming months, stressing that it’s strictly a research project. He also clarified that while GPT-5 is planned “soon”<\/a>, it is unrelated to the IMO model, which was developed by a small team led by Wei.<\/p>\n

Brown points out<\/a> that the technology could eventually become a product, and with progress moving so quickly, future versions may be even more advanced. He adds that the results surprised even people inside OpenAI, calling it “a milestone that many considered years away.”<\/p>\n

Current models are far behind<\/p>\n

The timing of OpenAI’s announcement seems intentional, coming just after current AI models delivered disappointing results at the same competition.<\/p>\n

A recent evaluation by the MathArena.ai<\/a> platform tested several leading models-including Gemini 2.5 Pro, Grok-4, DeepSeek-R1, and even OpenAI’s own o3 and o4-mini-on the IMO 2025 tasks. None of them managed to score the 19 points needed for a bronze medal. Gemini 2.5 Pro came out on top, but with only 13 out of 42 points, while the others performed even worse.<\/p>\n

Even with extensive testing, which included a best-of-32 selection process and evaluations by IMO experts, the models showed serious flaws. The results were filled with logical errors, incomplete arguments, and even made-up theorems.<\/p>\n

Viewed in this context, OpenAI’s announcement looks like a direct response to the limitations exposed by the MathArena test. While the achievement is significant, its true value will depend on whether the results can be independently reproduced and applied to real scientific problems.<\/p>\n","protected":false},"excerpt":{"rendered":"Summary OpenAI says its experimental language model has solved International Mathematical Olympiad (IMO) problems at a gold medal…\n","protected":false},"author":2,"featured_media":9742,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[20],"tags":[554,6158,6159,733,4308,874,86,56,54,55],"class_list":["post-9741","post","type-post","status-publish","format-standard","has-post-thumbnail","category-artificial-intelligence","tag-ai","tag-ai-and-math","tag-ai-research","tag-artificial-intelligence","tag-artificialintelligence","tag-openai","tag-technology","tag-uk","tag-united-kingdom","tag-unitedkingdom"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/9741","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=9741"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/9741\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/9742"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=9741"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=9741"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=9741"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
