1/N I’m excited to share that our latest
@OpenAIexperimental reasoning LLM has achieved a longstanding grand challenge in AI: gold medal-level performance on the world’s most prestigious math competition—the International Math Olympiad (IMO).
Gold medal-level performance on the 2025 International Math Olympiad from our latest experimental reasoning LLM. Model operated in natural language (i.e. outputs natural language proofs) under the same rules as humans (e.g. 4.5 hours per session, no tools). Amazing milestone!
