AI at the Math Olympiad: A New Era of Mathematical Problem-Solving The IMO has long been the world’s toughest math competition for top students. Now, it's becoming a benchmark for AI reasoning too.👇

This year marked a milestone: AI models from Google DeepMind and OpenAI reached gold medal performance on IMO problems — the same level as top human contestants. A true leap in AI’s ability to reason through abstract math.

Timeline of Events: > Friday: News leaked about DeepMind's gold medal performance > Saturday 1am: OpenAI announced results ahead of official confirmation > Monday: DeepMind officially confirmed gold medal status with elegant solutions fully verified by IMO officials. Their solutions were more elegant & rigorously checked

Tech Shift from 2024 to 2025 Last year: AI models like AlphaGeometry needed domain translation (Lean, etc.) + 2–3 days compute. This year: Gemini & OpenAI’s models solved problems end-to-end in natural language, within the 4.5-hour IMO limit.

Style Differences OpenAI’s answers: > Logically sound, but messy > Lacked structure, overused terms like “forbidden” > 400+ lines for some problems > Not human-readable Gemini’s proofs: > Elegant and clear, IMO graders said they were “easy to follow” > Could pass as human-written

Problem 2 (Geometry) showed the gap: OpenAI used brute-force coordinate geometry → correct but clunky 442-line proof DeepMind’s Gemini used angle chasing & Sylvester’s theorem → concise, insightful solution that mirrored a skilled human.

Why Gemini Succeeded > Parallel thinking: Exploring multiple solution paths simultaneously > Novel reinforcement learning techniques enhancing multi-step reasoning > Access to carefully curated mathematics solutions and strategic hints

OpenAI’s approach? General-purpose RL + test-time compute scaling.

What This Means Solving IMO problems is impressive, but real math goes deeper: > Abstract reasoning > Concept creation > Research intuition We’re not there yet—but this is a real step forward.

To truly push AI math capabilities forward, we’ll need: > Granular reward functions > Specialized RL pipelines > Or maybe… a wildcard technique no one saw coming

As AI pushes into math, science, and research — the need for compute explodes. That’s why access to affordable, scalable GPU infrastructure is mission critical. Let’s make that future accessible to all.
