Google DeepMind's Gemini 3 Achieves Human-Level Reasoning on Math Olympiad Problems

Google DeepMind has announced that Gemini 3 achieved a historic milestone — gold-medal performance on the International Mathematical Olympiad (IMO), solving all six problems correctly and scoring 42 out of 42 points.

The IMO is considered the world's most prestigious mathematics competition for pre-university students. Gemini 3 completed the exam in under 30 minutes, compared to the 4.5 hours allotted to human participants. The system tackled problems spanning number theory, algebra, combinatorics, and geometry. The breakthrough comes from Gemini 3's new Chain-of-Thought Reinforcement Learning architecture. Unlike previous models that generated answers directly, Gemini 3 learns mathematical reasoning through an iterative process of generating multiple solution paths, evaluating each step, and self-correcting when it detects logical errors.

"Solving an IMO problem requires not just mathematical knowledge, but creativity and intuition — qualities we thought were uniquely human. Gemini 3 has shown that AI can develop genuine mathematical creativity."

— Sir Timothy Gowers, Fields Medalist and IMO Gold Medalist

Gemini 3 demonstrated particularly impressive performance on geometry problems, using a novel approach that combines symbolic reasoning with spatial visualization — an area where previous AI systems struggled. The system was able to construct auxiliary lines and visualize geometric relationships that even expert mathematicians described as elegant. The practical implications extend far beyond mathematics competitions. DeepMind has already applied Gemini 3's reasoning capabilities to drug discovery, where it identified three novel protein structures for antibiotic development, and to materials science, where it discovered a new room-temperature superconductor candidate. Google has announced that Gemini 3's mathematical reasoning capabilities will be integrated into Google Search, Google Workspace, and Google Cloud AI services starting next month. The company is also releasing a specialized Gemini 3 Math API for educational institutions and research organizations.
