⚡️Math Olympiad gold medalist explains OpenAI and Google DeepMind IMO Gold Performances

Introduction and Background 00:03

  • Jasper Jang, co-founder of Hyperbolic, describes how frustration over limited GPU access led to building Hyperbolic, an on-demand AI cloud for developers.
  • The conversation shifts from Hyperbolic to Jasper's experience with Math Olympiads and recent AI achievements.

AI Achievements in Math Olympiads 01:17

  • Both DeepMind and OpenAI have recently claimed gold medal-level performance at the International Mathematical Olympiad (IMO).
  • OpenAI's announcement came via social media, while DeepMind required additional verification from the competition organizers before confirming their results.
  • OpenAI did not officially participate; instead, they used IMO problems and had their solutions reviewed by former IMO medalists.
  • DeepMind's claim was officially verified by the competition.

IMO Background and AI Approaches 04:45

  • IMO is a prestigious high school mathematics competition focused on combinatorics, number theory, geometry, and algebra, emphasizing problem solving over advanced knowledge.
  • Achieving gold medal level in IMO is considered a major milestone for AI, indicating advanced reasoning abilities.
  • Last year, DeepMind's approach with formal verification systems like Lean achieved a silver medal; this year, both Google and OpenAI succeeded with language model (LM) reasoning, moving away from formal proof languages.
  • Previous AI solutions could take up to 60 hours for some problems, far exceeding the human time limit of 4.5 hours; recent advances have dramatically reduced solution time.

Analysis of IMO Problems and AI Performance 07:32

  • Different IMO problems test varied skills: problem one often focuses on combinatorial geometry and case analysis, which AI models managed to solve using reduction strategies.
  • AI solutions sometimes approach problems differently from humans but can still produce valid answers.
  • While IMO tests logical problem solving, it does not evaluate deeper mathematical creativity or capability in advanced research.
  • The most difficult (sixth) problem usually remains unsolved by both AI and many humans, primarily requiring higher-level creativity and experimentation.
  • Past bench-marking shows AI struggles most with combinatorial creativity and constructing counterexamples.

Limitations of Current AI and Benchmark Improvements 15:00

  • Current benchmarks focus on competition problems and do not comprehensively evaluate true mathematical ability, such as conjecture formulation or advanced creativity.
  • Jasper is involved in a project to create a new, more holistic benchmark, breaking down mathematical expertise into categories: knowledge and understanding, problem solving and communication, learning/meta-skills, creativity, and intuition.
  • Collaboration between mathematicians and AI researchers is emphasized as key to developing effective measures and reward functions for creativity.

Lean, Natural Language, and Proof Verification 23:29

  • AI models can approach mathematical proofs either with natural language or formal systems like Lean.
  • Natural language outputs are easier to generate and interpret but harder to verify.
  • Formal systems like Lean offer clearer verification but currently lack large training datasets.
  • Both approaches are expected to advance, with parallel efforts in expanding Lean data and in improving language model capabilities.
  • There are ongoing projects, such as Kevin Buzzard's attempt to formalize the proof of Fermat's Last Theorem in Lean.

Breakthroughs and Scaling in AI Math Performance 27:21

  • There is speculation about the nature of the breakthroughs achieved by OpenAI and DeepMind, with mentions of larger-scale training, better data, and advances in multi-step reasoning (e.g., parallel idea exploration, improved reinforcement learning).
  • Significant performance gains, such as reducing solution time from 60 hours to under 4 hours, suggest more than just scaling—new ideas for efficiency and reasoning are likely involved.
  • Recent Gemini model tests showed that both curated and non-curated versions achieved high performance, strengthening confidence in results.

Future Directions and Milestones for AI in Mathematics 31:32

  • Current benchmarks are compared to exams; the real test for math-capable AI is making breakthroughs in genuine open problems.
  • The ultimate aspiration is for an AI to generate new mathematical theories or solve long-standing open problems, potentially winning a Fields Medal (the highest prize in mathematics).
  • The conversation closes with an invitation to further explore and solve IMO problems together.
