Meta AI Sweeps Five STEM Olympiads With Perfect Scores and Zero Tools
Meta's AI models swept five STEM Olympiads — including perfect scores in physics — with no tools, no calculators, and no search allowed.
- Meta AI swept five STEM Olympiads, earning perfect scores in physics (APhO, IPhO) and gold medals in math and chemistry.
- All results were achieved with zero tool use — no search, no code, no calculator — testing pure model reasoning.
- The APhO perfect score of 30/30 cleared the gold medal threshold of 21-23 by a wide margin.
- Meta joins Huawei, Xiaohongshu, Google, and OpenAI in a fast-moving race to Olympiad-level AI reasoning.
- The results signal that LLMs can now handle genuinely novel, multi-step reasoning — not just pattern-matched recall.
- IMO is now considered a saturated benchmark; the field needs new, harder evaluation standards.
Meta AI announced that its models competed in five major STEM Olympiad competitions and won gold across all of them. The results: perfect scores on the theory exams of both the Asian Physics Olympiad (APhO) and the International Physics Olympiad (IPhO), a gold medal at the International Mathematical Olympiad (IMO), and gold-medal-level performance at the International Chemistry Olympiad (IChO) and the Romanian Masters of Mathematics (RMM). Every result was achieved without tool use: no search, no code execution, no calculator.
What these scores actually mean
These are proof-based competitions, not multiple-choice tests. The IMO, held annually since 1959, brings together top young mathematicians from over 100 countries to solve problems that demand creativity and logical reasoning under time pressure. Physics Olympiads require contestants to derive solutions from first principles. Both formats are designed to resist pattern-matching.
Meta's scores don't just clear the gold threshold, they exceed it by a wide margin. On the APhO theory exam, the model scored a perfect 30/30. Gold typically requires 21 to 23 out of 30. The model had to produce full written proofs and derivations using only its internal reasoning, the same conditions human contestants face.
