Record completeness
Claims
Notably, the strongest model, GPT-5.5, now reaches 98% on the 2026 USA Math Olympiad and 74% on research-level questions, showing that frontier models can now comfortably solve extremely challenging mathematical problems.
The new benchmarks and evaluation protocol remain free of training-data contamination and fairly measure genuine reasoning rather than memorization or benchmark-specific shortcuts.
MathArena is broadened into a maintained platform with new benchmarks for proofs, research questions, and formal verification, where GPT-5.5 scores 98% on 2026 USAMO and 74% on research-level tasks.
