What makes a good reasoning model?

Reasoning benchmarks test whether a model can solve multi-step problems requiring planning, logic and domain knowledge, not just pattern matching or retrieval.

  • GPQA (Diamond): questions written by PhD-level experts in biology, chemistry and physics, designed so that non-experts who search for the answer still fail.
  • AIME 2026: the American Invitational Math Exam, 2026 edition. 30 hard problems with integer answers. Its problems are recent, so they are less likely to be in training data.
  • AIME 2025: the same format, one year earlier. Used alongside 2026 for a more stable picture of math reasoning capability.

Each score links to its source on the benchmarks leaderboard; scores from independent evaluators (Vals AI, Artificial Analysis) and from developers' own announcements are both used, and developers' figures are often higher.
