ARC-AGI-2
The ARC-AGI-2 abstract-reasoning puzzle benchmark (semi-private set), the harder static successor to ARC-AGI-1.
What this benchmark measures
The ARC-AGI-2 abstract-reasoning puzzle benchmark (semi-private set), the harder static successor to ARC-AGI-1.
Rows on this page are sourced from public benchmark artifacts, leaderboard exports, or source-linked model reports. Each row keeps benchmark version, source model name, and available run details attached to the score.
The metric shown here is accuracy. It should be interpreted within ARC-AGI-2, not compared as part of a site-wide ranking.
What to be careful about
Public and semi-private splits differ; keep the reported effort/compute as run context.
Frequently asked
What is ARC-AGI-2?
The ARC-AGI-2 abstract-reasoning puzzle benchmark (semi-private set), the harder static successor to ARC-AGI-1. It is a reasoning benchmark measured by accuracy.
What does accuracy mean on ARC-AGI-2?
ARC-AGI-2 reports accuracy (%); higher is better. Scores are shown only within ARC-AGI-2 and are never averaged with other benchmarks.
What is the top reported ARC-AGI-2 score?
GPT-5.5 has the top reported score on ARC-AGI-2: 85% (accuracy).
Why do ARC-AGI-2 scores differ across runs?
Harness, scaffold, reasoning effort, and prompt setup change results, so two runs of the same model can differ. evals.report keeps each score with its run context so the differences stay visible.
Does evals.report rank models across benchmarks?
No. ARC-AGI-2 scores are shown within their own metric; evals.report never combines benchmarks into a composite ranking or a single "best model".
