Leaderboards

One board per question

No single ranking answers every question. Pick the measurement that matches the work you are actually doing — a model that tops GPQA may be nowhere near the top on long-context retrieval.

Headline

The composite indices

Aggregate scores. Useful for a shortlist, misleading as a final answer.

Intelligence Index

Composite of ten reasoning, knowledge, coding and agentic evaluations.

Arena Elo

Dot position on a 1,350–1,500 scale

1,3501,500

Head-to-head generation quality, judged pairwise. Elo has no meaningful zero, so bars from a zero baseline would flatten every gap.

Individual evaluations

The measurements underneath

Each of these is a real test with its own failure modes. A model absent from a board was not run on it — that is not the same as scoring zero.
