Better evidence, fewer benchmarks.

Your preferences guide the search. Quality helps break close calls.

Coverage counts how many models have measured results — a test most models took beats a niche one.

Recency rewards recent test releases. An unknown release date gets a neutral score. A fresh scrape is not a fresh benchmark.

Headroom measures saturation and score spread. Tests that separate models beat tests everyone passes.

Objectivity favors verifiable outcomes over preferences and subjective judging.

Quality combines 25% coverage, 25% recency, 30% headroom, and 20% objectivity — plus a bonus for preferred benchmarks, minus a penalty for superseded versions. Objectivity is an assigned judgment score. This heuristic does not measure contamination or scientific validity.
