Ranked by how many model versions have been scored — a proxy for which evaluations the field actually treats as load-bearing.
Epoch Capabilities Index leads with 462, ahead of MMLU (217) and Terminal-Bench (203).
Benchmarks saturate: a test that separated models two years ago is often solved by everything today, which is why the set keeps growing and why an aggregate index exists at all. The Epoch Capabilities Index combines across them so progress stays visible after individual tests top out.
