# Vals LiveCodeBench → VulcanBench v3

Calibration · https://benchgap.net/calibration/1584 · data retrieved 2026-10-29

VulcanBench v3 is estimated from Vals LiveCodeBench with a offset logistic curve fitted on 12 models measured on both: y = 0.7613 + (1.2000 − 0.7613) / (1 + exp(−10.44·(x − 1.0015))), R² = 0.31, cross-validated error 5.6 pp. It is used for 38 estimates.
