Calibration · https://benchgap.net/calibration/1476 · data retrieved 2026-10-29

DeepSWE is estimated from SWE-bench Verified with a Hill curve fitted on 9 models measured on both: y = 0.0000 + (1.1142 − 0.0000)·x^6.00 / (0.85573^6.00 + x^6.00), R² = 0.54, cross-validated error 12.7 pp. It is used for 33 estimates.
