# SWE-bench Pro → OpenHarmony Bench

Calibration · https://benchgap.net/calibration/1468 · data retrieved 2026-10-29

OpenHarmony Bench is estimated from SWE-bench Pro with a offset logistic curve fitted on 7 models measured on both: y = 0.5328 + (0.6090 − 0.5328) / (1 + exp(−200.00·(x − 0.6181))), R² = 0.50, cross-validated error 4.9 pp. It is used for 14 estimates.
