# SWE-bench Pro → AA Coding Index

Calibration · https://benchgap.net/calibration/1456 · data retrieved 2026-10-29

AA Coding Index is estimated from SWE-bench Pro with a Hill curve fitted on 38 models measured on both: y = 0.2114 + (0.8676 − 0.2114)·x^6.00 / (0.53173^6.00 + x^6.00), R² = 0.72, cross-validated error 7.5 pp. It is used for 2 estimates.
