SWE-bench Verified → FrontierCode 1.1 Main
FrontierCode 1.1 Main is estimated from SWE-bench Verified with a offset logistic curve fitted on 6 models measured on both: y = 0.0000 + (0.5456 − 0.0000) / (1 + exp(−24.83·(x − 0.8064))), R² = 0.99, cross-validated error 2.7 pp. It is used for 73 estimates.
