ARC-AGI-1 → Artificial Analysis Intelligence Index
Artificial Analysis Intelligence Index is estimated from ARC-AGI-1 with a Hill curve fitted on 32 models measured on both: y = 0.1834 + (1.2000 − 0.1834)·x^6.00 / (1.11705^6.00 + x^6.00), R² = 0.63, cross-validated error 7.0 pp. It is used for 1 estimate.
