Artificial Analysis Intelligence Index → CritPt
CritPt is estimated from Artificial Analysis Intelligence Index with a Hill curve fitted on 186 models measured on both: y = 0.0000 + (0.4417 − 0.0000)·x^3.51 / (0.46132^3.51 + x^3.51), R² = 0.87, cross-validated error 3.7 pp. It is used for 2 estimates.
