SCORING METHODOLOGY
CALIBRATED. Pro variant of GPT-5.5; same base model, longer reasoning. Score deltas vs GPT-5.5 base: Reasoning +1, Math +1, Science +1, Bulk Apperception +1, Tenacity +1, Self-Correction +1, Speed -4 (longer thinking), Cost Efficiency -2 ($30/$180 per M). Hallucination rate inherited from base — Pro reasoning does not reduce AA-Omniscience hallucination. Reserved for the hardest 5% of real work where quality justifies 6x cost.
