Cracking a 6-Month Grad School Problem: GPT-5.6 Pro Proves Complex Math Inequality

thomasahle · x · 2026-07-30

A user shared a surprising test result on social media: GPT-5.6 Pro successfully proved a mathematical inequality that they had struggled with for over six months during graduate school.

What's fascinating is that the model utilized the Schwarzian derivative—a technique Fields Medallist Bill Thurston once brilliantly explained on MathOverflow. This demonstrates the profound potential of current frontier AI models in handling highly abstract mathematical reasoning.
