Summary

A new AI IQ leaderboard by Ryan Shea claims GPT-5.5 scores 136 IQ, breaking a ceiling that Maxim Lott's established leaderboard has held at 130 since October 2025. The post tracks AI IQ rising from ~80 in May 2024 to 130 by October 2025 — a rapid 17-month climb — then apparently plateauing until this new benchmark claims to resolve the stagnation with a recalibrated methodology. The scoring difference between the two leaderboards is not yet independently documented.
