ARC-AGI-3 Human Baseline Now Means Median Not Outlier

ARC Prize didn’t just tweak a benchmark. The ARC-AGI-3 human baseline now uses a median human run per level instead of the second-best human, and it raised the per-level score cap from 100% to 115%. That sounds minor. It isn’t. The obvious reading is that ARC-AGI-3 got easier. The better reading is...
