Best computer-use agent finishes 20.6% of long-horizon tasks on OSWorld 2.0.

After GUI agents climbed from 12% to roughly 85% on the original OSWorld, the new 2.0 benchmark where the median task takes a human about 1.6 hours drops the best frontier system to 20.6%. This is the caution I keep repeating: a slick two-minute demo does not extrapolate to a two-hour workflow. The saturation of old benchmarks hid how far we are from reliable multi-hour autonomy.
