Current frontier AI agents remain far from reliable at long-horizon, multi-program computer-use tasks, with the best-performing setup reaching only 20.6% binary accuracy on OSWORLD 2.0, though rapid improvement is likely given how quickly scores rose on OSWORLD 1.0.

OSWorld 2.0, a benchmark of multi-hour, multi-program computer-use tasks, shows even Claude Opus 4.8 with maximum thinking only reaches 20.6% binary accuracy, though the field expects a rapid ramp similar to OSWORLD 1.0's rise from ~30% to ~75%. ✦ AI generated

Our experiments show that current agents remain far from reliable computer use: the strongest setting, Claude Opus 4.8 with maximum thinking and batched tool calls, reaches only 20.6% binary accuracy and 54.8% partial-score accuracy," they write.
