AI agents attempting OSWorld's real-world computer tasks across Ubuntu, Windows and macOS — file operations, multi-app workflows — historically topped out at just 1% to 12% success. Stanford's 2026 AI Index reports the best model, Claude Opus 4.5, now reaches 66.3% accuracy, within 6 percentage points of the 72.35% human baseline 66.3% accuracy on OSWorld's real-computer-task benchmark

- Frontier AI models are catching up fast to benchmarks meant to resist them. A year ago they scored under 10% on Humanity's Last Exam, a 2,700-question test designed to be hard for AI and favorable to human experts. Now accuracy has reached 38.3% on Humanity's Last Exam, up from under 10% a year earlier
- Epoch AI's Capabilities Index scores frontier models on one aggregate scale, and fits a break in the trend at April 2024, when reasoning models and reinforcement learning took over frontier training. Before the break the frontier gained 8.3 index points a year; after it, 15.5 points a year, 1.85 times as fast
- Epoch AI tested three commercial AI detectors — Pangram, GPTZero, Originality.ai — pinned to their June 2026 versions. Against plain machine-generated text they catch nearly everything, but shown five samples of a specific author's writing and told to imitate the style, AI detectors missed 13% of style-imitated AI passages, versus under 1% of plain AI text
