Benchmark checker Agents and computer use

Is OSWorld-Verified still meaningful?

Status:Near ceiling Checked against the report, 5 November 2026

Verdict

No longer for the frontier. Agents have reached the human baseline.

Why near ceiling: Claude Sonnet 4.6 scored 72.1% in February 2026, against a human baseline of 72.36%.[1][1] Benchmark data bundle Epoch AI Primary

What “Near ceiling” means

Known problems

  • About 15% of its tasks need only a terminal, so it overstates screen skills.[2][2] What OSWorld tells us Epoch AI Primary
  • OSWorld-Verified fixed community-reported issues in July 2025. The last tagged OSWorld release dates from June 2024.[3][3] OSWorld README XLANG Lab Primary

What to look at instead

  • OSWorld 2.0 Status:Still useful Yes. Full-credit scores stay low, though partial credit tells a kinder story.
  • Remote Labor Index Status:Still useful Yes. It is one of the few tests where the best agent still fails most tasks.
