Benchmarks: WebArena and OSWorld
WebArena tests web-agent capability across four self-hosted apps. OSWorld tests desktop-agent capability across Ubuntu, Windows, macOS. At release (2023–2024) both showed a big gap between best-in-class agents and humans. The gap is narrowing; the failure modes haven't changed.

It is part of the curriculum and will get the same treatment as Phase 1 — a visual cover, hands-on labs, derivations with numeric checks and a quiz. Until then, the original lesson is the best place to read it:
Part of Phase 14 — Agent Engineering. Use the previous / next cards below to keep browsing the phase.
