Benchmarks are how you separate marketing claims from measured reality. Instead of trusting vendor-reported numbers, benchmarks run the same tasks against every system under a shared methodology and publish the results. For AI product builders picking an agentic extraction or search stack, a trustworthy benchmark is the single best input to the build-vs-buy decision – and a fast way to spot when a category is still too immature to rely on.

The most-cited computer-use benchmark – the one Anthropic, OpenAI, and Google quote when announcing agent capabilities. Tasks span Chrome, VS Code, Thunderbird, LibreOffice, GIMP, file managers, and OS-level workflows like file format conversions and calendar setup. Each task ships with an executable evaluation script, so scoring is deterministic.
Still hard for frontier models – Claude Sonnet 4.5 scored 61.4% in mid-2025, and a year later top systems are still well under 80% on the harder splits. For AI products that need to span apps (not just web pages), OSWorld is the right benchmark to test against. Browser-only agents should stick to WebArena, Mind2Web, or ClawBench.
