According to CoinMeta, Cua in collaboration with Scale AI launched a computer operation evaluation. During the tests, the complete pass rate of Cua and driver reached 58%, while for browser-use it was only 3%. The advantage of Cua lies in its ability to directly operate on background windows; ordinary computer operation tools usually require switching the target window to the foreground. The tests showed that Cua successfully completed 32 out of 40 tasks, but in 31 of those cases it interfered with the user, and ultimately only 1 task was completely passed. All tools used Claude Sonnet version 5.5, and the tests covered tasks such as browsing, email, calendar, and spreadsheets.
