Column guide

No.
Display order only. Sorting changes this number; it is not a published capability rank.
Model
The evaluated model name and its provider icon. A dash in a score column means no published score is available here, not a zero.
Score
Tests completing practical tasks in a terminal environment, such as coding and system operations. Versions use different task sets and should be compared separately. Evaluation methodology ↗

Vals.ai
Costs and times are reported by Vals for this benchmark, not universal model prices or latency. CUA-bench estimated API cost covers evaluation usage and is a lower-bound estimate, not cost per task; time per action is an average, not a median. An asterisk marks launch-day prompt-cache behavior that increased cache-write costs. Missing values are unpublished, not zero.
