Computer-use agent experience = capability × robustness × efficiency. As frontier models climb higher on CUA benchmarks, efficiency becomes increasingly attrative, as highlighted by the recent release of #Jev#. With many intermediate steps in everyday computer-use tasks being “local,” fast System-1 models like #CUA-S1# and #Jev# can make agent execution much more efficient.
