Agents stumble when work crosses devices

What changedJarvisGUI builds tasks that cross Android, Windows and Ubuntu instead of testing an agent inside one tidy application. Leading open agents struggled to carry state between devices, preserve context and finish long chains of dependent actions. The benchmark exposes a mundane but important truth: real work often changes screens, operating systems and interaction styles halfway through.

JarvisGUI overview of long workflows spanning Android, Windows and Ubuntu

The useful part

Why it matters

Cross-device failure is a better warning for automation builders than a high score on isolated clicks inside one application.

Worth doing

What to do next

Add explicit handoff state, checkpoints and recovery tests before asking an agent to span a phone and desktop workflow.

Keep in mind

Good to know

The benchmark focuses on open agents and dynamically composed tasks; results may change quickly as systems and environments improve.
