Desktop-Delta Bench: Do Computer-Use Models Understand Desktop GUI Transitions?

Computer-use agents (CUAs) increasingly act through desktop GUIs to complete long-horizon tasks.

Computer-use agents (CUAs) increasingly act through desktop GUIs to complete long-horizon tasks. Current benchmarks primarily measure end-task success or single-frame grounding. Neither isolates whether a model can reconstruct the causal, task-relevant transition produced by an…
