They tested all 18 combinations in full; the experimental volume is substantial, and the NUS team has truly proven its capabilities.

NUS team releases the GameWorld benchmark, including 34 browser games and 170 tasks, with verifiable metrics for objective evaluation. Tests two types of proxy interfaces: computer-use, which involves direct keyboard and mouse commands, and a general multimodal proxy that operates within semantic space. Empirical results on 18 model-interface combinations show that even the best performers are far below human levels, with challenges remaining in real-time latency, context memory sensitivity, and action effectiveness.
