PRORE: A Proactive Reward System for GUI Agents via Reasoner-Actor Collaboration
PRORE addresses the limitations of existing reward systems for GUI agents, which suffer from incomplete state observability and limited domain-specific LLM capabilities. It introduces a proactive reward system leveraging a general-purpose reasoner and domain-specific evaluator agents. The reasoner schedules targeted state probing tasks, which evaluators execute by actively interacting with the environment to collect additional observations. This collaboration enables more accurate and verifiable reward assignments. Empirical results on over 3K trajectories show PRORE significantly improves reward accuracy by up to 5.3% and F1 score by 19.4%, achieving an average accuracy of 93.7%. When integrated with state-of-the-art policy agents, PRORE improves success rates by up to 22.4%, demonstrating its robustness and generalization capabilities across diverse tasks and benchmarks.

PRORE: Reasoner-Actor Collaboration for Proactive Rewards
PRORE transforms passive monitoring into proactive probing through a reasoner-actor collaboration. The reasoner (GPT-40) schedules targeted state probing tasks. Evaluator agents interact with the environment to collect additional observations, which are then summarized into verifiable claims. The reasoner uses chain-of-claims reasoning to assign accurate rewards.

Superior Performance Across Benchmarks
PRORE demonstrates superior performance compared to state-of-the-art baselines across various GUI agent benchmarks, consistently achieving higher reward accuracy and F1 scores. This robustness extends to PC and web tasks, showcasing strong generalization.
| Method | Avg Accuracy (%) | Avg F1 Score (%) | OSWorld Acc (%) | OSWorld-Chrome Acc (%) |
|---|---|---|---|---|
| PRORE | 93.7 | 83.0 | 92.0 | 93.5 |
| Step-Critic | 88.4 | 63.6 | 81.0 | 87.0 |
| WebRL | 86.9 | 62.8 | 86.0 | 87.0 |
| DistRL | 86.1 | 60.9 | 88.0 | 82.6 |
| DigiRL | 84.6 | 59.9 | 88.0 | 84.8 |
Long-term Cost-Effectiveness
While PRORE involves initial computational overhead per task due to proactive probing and chain-of-claims, its enhanced reward accuracy reduces the number of rollouts needed to achieve the same amount of useful data, leading to overall long-term savings.
Strategic ROI: PRORE in Practice
For large-scale training and evolution of GUI agents, the overall cost of collecting useful trajectories is a critical factor. PRORE, despite a slightly higher per-task evaluation cost (approx. $0.063 vs. $0.010-$0.017 for baselines), significantly reduces the number of required rollouts due to its high reward accuracy. Specifically, to collect 1,000 useful trajectories, PRORE requires 1,778.7 rollouts, compared to Step-Critic's 1,885.4 rollouts (Table 9). This efficiency translates to PRORE becoming more economical once the rollout cost exceeds $0.78 per rollout, a threshold easily met under realistic deployment conditions (e.g., GPU hosting, LLM inference costs). This makes PRORE a strategically sound investment for enterprises aiming for scalable and robust AI agent development.
Validating Design Contributions
The ablation study confirms the critical contribution of each PRORE component: proactive state probing scheduling, chain-of-claims reasoning, and iterative state probing. Each component individually improves reward accuracy and robustness.
| Probing Task Scheduling | Chain-of-Claims | Iterative Probing | Accuracy (%) |
|---|---|---|---|
| No | No | No | 88.8 |
| Yes | No | No | 89.5 |
| Yes | Yes | No | 91.4 |
| Yes | Yes | Yes (single round) | 93.1 |
| Yes | Yes | Yes (multi-round) | 94.8 |
