SeekJudge: A New Reward Framework for Computer-Use Agents

ai-technology · 2026-07-29

There's a new research paper out that introduces SeekJudge, a groundbreaking reward system designed for reinforcement learning in AI agents. This system addresses the challenge of evaluating if a path aligns with instructions in long-term GUI tasks. Traditional rule-based methods often miss the mark on human intent and can become outdated with app updates. Current model-based judges haven't quite reached the effectiveness of rule-based ones. SeekJudge employs four unique agents—Condense, Ground, Seek, and Analyze—that work together in a Seek-Analyze loop to assess outcomes. A specially calibrated distillation process trains a combined 9B model to serve as the foundation for these agents. Remarkably, SeekJudge is the first model-based reward system to match or exceed rule-based evaluations based on downstream success rates. You can find the paper on arXiv under the ID 2607.23263.

Key facts

  • SeekJudge is a reward framework for reinforcement learning in computer-use agents.
  • It uses four role-specialized agents: Condense, Ground, Seek, and Analyze.
  • The agents reach a verdict through a Seek-Analyze loop over the trajectory.
  • A seed-calibrated distillation pipeline trains a single 9B model as shared backbone.
  • SeekJudge matches or exceeds rule-based evaluation on held-out RL test goals.
  • It is the first practical model-based reward to achieve this.
  • Rule-based evaluation struggles with aligning to human intention and becomes outdated.
  • Existing model-based judges still lag behind rule-based evaluation.
