arXiv:2606.12837v1 Announce Type: new Abstract: Search agent benchmarks exemplified by BrowseComp have rapidly saturated over the past year, with the strongest models surpassing 90% accuracy. Since these benchmarks are predominantly human-authored, annotators lack a global perspective on entity statistics and cannot systematically maximize search space size and structural complexity. This creates a difficulty ceiling that is hard to break. To address this, we introduce LoHoSearch (Long-Horizon Search Agents), a challenging benchmark comprising 544 human-verified questions across 11 domains. Lo
The rapid saturation of existing search agent benchmarks necessitates new, more challenging evaluations to drive further AI development.
Advanced AI agents require benchmarks that push beyond current capabilities, enabling the development of more robust and autonomous systems.
The introduction of LoHoSearch provides a new, more difficult standard for evaluating long-horizon search agents, shifting the focus towards more complex problem-solving.

AI search agents will improve their ability to navigate complex, multi-step problems.
This improvement will enable agents to automate more sophisticated white-collar tasks, potentially collapsing existing workflows.
The enhanced capabilities of these agents could accelerate the development of general-purpose AI, leading to broader economic transformations.
