This research introduces PrimeSeeker, a new framework for training deep search agents that prioritizes local retrieval capabilities over synthetic difficulty metrics. By decomposing complex queries into chains of coupled operations centered on "latent anchor reasoning," the method significantly reduces tool call redundancy while maintaining strong performance across benchmarks. The approach offers a more efficient path for scaling autonomous search systems by aligning training objectives with actual retrieval mechanics rather than just trajectory length.
PrimeSeeker: Capability-Oriented Supervision for Deep Search Agents
arXiv:2609.35816v1 Announce Type: new Abstract: Large language model search agents are often trained with synthetic questions whose difficulty is increased through larger evidence graphs, additional hops, and longer trajectories. These global properties, however, are only indirect proxies for the local retrieval capabilities required during search. To address this mismatch, we introduce latent anchor reasoning, which consists of resolving an unnamed retrieval anchor from descriptive specifications and transferring the recovered anchor into a subsequent information demand. This primitive retrieval unit decomposes deep search into chains of coupled operations and organizes question construction around anchor resolution and relation transfer, without prescribing a canonical search path. Based on this formulation, we propose PrimeSeeker, a capability-oriented framework that constructs web-grounded anchor structures and jointly derives a question and a reference evidence skeleton. The skeleton preserves supporting evidence from construction and guides expert generation through extractive highlights of current tool observations. These highlights are removed before supervised fine-tuning, while the skeleton is subsequently reused to audit reference-step coverage for reinforcement-learning rewards. We construct 9,221 expert trajectories, training a 30B search agent. Across five deep-search benchmarks, PrimeSeeker achieves strong performance, while reference-step optimization further improves the supervised policy. The resulting trajectories exhibit low retrieval redundancy, and fixed-budget evaluation shows strong solution coverage with substantially fewer tool calls than long-horizon systems.
