OpenResearcher pipeline enables offline synthesis of AI research trajectories

By PulseAugur Editorial · [1 sources] ·

Researchers have developed OpenResearcher, an open-source pipeline designed for synthesizing long-horizon research trajectories for training deep research agents. This pipeline operates offline, utilizing three explicit browser primitives over a 15 million document corpus, which allows for reproducible and cost-effective data collection compared to proprietary APIs. By using GPT-OSS-120B as a teacher model, they generated over 97,000 trajectories, leading to a significant improvement in accuracy on benchmarks like BrowseComp-Plus when a 30B-A3B model was fine-tuned on this data. AI

IMPACT Provides a reproducible and cost-effective method for generating training data for deep research agents, potentially accelerating development in this area.

    OpenResearcher: A Fully Open Pipeline for Long-Horizon Deep Research Trajectory Synthesis

    arXiv:2603.20278v2 Announce Type: replace-cross Abstract: Training deep research agents requires long-horizon trajectories that interleave search, evidence aggregation, and multi-step reasoning. However, existing data collection pipelines typically rely on proprietary web APIs, m…
