GAIR-NLP / SJTU · 2025
L2 · Production Agent SystemsarXiv:2603.15594 / 2605.04036#search-agent#open-source
CORE IDEA
Fact-grounded scalable controllable QA synthesis（反向构造）+ denoised trajectory synthesis，11.7k synthesized sample + 简单 SFT 击败工业级重训模型。
CONCRETE EXAMPLE
BrowseComp 29.5%(v1)→46.0%(v2)；BrowseComp-ZH 48.4% 超过通义 DeepResearch。
L-ANCHOR · 为什么在这一层重要
开源 deep research agent，证明 data quality > training pipeline complexity
