Definition
Plain language
An open-source search agent used as a baseline in deep-research-agent comparisons.
As stated in the literature
An open-source search-agent system used as a comparison baseline against OpenSeeker and other multi-hop research agents.
Why it matters: Open-source baselines like RedSearcher make claims about new agents falsifiable, since anyone can re-run the comparison.
For example, when evaluating a new deep-research agent on multi-hop questions, researchers compare its accuracy and latency against RedSearcher running on the same queries.
