BrowseComp-Plus

Fits search agents that run over an internal document store rather than the open web. Borrow the fixed corpus with human-verified positives and mined hard negatives, and the separate retrieval metrics (nDCG, recall) next to answer accuracy.

What it asks the agent to do

  • answer a multi-hop BrowseComp question using only a fixed document corpus
  • plan and issue searches against a retriever, then reason over the hits
  • cite the documents that support the answer

Caveats

The corpus is about 100K documents chosen around the questions, so it is easier than the open web; the LLM judge is Qwen3-32B; leaderboard entries are submitted by email.
