BrowseComp (10-agent, prerelease)
Sections 8.11.1 and 8.11.4 report 93.6% for the 10-agent team. The card says these runs used a pre-release configuration without safeguards and are useful for relative, not absolute, comparison; BenchLM therefore keeps the row display-only and explicitly labeled.

How to read this leaderboard
BrowseComp is OpenAI’s 1,266-question browsing benchmark. Solving a question can require repeated searches and gathering clues from several pages. The short-answer format makes grading easier but narrows what the result measures.
Variant check: Match the browser tools, model configuration, search budget, and number of attempts before comparing rows. BrowseComp and BrowseComp-Plus use different evaluation environments; their percentages belong in separate tables.
Use BrowseComp as evidence about difficult web retrieval. It does not establish how well an agent writes a cited report, checks every source, or handles the distribution of questions in your product. Test those jobs separately.
Operator receipt: 61 sourced rows are currently displayable on this page; the leading published row is Atria Dawn Preview at 92.5%.
Honest limit: OpenAI notes that the relationship between short-answer BrowseComp performance and real users’ open-ended questions is unclear. Multi-attempt results and single attempts are not interchangeable. API list prices are not measured evaluation costs.
According to BenchLM.ai, Atria Dawn Preview leads the BrowseComp benchmark with a score of 92.5%, followed by GPT-5.6 Sol (92.2%) and Kimi K3.1 Pro (92.1%). The top models are clustered within 0.4 points, suggesting this benchmark is nearing saturation for frontier models.
61 models have been evaluated on BrowseComp. The benchmark falls in the Agentic category. BenchAlign v5.8 gives BrowseComp 8% of the Agentic reference weight, so it moves the Agentic leaderboard and the overall ranking. Reference weights are relative weights in the calibrated model, not fixed shares of a score.
