BrowseComp (context management)

Finding difficult information through web browsing and search.

Web researchOpenAI, reported by Reflection AIVendor-reported onlyReported by Reflection AI

How it is run

Reflection AI explicitly reports BrowseComp with context management for four models. Beam’s published score is 77.4%.

What it cannot tell you

Context-management and browsing configurations affect results. These figures should not be treated as a controlled comparison with other BrowseComp setups.

Why there is no independent table

No independent suite in this dataset runs BrowseComp (context management). The numbers below are the ones model publishers report about their own models, which is a different kind of evidence: each publisher chooses its own harness and effort level, so a row is readable on its own and not against the other rows.

Ranks compare reported scores in the same published row; ties share a rank.

Reflection AI’s four capability tables, read 6 October 2026. All 21 rows and eight model columns are transcribed; NR means not reported and remains blank. The source’s Qwen 3.8 Max column uses this catalogue’s Qwen3.8 Max spelling. Beam results are publisher reports; Reflection AI cites Artificial Analysis and Datacurve for comparison-model evaluations. The announcement does not specify a common harness, effort or trial count for every row. Ranks are derived within each published row from reported values only, with ties sharing a rank; they do not establish an independent or overall model ranking. AutomationBench uses the public split; AA-Omniscience is an index on the public split only, calculated by Reflection AI. BrowseComp and DeepSearchQA use context management. AA-LCR has no stated version. These settings remain separate from other source fields.
