This reporting page isolates the web research slice of agentic performance. It prioritizes sourced benchmarks for browsing, evidence gathering, and multi-step web task completion rather than generic overall agent scores.
This page ranks models using only sourced web research benchmarks in the reporting family.
Bottom line: Web research agents need to browse, gather evidence, and synthesize findings. BrowseComp is the most predictive benchmark here.
GPT-5.6 Sol leads this ranking with a score of 92.2, followed by Kimi K3 (91.2) and Claude Opus 5 (90.8). The top three are separated by just a few points — any of them would perform well for this use case.
The best open-weight option is Ornith-1.5-397B (ranked #8 with a score of 86.6). While proprietary models lead, open-weight options are within striking distance for teams willing to trade a few points of performance for full model control.

Known limitations
Web research benchmarks test specific browsing patterns. Real-world web research also depends on access to search APIs, page rendering quality, and anti-bot measures that benchmarks do not capture.
