What it measures

Questions whose answers are short and easy to verify but hard to find, forcing an agent to plan, search persistently and combine evidence across many pages.

Beyond public benchmarks

Get a private eval built for your model.

Browsing agents are judged on what they can find. We write expert research tasks with verified answers in the domains your users actually search.

  • Unpublished tasks written by vetted US-based subject-matter experts
  • Rubric-based grading with expert review, not just automated scoring
  • Delivered under NDA, with training data to close the gaps it finds
