The benchmark
DeepResearch-Bench runs each agent on a set of real, multi-step web-research tasks — the kind that require planning a search, reading across many sources, and writing a cited report. An LLM judge scores every report on comprehensiveness, insight, instruction-following, and readability, and — for a subset of agents — audits citation accuracy, the share of a report's citations that genuinely support their claims. The overall score is the composite across those dimensions.
