WANDR: leaderboard

WANDR (Wide ANd Deep Research, Perplexity, 2026) is a benchmark of 500 agentic data-collection tasks drawn from de-identified product-usage logs, each asking a system to find many qualifying members and establish cited facts about each, with a task-specific judge that re-fetches every cited page. Soft F1 in percent, averaged over tasks, gives partial credit to incomplete members and zero-pads unmet required counts; higher is better.

Metric: Soft F1 (%; x100 of the 0-1 harmonic mean of soft precision and recall, where incomplete members earn partial credit and recall zero-pads unmet required counts; one run per system over all 500 WANDR tasks, each asking for n x m x k qualifying records with cited source pages; a task-specific judge (pinned GPT-5.4 configuration) re-fetches every cited page and verifies each record's claims (verdict_full); per-task scores averaged without weighting, errored trials counted as 0). Source: arxiv.org. Saturation forecast: Around 2029. 6 models tracked.
