PersonaTrail (AWM) - Single-hop Preference Inference: leaderboard
PersonaTrail (2026) evaluates personalized web agents on live websites that must resolve under-specified requests from a raw browsing history, run through the Browser-Use agent framework. Task success in percent on single-hop preference inference (infer a missing preference from recurring behaviour), with history supplied through AWM workflow memory; higher is better.
Metric: Task success rate (%; single-hop preference inference: an under-specified query whose missing preference must be inferred from recurring browsing behaviour; success needs the right website, the task intent and the preference all satisfied; live websites through a Browser-Use web agent with at most 30 steps and temperature 0, given memory from AWM (per-user workflow memory induced from past action trajectories); Gemini 3.1 Pro evaluator; the three proprietary backbones run on a 25% stratified subset).
