Shopping Reasoning Bench: leaderboard

Shopping Reasoning Bench (Amazon, 2026) evaluates conversational shopping assistants on 525 expert-authored single- and multi-turn missions graded against 10,863 importance-weighted binary rubrics by a Claude Sonnet 4.5 judge, with each model using its native web search. The score is the weighted rubric pass rate in percent over all missions; higher is better.

Metric: Weighted pass rate (%) over all 525 expert-authored shopping missions scored by importance-weighted binary rubrics written by retail domain experts (weighted pass rate); each model answers with its native web search tool at default inference settings and a Claude Sonnet 4.5 judge (temperature 0) grades every rubric; mission-weighted mean of the single- and multi-turn subsets; higher is better.
