ZooWork-ShopRanker: LLM-judge-aligned open e-commerce rerankers from 0.6B to 8B
Siqiao Xue · hf · 2026-09-28
ZooWork-ShopRanker releases open e-commerce rerankers (0.6B/4B/8B) trained on pairwise labels from a panel of reasoning LLMs acting as a preference oracle, plus ShopRank-Bench (10k private-traffic preference pairs). The 8B and 4B beat the strongest open reranker baseline, gains hold across formats and MTEB.
