The paper reports higher conversion and high-intent merchant growth without updating model parameters, making the case notable for teams designing agents that learn from outcomes across repeated interactions.","published_at":"2026-11-06","updated_at":"2026-11-06","record_date":"2026-11-06","date_kind":"published_at","topics":["engineering-management"],"entities":["Alibaba","SPAR","1688","Hangming Zhang","Yao Zhao","Haotian Kuang","C.
