Taobao Flash Sale releases open-source large model "Bai Ze" for risk control management in dining and retail scenarios

Reporters learned that Taobao Flash Purchase officially launched an open-source risk-control governance vertical-domain large model specially built for food service and retail stores—“Bai Ze” (Ostrakon-VL)—and announced that the related technical capabilities will be made available to the entire industry free of charge. It is understood that the model is based on Alibaba Cloud’s Tongyi Qianwen Qwen3-VL-8B foundation model and has undergone deep training and tuning; it has been vertically adapted to meet the special needs of scenarios involving food service and retail stores. In terms of technical performance, its main advantage is extremely high parameter efficiency. According to evaluations on ShopBench (a public benchmark serving food service and retail stores), “Bai Ze” achieves a significantly higher performance score than same-scale foundation models, and even with strong noise and highly heterogeneous real store data, it can still maintain robust perception and decision-making capabilities. At present, “Bai Ze” has already been integrated into more than 100 production scenarios on Taobao Flash Purchase, with call volume exceeding the 1 billion level, and its Token consumption has surpassed the trillion level.
