[Taobao Flash Sale Releases Open-Source Risk Control Model 'Baize' for Dining and Retail Scenarios] Reporters have learned that Taobao Flash Sale has officially launched a vertical open-source risk control model tailored for dining services and retail stores—'Baize' (Ostrakon-VL)—and announced that the related technical capabilities will be freely available to the entire industry. It is reported that the model is deeply trained and optimized based on Alibaba Cloud's Tongyi Qianwen Qwen3-VL-8B foundation, specifically adapted to the unique needs of dining and retail store scenarios in vertical domains. The primary technical advantage lies in its extremely high parameter efficiency. According to evaluations by ShopBench (a public benchmark serving dining and retail stores), 'Baize' significantly outperforms foundation models of the same scale in performance scores, maintaining robust perception and decision-making capabilities even in real-world store data with strong noise and high heterogeneity. Currently, 'Baize' has been integrated into over 100 production scenarios within Taobao Flash Sale, with call volumes exceeding the 10-billion level and token consumption surpassing the trillion level.
