Reporter's hands-on test of AI bill calculations during Double 11: Taobao, Doubao, Tongyi Qianwen, and DeepSeek frequently make errors in discount calculations
An IT Times reporter's hands-on test found that Taobao's built-in AI assistant, Doubao, Tongyi Qianwen, and DeepSeek frequently made errors when calculating order totals to hit spending thresholds during Double 11: Taobao's AI calculated 1,546 yuan as 1,670 yuan; Doubao ignored channel coupon restrictions, causing the actual payment to rise from an expected 520 yuan to 734 yuan; and the three models' estimates for a 2,500 yuan order had errors of up to 500 yuan. JD.com's AI shopping feature requires downloading a separate standalone app and cannot read items in the shopping cart. Taobao's AI assistant can dynamically calculate prices based on the coupons currently available in the user's account, but its order-splitting suggestions still fall about 100 yuan short of reaching the full-reduction threshold.
