12月10日，一份最新研究显示，美国生鲜外送平台Instacart使用的人工智能定价工具，让消费者在同一家店购买相同商品时，付出不同价格。这份由进步派团体Groundwork Collaborative、Consumer Reports 与新闻组织More Perfect Union于周二发布的研究，邀请来自四座城市的437名购物者，在Instacart App中于同一家零售商选取相同商品加入购物车，以观察是否出现定价差异。
结果显示，近75%的测试商品对不同使用者呈现不同价格。针对同一家店、同一篮商品的比较中，总价格最多可相差约7%，Groundwork表示，若此差距持续一年，等同于每年约1200美元的成本差异。Instacart回应称，只有少数合作零售商进行有限的线上定价测试，且这些测试并未使用个人、人口统计或个别行为资料；公司强调，价格也不会随供需或即时因素改变。
