部分语言使用AI模型成本更高:词元用量最多相差5倍

一项由“AI研究语言平等联盟”开展的研究发现,大语言模型处理部分较不常用语言时,所需词元数量最多可达英语的5倍,这意味着使用者将承担更高费用并可能遭遇更慢的响应。

事件概述

一项由“AI研究语言平等联盟”(Coalition for Language Equity in AI Research)开展的研究发现,与英语相比,大语言模型处理部分较不常用语言时,所需的词元(token)数量最多可达5倍。对使用这些语言的用户而言,这意味着成本更高,部分场景下的响应速度也更慢。Computerworld就此研究发布了报道。

大语言模型通常按词元计费,并按词元处理输入与输出,因此词元用量直接影响每次请求的费用和处理时长。研究的核心结论是,同样的语义内容,在某些语言中需要消耗明显更多的词元,这种差距会转化为用户实际承担的成本差异。

报道目前所依据的信息主要围绕研究结论本身,尚未涉及具体模型供应商的定价调整或应对计划。

为何重要

对于正在把AI嵌入客户服务、内容生产和内部流程的企业与政府机构而言,这项研究把一个常被忽视的问题摆到了台面上:使用体验的公平性,不仅取决于模型能否理解某种语言,还取决于使用该语言的成本与速度。当同一项服务对不同语言群体的价格和响应时间存在差异,用户感受到的便是体验上的落差,而这种落差往往在产品设计阶段就已经埋下。

这一发现也提示,AI项目的评估框架需要从单一的准确率或总体成本,扩展到按语言、按用户群体拆分的单位成本与延迟指标。对数字化转型负责人而言,这意味着在选型、预算测算和服务上线前,就应把多语言场景纳入测试范围。

Renascence观点

多数读者会把这条新闻理解为一个技术定价问题,但它更本质的是服务设计问题。当一项数字服务的成本结构与用户的语言身份挂钩,用户感知到的便不再是“产品好不好用”,而是“这个产品是否为我这样的人而设计”。

大多数团队会把语言成本当作后台的账单问题,然而用户会在第一次收到更慢的回复或更高的账单时,就对品牌形成判断。真正以客户为中心的运营方,应当在上线前按语言绘制成本与延迟地图,而不是等到投诉出现后再补救。更重要的是,把多语言成本纳入体验指标,让产品、财务与服务团队共同对这一数字负责。这一做法的前提,是承认公平的体验必须从数据和设计的源头开始建立。
